Tracking Some Howorth/Howarth DNA from Bacup, Lancashire

My Hartley ancestors came from Trawden, Lancashire. They were hand loom weavers. Due to the industrialization of weaving, hand loom weaving became obsolete. At that point, the family moved to Bacup, Lancashire where there were weaving mills. There, my ancestor Greenwood Hartley married a local Bacup girl named Ann Emmet. Ann Emmet was the daughter of Esther Howorth b. 1800 and Isaac Emmet. My web page on the Howorth family mentions that she was born either at Nun Hills, Bacup which I identified on a map or Nothill, Bacup. So there is some confusion with names within Bacup.

Anne from Australia: DNA Match and Howarth Descendant

Anne is about the perfect DNA match. She has a tree at Ancestry. She has uploaded her results to Gedmatch.com and she is from Australia. Being from Australia is important. That is because, as I live in Massachusetts, it is not likely that the match is on one of my colonial Massachusetts lines. She has her ancestor as Howarth rather than my Howorth, but I don’t think that is a big deal as these names are so close.

Anne’s Genealogy

Anne’s Howarth Line is on her paternal grandmother’s side:

Anne’s Howarth line goes out as far as James Howarth, born 1768. That would be Anne’s 4th great grandfather. This matches up well with my tree:

This is my grandfather’s tree and I also have a James Howorth born 1768. If Anne and I have our trees right, that would make us 5th cousins.

There were a bunch of Howorths born around the time that Esther and Abram or Abraham were baptized. Here is what Ebenezer Particular Baptist Church looked like around the time they were baptized:

For DNA comparisons, I like to draw top-down trees:

Anne is thinking like me and has had a DNA test for her 1st cousin once removed. Those results should be in in about a month. I have other 2nd cousins that have tested for DNA, but have just put Beth in this tree for now as I believe she has a match to Anne. Let’s assume that the tree is right. That would mean that Esther and Abraham were siblings. Ann Emmet and Elizabeth Howarth were first cousins and should have known each other. James Hartley b. 1862 should not have known Fred Taylor as James moved to Massachusetts with his family in 1869 before Fred was born.

Anne’s DNA

Anne matches me and my three sisters on Chromosome 4:

The first three matches are of 15.8 cM. In my view, any match of 15 cM or more is almost certain to be a genuine match. My brother Jonathan doesn’t match there as he is matching on his paternal grandmother’s side (Frazer) at that location.

Mapping Anne’s DNA Match to My Chromosome Map

That means that I can map that Chromosome 4 segment to either Abraham Howorth or his wife Mary. As I don’t know from which ancestor it came from, I can say one of those parents gave that DNA to their daughter, Esther Howorth b. 1800 for sure. So I will map that Chromosome 4 segment to her:

This is not a big segment that is added in lighter blue, but it about doubles what I had already on Chromosome 4. Also it goes back in time three generations from what I had belonging to either James Hartley or Annie Snell shown in darker blue.

Anne’s Chromosome 8 – We Have Triangulation

Here is how Anne matches some of my relatives on Chromosome 8:

These matches are with Joyce (1), Beth (2) and Patricia (3). I already mentioned Joyce and Beth above. Patricia is Beth’s first cousin and my 2nd cousin. For this to be a Triangulation, Joyce has to match Beth and Patricia and Patricia has to match Beth on this same segment. That is quite likely.  Here is how Joyce matches Beth and Patricia on Chromosome 8:

This is definitely a Triangulation Group. That Group can be visualized this way:

I should note that there a few other of my second cousins that did not match Anne. The point is that it takes a few people testing to get these triangulating results when the common ancestors are born in the 1700’s.

Summary and Conclusions

  • Anne’s combination of where she lived, her DNA matches at Gedmatch.com and Ancestry and her good family tree all helped in this analysis
  • My match with Anne gave me a new mapping area on the paternal side of my Chromosome 4.
  • Anne’s matches would also supply some good mapping for Joyce, Beth, Patricia and my sisters as well as for Anne herself.
  • My conclusion is that the DNA triangulation shown above gives pretty convincing evidence that Esther Howorth b. 1800 and Abraham Howorth b. 1814 were siblings.
  • Now all we have to do is to figure out who Mary is that was married to James Howarth.

 

 

 

Cousin Mike Joins the Fray

I was presently surprised when looking over my AncestryDNA matches recently. I saw my second cousin Mike. Now due to the fact that I have many second cousins descending from James Hartley and Annie Snell, I don’t happen to know them all personally. Fortunately, I do know Mike and if I met him somewhere would surely say hi.

Mike at AncestryDNA

At AncestryDNA there is a button to push called Shared Matches. When I look for Shared Matches between me and Mike, I get a lot of people. I first get my 4 tested siblings. Then I get 11 second cousins. These are actually 2nd cousins by DNA. In other words, Ancestry looks at the amount of DNA shared and guesses that these should be in the 2nd cousin range. So Ancestry has the first four of my list of shared second cousins in the 1st to 2nd cousin range. The rest on the list are in the 2nd to 3rd cousin range. However, these are all actual second cousins that Mike and I share. These would be descendants of the 13 children that my great grandparents James Hartley and Annie Snell had. Actually, first on his list of 2nd cousins is Joyce. She is a first cousin once removed. I had her tested at the last family reunion. I wrote a Blog about her results here, and about Mike’s sister Holly here. Down in the Third Cousin Shared Matches there may be 2nd cousins once removed. There is also one non-Hartley Snell relative listed there.

Mike at Gedmatch

I asked Mike to upload his DNA results to Gedmatch. That is where you can find out more about your DNA. For example, here is how Mike matches his sister Holly on Chromosome 15:

I bring up this example, because full siblings match each other in a different way than any other relationship.

  • We all get a chromosome from our mom and one from our dad. They in turn got one from their mom and one from their dad. That means there are four ways that we can get DNA from our parents. Those four ways are from our four grandparents
  • The blue bar on the bottom shows where Mike and Holly match by DNA.
  • The yellow bar above the blue means that Mike and Holly share the DNA from one parent only. And they get their DNA from only one parent of that parent. However, we don’t know which one right now.
  • The green bar above the blue bar means that Mike and Holly share DNA from both their mother and father. Not only that, they share the DNA from one of the mother’s parents and one of the father’s parents. However, we don’t know which one yet.
  • The red area is where Holly and Mike share no DNA from either parent. That is the opposite of the green area. That means Mike may get his DNA from a maternal grandfather and Holly from a paternal grandmother in that area. I’ll give some examples below.

Here are Mike and Holly’s grandparents:

Here is how Mike and Holly match each other on Chromosome 7:

Below the first green bar (which is called a Fully Identical Region or FIR), I have split this out for Mike and Holly. This is split to identify Mike and Holly’s maternal and paternal sides (but we don’t know which yet). Mike and Holly have two of the same colors. That means that they got the DNA from the same two grandparents. One of those grandparents is paternal and one is maternal. We don’t know which is which yet, but we can easily figure out the paternal grandmother. We can do that because all of Mike and Holly’s second cousin DNA matches on the Hartley side that I mentioned above.

The first match is Mike’s 1st cousin once removed Joyce. Then there are my 4 siblings. #6 and 7 are two other Hartley-descended 2nd cousins. That means that all this DNA maps to Mike’s grandmother Grace May Hartley. Put together, these matches go from 15.6M to 95.6M for Mike.

Here I assigned blue as Mike and Holly’s paternal grandmother. In the green area, Holly had to have the same DNA from the same Hartley grandmother. In the red area, Holly had to have the DNA from her Gifford grandfather because neither grandparent matches in a red area. Now let’s look at Holly’s 2nd cousin matches.

Above, Holly matches Joyce from 6-42M.

Because Holly gets her DNA from her Hartley grandmother before about the 16M mark, that must mean Mike gets his paternal DNA in that area on his Gifford side. Otherwise, he would have matched at least one of his Hartley cousins there.  Then I moved some of the orange DNA to the left. This would be maternal DNA which is from either Jenney or Murray. This also meets the requirement of the first yellow area. That area is called an HIR or Half Identical Region. It is where Mike and Holly share the DNA from one grandparent but not the other. In order to know which grandparent that DNA is from, we would need to have a match to a Murray or Jenney. In order to do this right we would also need another color for the 2nd maternal grandparent.

This is also a lot easier when there are three siblings to compare because then we could find out where the crossovers are. An example of a crossover is on Mike’s DNA where the DNA he got on the paternal side goes from Gifford to Hartley.

Me and Mike and Our DNA

When I look at my DNA matches at Gedmatch, my match with Mike is the highest level shared between any of my second cousins – at least the cousins that have uploaded to Gedmatch. Mike’s sister Holly had the record before that. Here is what the specifics look like between Mike and myself:

At the bottom of the list is a number of 2.7 generations. That is how far back it looks like our common ancestors are based on the DNA match. They are actually 3.0 generations away. That means that we share more than the average DNA for 2nd cousins. Some of my second cousins will share more than average amounts and some will share less than average amounts of DNA. If I look at Mike’s match list, he shares more DNA with two of my sisters and another 2nd cousin than he does with me.

Mapping My DNA By Cousins

I showed one way to map DNA from your grandparents comparing siblings’ DNA. Another way is to directly map your cousins’ matches to a chart. Kitty Munson has developed some software to do this. Right now my map looks like this:

The darker blue maps to James Hartley and Annie Snell. That would be via my 1st cousins once removed and my 2nd cousins with the same ancestors. Mike’s DNA fills in a few blanks in my map:

I guess the changes are subtle. The Hartley side should only ever fill up about one half of my paternal chromosomes. The other half for me would be for Frazer and Frazer ancestors.

Mike’s X Chromosome Matches: No Hartleys There

Mike’s biggest X Chromosome match is with his sister Holly:

Mike, like me, won’t match any Hartley relatives on the X Chromosome. That is because a father never passes an X Chromosome down to a son – only a Y Chromosome. The big match between Mike and Holly is from their mom. She got her X Chromosome from some combination of Jenney and Murray.

Mike’s Lancashire DNA Match

These matches above represent Lee’s DNA matches on Chromosome 13 with 5 siblings in my family, our two 1st cousins once removed and Mike in the green.

I have mentioned in a previous Blog about Joyce, that Hartley descendants have a match with Lee at AncestryDNA and Gedmatch. Lee shows all his ancestors as being from England.

In this match, Lee’s ancestors are in orange and mine are in blue. When I zoom in to Trawden, where the Hartleys were from, I see Lee has ancestors in this area:

At the time our ancestors were in Trawden, they had to go to Colne for baptisms, weddings and funerals as there was no Church of England Church in Trawden. Colne is represented by the orange to the NW of Trawden.

The Snells came to this country in the 1600’s and the Hartleys in the 1800’s. That means that Lee’s matches would be on the Hartley side vs. the Snell side. Lee has two interesting people in his ancestry. One is Margaret Hartley b. 1836 and another is Mary Baldwin b. 1836.

  • Although these two women were both born in 1836, they are in different generations from Lee
  • Margaret Hartley is on Lee’s paternal side and Mary Baldwin is on Lee’s maternal side. If Lee were to ever test his mom, we would know on which side the Hartleys match.
  • Lee doesn’t show any parents for Margaret Hartley or Mary Baldwin

I have our Trawden born ancestor Greenwood Hartley with a Baldwin grandmother:

This is really on the edge of my knowledge. I chose Betty Baldwin and James Hartley as the most likely parents for Robert Hartley out of many potential candidates.

Lee had a dead end for his Margaret Hartley ancestor. Here are some potential parents I found for Margaret:

This was the same issue I had for finding parents for Robert. Was Margaret the daughter of John and Susan Hartley, John and Hannah Hartley or John and Margaret Hartley? Or perhaps even someone else? At least one of the Margarets died young.

Greenwood is staring at me from the past and saying, “You can’t figure out who my are grandparents are? They are _______ and _______”

a look at Mary Baldwin b. 1836

Due to a problem finding Margaret Hartley’s parents, I’ll take a look at a less common surname in Mary Baldwin. Based on this scrawly writing, she was baptized a Wesleyan in Colne:

This baptism was outside the Church of England.  A Wesleyan, perhaps what we would consider Methodist was considered a non-conformist church. Here is some information on Mary’s dad Eli:

And here is a brother of Eli:

I still need to get back a ways to get to our potential ancestor, Betty Baldwin who was born perhaps around 1780. Any potential shared ancestor would likely be Betty’s parents or before. We’ll say that Jane Baldwin was actually Jenney Spencer:

Again, we get a multiple choice for the father of this James Baldwin. Here is a batch of them from around 1790:

Here I will choose the James from Barrowford for a few reasons. One is that his dad was Elias and two, he was from Barrowford. Here is the 1851 Census showing that this James Baldwin was born in Barrowford.

This also shows James son David b. in 1812. That gets us back to the old-timers: Elias and Peggy Baldwin. Unfortunately, it looks like Elias didn’t do too well:

He died of decline at age 35. Betty could have been his daughter, but it would have made for some tight time frames. She would have had to have been born perhaps late 1783. Then she would have been only about 17 at the time of her marriage. So the genealogy is the difficult part of the genetic genealogy.

Summary

Well I looked at some aspects of Mike’s DNA:

  • How Mike and Holly have Fully Identical Regions (FIRs) in their matches with each other. Normally, these FIRs only occur between full siblings.
  • I looked at how to use the matches between Mike, Holly and their cousins to map out which grandparent they got their DNA from on certain parts of their chromosomes.
  • I looked at another way of mapping DNA developed by Kitty Munson.
  • I looked at a DNA match Mike shares with some other Hartley cousins. This DNA match is from an English man with Lancashire ancestors and probably represents deep Hartley ancestors that haven’t been identified yet.

Joyce’s Hartley DNA

At a recent Hartley reunion, I asked Joyce to take an AncestryDNA test and she gladly obliged. Joyce is my father’s cousin. I had already asked Joyce’s brother Jim to take a test at FTDNA and I have been working with his results. My father has a lot of cousins as his grandparents had 13 children that survived past infancy.

Here is a picture of Joyce and her granddaughter that my sister took at this year’s Hartley Reunion:

I remember Joyce’s mom as the one who always had cookies to give out at the family reunion. Joyce knows a lot of Hartleys as she used to be in charge of sending out letters to the relatives.

Joyce’s Genealogy – English, English and English

Here are some of Joyce’s ancestors:

The Hartley part that I am more interested in is on the bottom. Joyce has a lot of English names in her ancestry. Also a lot of Colonial Massachusetts ancestors. The ancestors that were not from Colonial Massachusetts were the Hartleys. They came to the US after the American Civil War. I’m hoping that DNA testing will confirm the last two Hartleys on the chart. They are James Hartley and Betty Baldwin. Those two were my best guess for the parents of Robert Hartley. My problem was that there were a lot of Robert Hartleys born around the same time in the area to different parents.

Ancestry has something called Genetic Communities which shows where your ancestors were in the last 200 years or so. Not surprisingly, for Joyce, her one Genetic Community is Colonial New England:

Joyce’s Matches at Ancestry

Joyce currently shows over 600 4th cousins or closer at Ancestry. That doesn’t mean that all these matches are 4th cousins. It just means that by the level of DNA match, it appears that the match could be at the level of 4th cousins. When I look at the matches, the range that Ancestry gives is actually 4th to 6th cousins. Perhaps because of all the colonial matches, some of the matches appear closer than they actually are. These matches are both on the Hartley and Gurney sides.

Shared Ancestor Hints

Ancestry also has Shared Ancestor Hints (SAHs). An SAH is when there is a DNA match to a person and also a match in the family tree. These hints are very accurate at close range, but may need checking at the more distant connections. Here is Joyce’s very accurate SAH with my sister Lori:

I’ve erased some of the information for privacy, but this shows that Lori and Joyce are 1st cousins, once removed. Joyce will show similar match results for all of my very many 2nd cousins.

Here is one of Joyce’s more distant Colonial Massachusetts cousins:

Here Ancestry has found a DNA match with this person and a family tree match with the common ancestors of Francis Crapo and Patience Spooner. This would be a good family tree match if both family trees were filled out well and there were no other matches. However, the tree on the right also shown below is missing some lines:

The match should be the bottom side of this tree. However, there is some missing information on the bottom. There are no parents for Weston, Pittsley, Reynolds, etc. However, lets assume that the DNA is actually on the Spooner side which then goes up to Crapo and Spooner. I suppose that means that Patience Crapo could have married a Spooner relative.

Joyce’s Spooner Match at Gedmatch

Once Joyce’s results came in, I uploaded them to Gedmatch.com. I like this site because you can tell a lot more about your matches. Fortunately, the Spooner/Crapo match above also uploaded to Gedmatch.

At gedmatch, I can see that the match is on Chromosome 3. Ancestry doesn’t give specific match location for their DNA matches. However, the bottom line is that wherever I or my siblings or my cousins match Joyce at this particular spot, it means that it likely represents colonial Massachusetts DNA that came through the Snell side.

People That Match Joyce and Jocye’s Crapo/Spooner Match

It is possible to run a facility at Gedmatch that shows people that match two other people that match each other by DNA. When I put Joyce and her Crapo/Spooner match, I get these people:

Above the reference person is Joyce. #3 is her Crapo/Spooner match. #1 is my 2nd cousin Patricia. She is also a 1st cousin, once removed to Joyce, so matches her in quite a few places by DNA. The other people are those who I don’t know, but they probably descend from Crapo and/or Spooner.

A Lancashire DNA Match?

As I mentioned above, Joyce has three quarters colonial Massachusetts ancestry and one quarter more recent Lancashire, England ancestry which happens to be Hartley. I found a match recently on Gedmatch which is interesting. The match is with Lee and is a fairly good size. Here is how Lee matches on Chromosome 13 with my three sisters, me, Joyce and her brother Jim:

Note that Lee matches all of us for the same amount. This means that Lee has a segment passed down from one of his grandparents that starts and ends on the yellow that matches all of us. We would have longer portions of that DNA on either side of Lee’s segment.

All of Lee’s ancestors are from England and most  from Lancashire, which would make me believe that the match is on the Hartley side. The other colonial ancestors that Joyce have go back to England so long ago, that she shouldn’t be matching on those ancestors. Here are Lee’s ancestors:

It is also interesting that Lee has a Hartley ancestor (but no information on her parents). Margaret Hartley named her son, Robert Hartley Taylor. The mother of John Clark is a Baldwin. I had mentioned above, that it is possible that there is a Baldwin in the Hartley ancestry. So that would be interesting to follow up also. Both these people were from the Colne area where the Hartleys were baptized, had funerals and married.

Another Lancashire Match in Mary Pilling

Joyce has a DNA match with two Mary Pilling descendants at Ancestry. One of those, a Wilkinson, has uploaded his results to Gedmatch. Mary Pilling is the mother of three families: Pilling, Hartley and Wilkinson. Here is how the match looks like at Ancestry:

Joyce is actually a half 3rd cousin once removed to her match. That is because after Robert Hartley died, Mary Pilling married a Wilkinson. So that makes for an obscure relationship and not much of a chance for a DNA match, but there is one. Here is how the match looks like at gedmatch:

The above represents Wilkinson’s match with Joyce and her brother Jim at the end of Chromosome 21.

Summary

Joyce’s results at Ancestry push back the matches one more generation at AncestryDNA compared to my generation. As a result, there are many more Hartley and non-Hartley DNA matches to investigate. If I can get the results of one more of Joyce’s siblings I will be able to tell where Joyce and her sibling got their DNA from each of their 4 grandparents. That would reach back to James Hartley and Annie Louisa Snell. Knowing this would make it easier to tell if their DNA matches represent Lancashire, England or Colonial Massachusetts. This may also help push back the Hartley ancestry which is currently stuck in the early 1800’s.

Chasing Down Some Massachusetts Colonial DNA

Recently I was contacted by someone I knew in high school who said, “Who knew we were related?” Skot had tested his DNA at Ancestry and had found me as a Shared Ancestor Hint. Ancestry compares your trees and if there is a match in ancestors and a match in DNA you are put on a list.

Shared Hathaway Ancestors

Skot’s and my genealogy research both lead to Simon Hathaway and Hannah Clifton.

I have the above chart to my grandfather and Skot’s grandmother. The chart says that Skot and I are seventh cousins. Simon and Hannah were born in the early 1700’s and married in Rochester, Massachusetts. This is interesting as Skot and I both grew up in Rochester.

Does Skot and My Shared  DNA Point to Hathaway and Clifton?

AncestryDNA doesn’t show that the DNA you share is the same DNA of your shared ancestor. It sort of implies that but doesn’t prove that. To prove that, we need to use triangulation and have chromosome browser. I asked Skot to upload his DNA results to Gedmatch where we could compare the DNA results. Here is what my match with Skot looks like at Gedmatch.com:

This shows that we match on Chromosome 10. I have a paternal phased kit at Gedmatch, and Skot also matched me there. That match shows that we match on my father’s side who had the Hathaway ancestors, so that is good.

Further, I have mapped my Chromosome 10 and it shows we match in an area where I got my DNA from my Hartley grandparent and not my Frazer grandparent whose parents were from Ireland. That is also a good sign:

This map shows me as J on the fourth bar. The Hartley is in orange and for me it goes from position 32M to 114M. According to Gedmatch, I match Skot from 68M to 77M, so that is well within my orange Hartley grandfather DNA area.

Triangulation of DNA

Triangulation of DNA is when A matches B, B matches C and A matches C. This is fairly easy to do. Once this triangulation occurs, it indicates a common ancestor. It is more difficult to find the common ancestor of that triangulation for various reasons. The next thing I look at is my sister Lori’s spreadsheet of matches. These matches have tested at various places and uploaded their results to Gedmatch.com. I’m looking at Lori’s matches because she matches Skot also, and because her test is more recent, so I have more matches for her.

Lori’s biggest match is 54, but that is with me. Lori matches Skot from about 68 to 77M, so these all start before that point. A few end before then. Lori has other matches in this region. Lori’s matches tested at AncestryDNA, 23andme and FTDNA. I tend to prefer AncestryDNA matches as the family trees are easier for me to read.

Lori’s first match of 22 cM is with Cheryl. Skot and Cheryl match at about the same spot and about the same cM as Lori and Skot match. That means the three triangulate.

Now the Hard Part – Finding the Common Ancestor

Cheryl has over 25,000 people in her tree. Does she have Hathaways or Cliftons? At Ancestry, Cheryl and Lori are not Shared Ancestor Hints to each other. According to AncestryDNA, the common surnames between Lori and Cheryl are:

However, Baker and Schmidt appear to me on my mom’s side, so I won’t look at those. Phillips and Warren didn’t show anything obviously helpful. When I click on Cheryl’s White, I get this:

This is interesting as I have ancestors in Dighton on my Snell Line and also White and Hathaway ancestors. With a little trial and error, I see that Elizabeth Hathaway’s mother is Elizabeth Talbot. That is one of my ancestral names also. Elizabeth’s parents according to Cheryls were Jared Talbot and Sarah Andrews. I have a match in that couple. Here is my tree:

This is what I meant when I said that finding common ancestors among triangulated matches was not easy. I’m not happy that Lori and Cheryl’s common ancestor is from the 1600’s, but at least we found a match. Perhaps we will come back to Cheryl. Right now, a tie-breaker would help. Hathaway/Clifton or Talbot/Andrews?

Skot’s Genealogy

Here is the spot of Skot’s genealogy where Ancestry has us matching:

Note that Ancestry simplified the situation a bit. We are matching on Simon Hathaway and Hannah Clifton. However, we also match on Arthur Hathaway. It is even more confusing than that because Arthur Hathaway was also the father of Simon Hathaway by his first wife Maria Luce. Wow. Then Skot has more than one Clifton in there.

Shamus Match

One of my good matches at Chromsome 10 in this area of interest is Shamus. He matches me closely at 43.8 cM by FTDNA and 39.4 by Gedmatch.com. According to FTDNA, we share the following surnames:

Barstow Cook Swift Samson Talbot Taylor Townsend White Wing Ward

I looked through these names, but saw no obvious connection before the 1700’s.

Sarah Match

Sarah matches Lori at 18 cM. She is at FTDNA. Her surnames that match are:

Clark Hatch Jewett Johnson Lutzelburger Lutzelberger Lombard Richmond Spooner Smith White Wing

At least between Shamus and Sarah are the common White and Wing names. By the way, Sarah has a different last name at Gedmatch and FTDNA, but I assume that she is the same person. Actually there is a way to prove it, because FTDNA has a chromosome browser. Here is how Sarah matches me using FTDNA’s chromosome browser:

Again, the DNA part is easy. It is the genealogy that is a bear.

Here is Sarah’s White and Wing connection:

Here is how I connect:

Again it is not a very satisfying connection. We connect only on Daniel Wing at the top. Our ancestors appear to be from two different mothers and Daniel who was born in 1617. I wasn’t able to place Sarah’s Hannah White.

I didn’t find out much about Joanne or Joanna Hatch. I did read an account of a family tradition that said that Joanna and Bachelor Wing were cousins.

At this point, I’m ready to call it quits.

Summary of Genealogy Linked to DNA

So far I match:

  • Skot on Hathaway/Clifton – early 1700’s Rochester, MA
  • Cheryl – Talbot/Andrews 1640’s Dighton, MA
  • Shamus and Sarah – Wing 1617 Sandwich, MA

I’m sure there are other connections.

Continuing to Work Down My Sister Lori’s Match List

There are some 23andme matches, but I have no idea how to find their ancestry without contacting them. Next I see Michelle. I am able to find her using a Chrome add-on to AncestryDNA which I think is called DNA Helper. She matches at 22 cM at Gedmatch. Oddly, she matches at 27.6 cM at AncestryDNA where the matches are usually less than at Gedmatch. Unfortunately, her tree is private. I have been in touch with her by email and she says she is related to the Hatch family somehow. The next match is Sean at FTDNA, but he has no family tree.

Summary and Conclusion

  • The DNA shows that there is a common ancestor between the paternal matches that I have on a particular segment of Chromosome 10
  • Finding the one common ancestor of a triangulated group is difficult
  • It is likely that there are holes in the ancestry trees of these Chromosome 10 matches. If all those holes were filled in, then the common ancestor may become apparent.
  • While I was doing this exercise I filled in some missing ancestors on my Jewett line. One ancestor was a Reverend up in Rowley which I found interesting. So this exercise wasn’t a total waste of time.
  • Skot and I still likely match on Hathaway and Clifton. However, the DNA tests we both took don’t necessarily point to those two ancestors.
  • At this point, the only triangulated ancestors I found in this Chromosome 10 group was Daniel Wing from Sandwich b., 1617.
  • In summary, the DNA is saying that there is some kind of colonial Massachusetts ancestry passed down. However, whether that ancestry is from Dighton, Rochester or Sandwich, MA or even somewhere else is not clear.

 

 

 

 

Cousin Holly’s Hartley DNA Results

I have many 2nd cousins. Over 100 I’m sure. My Hartley great grandparents had 13 children. All their descendants in my generation are 2nd cousins.Holly is one of those 2nd cousins. My first recollection of Holly is that she was creating a bit of commotion at our Town’s ball field. I was probably about 5 years old at the time. I had an impression that she may have been a relative but I wasn’t sure. Holly was challenging the local boys in a foot race and beating them. I was thinking that she was one cool girl.

So far on my Hartley side, those in gold below have tested and uploaded and uploaded to Gedmatch.com:

Note that Patricia and Beth are also first cousins to each other.

Here’s Holly’s grandmother Grace Hartley. I borrowed the photo from Holly’s Ancestry Tree:

Does she look like Holly? I think so. Except I don’t picture Holly as looking as serious.

All the Hartley cousins in the chart above have James Hartley and Annis Louisa Snell in common. But we won’t know which – easily. Another point is that everyone has eight great grandparents. So all the second cousins get 2/8 or 1/4 of their DNA from these two great grandparents. That is, on average. Here are the numbers of how Holly matches the tested Hartleys:

The Gen is how far it seems that the common ancestors are away based on the DNA match. James, my dad’s 1st cousin seems 2.5 away. That is just right for a 1st cousin once removed. Holly should match her 2nd cousins on average at a level of three. That is because our great grandparents are 3 generations away from us. Because of the random way we get our DNA, however, Holly is more closely matching Joel, Beth and Patricia and is further away matching on my four siblings.

The X Chromosome Rule

There is a rule that the X Chromosome does not pass down from father to son.

That means that no X Chromosome from Greenwood Hartley got passed down to any of us. That also means that no Hartley X Chromosome got passed down to anyone in my family. That is why Holly matches James, Beth and Patricia on the X Chromosome and only incidentally matches Lori and Heidi from my family.

Here is how Holly matches James, Beth, Patricia and incidentally my 2 sisters.

Holly and Jim have a longer match as they are more closely related (1st cousin, once removed). As a rule, the more closely you are related, the longer the segments.

Shared Autosomal DNA

Holly and I share this much DNA:

By comparison, here is my overall Chromosome map before I add in my DNA matches with Holly:

On my map, the James Hartley/Annie Snell part is shown in darker blue. It looks like Holly’s DNA could add quite a bit to my map. Ideally, if I could test enough relatives, the dark blue whould fill up 1/2 of my paternal chromosome. The other half should be from my paternal grandmother who was a Frazer.

Here is Holly’s DNA added in. I also added a maternal first cousin who contributed to my first substantial X Chromosome match:

Remember I get no X Chromosome from my dad (top part of each line). So that has to be blank on the X Chromosome.

Next I’ll add in 1st cousin once removed Jim to Holly’s map:

Jim’s contribution to our great grandparents is in blue. Notice that now the X Chromosome is kicking in.

Adding beth’s DNA to Joel and Jim

Here is the addition of Beth’s DNA:

Note that Holly has a lot of matches on Chromosomes 5 and 9. That must mean that Holly got most or all of her paternal DNA on that Chromosome from her Hartley grandmother, Grace May.

Kicking it up a notch

Next I’d like to add my siblings’ results to ‘the other matches on Holly’s Chromosome map. My siblings’ results plus mine should be similar in size to Holly’s matches with Jim, my dad’s first cousin. It takes 5 siblings to get about the same DNA as you would have for one parent. While I’m at it, I’ll add Patricia.

This is all Holly’s DNA that she got from James Hartley and Annie Snell, her great grandparents based on the matches that we’ve looked at so far. I probably should have lumped Beth and Patricia together as they have the same Hartley grandmother [Mary], but I didn’t.

Separating the Hartley and Snell DNA

One thing I would like to do would be to separate the Snell DNA from the Hartley DNA. If I could do this I could find matches that were just Snell or just Hartley. The DNA matching is about narrowing down the possibilities. The best way to do this would be to have a match that is known to be a Snell but not Hartley or a Hartley but not Snell. Unfortunately, I don’t know of any such people. The next best thing to do is to guess. One way to guess is called phasing by location. So, say I have a match with a lot of ancestors from colonial New England, but not Lancashire. And I would need to know that I match this person on my Hartley side (not my mother’s side). I would say that this would likely indicate DNA from the Snell Line. That is because the Snell ancestors go back to Colonial New England and the Hartleys came later from Lancashire, England.

My Chromosome 16

Here is a section of the first part of my Chromosome 16 matches (without the matches’ names) in spreadsheet form:

Each line represents a different match with someone. About half way down this list I have a match with Ned at 39.93 cM. I don’t know who our common ancestor is, but Ned has a lot of colonial New England ancestors, including the Warren Pilgrim family. I also am descended from the Pilgrim Warrens, but it is generally thought that a DNA match that large would be likely to last that long.

Triangulating with ned

Triangulation shows what common ancestors unknown DNA matches may have. Triangulation is when you match someone’s DNA, they match another person’s and you and the other person all match. Successful triangulation shows that all the DNA came from the same ancestor.

Here is my match with Ned:

Here is Holly’s match with Ned:

To close the loop, I have to match Holly in the same area of Chromosome 16:

No problem. This shows that Holly, Ned and I share an ancestor. By Ned’s Ancestry Tree, we think this is a New England Colonial ancestor, but we aren’t sure which New England Colonial ancestor it is. However, as Annie Snell has New England Colonial ancestors and James Hartley doesn’t I am pretty sure I can assign this segment to Annie instead of James.

This means I can update my Chromosome map with my first New England Colonial piece of DNA represented by Annie Louisa Snell on Chromosome 16. This is shown in light blue:

The other interesting thing about this piece of DNA, is that it not only is from Annie Louisa Snell, it is also from some New England Colonial person – the one I haven’t figured out yet that we have in common with Ned.

Other New England Colonial Connections Between Holly and Me

AncestryDNA recently came out with a new feature called Genetic Community. That feature lumps you into a group with a bunch of other people based on your DNA testing. One of those groups is called Settlers of Colonial New England. Here are my Genetic Communities (or GCs).

Notice I get a Likely rating for those Colonial Settlers. Holly, on the other hand, has one Genetic Community:

She gets a Very Likely. That means she is super Colonial New England. Holly has a Connection Link under her Settlers of Colonial New England. Under that link is another link that leads to “…a list of all 238 of your DNA matches who also belong to this Genetic Community.” Under my similar link I have 110 DNA matches. However, Ned that I mentioned above matches me under Settlers of Colonial New England. He doesn’t match Holly in her list for some reason – even though I showed that we triangulate. In addition, Holly and I match each other on our lists of DNA matches under Settlers of Colonial New England.

Summary

There’s plenty more I could have written about, but I’m a gonna wrap it up:

  • Holly is more Colonial than I. I expect her other non-Snell ancestors contributed more in this area
  • I looked at a way to separate out ancestral DNA when other reference matches are missing
  • We are getting a good group of Hartley/Snell descendants that have had their DNA tested and have uploaded to Gedmatch.com for comparison
  • I never knew Holly looked so much like her Hartley/Snell grandmother.

Beth’s Hartley DNA

In this Blog, I will be looking at Beth’s autosomal DNA. That is the DNA that she got from both her parents. However, I am more interested in Beth’s father’s mother’s DNA as she was a Hartley and the DNA that we share would be Hartley DNA.

Hartley Tree of DNA Testers

Here are those closer relatives that have had their DNA tested and uploaded to Gedmatch.com:

Here Hartley is shown as green and Snells are shown as yellow. The DNA testers are in gold. Any DNA that the four DNA testers have in common will belong to James Hartley and Annie Snell. However, it will be difficult to tell which. Any DNA that Patricia and Beth share could also belong to Charles Nute which Jim and my family will not share. Here is an example of that on Chromosome 1.

Here is a photo believed to be Mary Hartley with her sister Nellie:

Hartley and Nute DNA On Chromosome 1

This is a Chromosome browser from Gedmatch.com showing where Beth shares DNA with Heidi (1), Joel (2), Sharon (3), Jim (4) and her first cousin Patricia (5). Is the DNA that Beth and Patricia share Hartley DNA or Nute DNA? To find that out we can look at Patricia’s DNA browser. If she shares DNA in this same area with Heidi and Jim, then it will be Hartley DNA.

The above Browser shows Patricia matching Beth (1), Jim (2) and Joel (3). This means that the DNA that first cousins Beth and Patricia share in Chromosome 1 is Nute DNA. If I were to map Patricia’s maternal Chromosome 1, it would probably look like this:

This shows that Patricia got her green DNA (matching Jim and me) from her Hartley maternal grandmother and her pink DNA (matching Beth) from her Nute maternal grandfather.

First Cousins Vs. Second Cousins

First cousins share two grandparent as their most recent common ancestor. Second cousins share two great grandparents and get their shared DNA from one of them. The first cousin DNA matches will be larger in general. The second cousin matches will tend to be smaller.

First cousins

As shown above, first cousins will share the DNA from two of their grandparents. In the case of Patricia and Beth, those two grandparents will be maternal grandparents. The catch is, that when two first cousins match each other, they won’t know which grandparent they match on. They just know that it will be one or the other. In the example above, we did know which grandparent matched because of other second cousin matches.

second cousins – Two common Great grandparents

Second cousins have as their most recent common ancestors two of their great grandparents. But again they won’t know which great grandparent they are matching on.

The best way to identify which great grandparent the gold people match on would be to have a third cousin that is only related on the Hartley side OR the Snell side. I don’t know of anyone in this category right now, so I’m a bit stuck. I would like to figure out which DNA is which. The main reason is that I’m stuck on the Hartley genealogy. I know that Greenwood’s father was Robert, but before that, I’m not sure. If we could find another Hartley relative going back then it might break down the Hartley brick wall.

Any Other Way To Separate Hartley DNA From Snell DNA?

There is one main difference from James Hartley and Annie Snell above as it relates to their DNA. James was born in Bacup, Lancashire, England and Annie was born in Rochester, Massachusetts. All of James ancestors would also have been born in Lancashire. On the other hand, all of Annie’s ancestors that would produce matches go back to Colonial Southeastern New England. That means that if we find a match that is from England and has no ancestors in the United States, there would be a good chance that that DNA match was through the James Hartley side.

Beth’s X Chromosome

First, let’s look at my family. There is  no Hartley X Chromosome sharing with this group because the X-DNA does not travel from father to son.

Second, look at Beth compared to Jim:

Beth got one of her X Chromosomes from her dad. This was the same X that he got from his mother Mary. Jim got an X Chromosome from his mother. She got it from James Hartley b. 1862 and Annie Snell. So Beth and Jim have James Hartley and Annie Snell in common.

These pieces of blue where Beth and Jim match represent DNA that they share from James Hartley and/or Annie Snell.

How do Patricia and Beth compare by X-DNA?

Next we will look at Patricia and Beth. They will share X-DNA with their grandmother Mary Hartley. Beth’s dad got no X-DNA from his Nute dad, so Beth and Patricia will only match on Mary Hartley.

Note here that Beth and Patricia share some X-DNA from their grandmother that isn’t shared between Jim and Beth on the left side. They also share a longer segment at the right hand side than Beth and Jim shared. However, Jim and Beth shared a segment from 123 to 138M that wasn’t shared between Patricia and Beth.

Let’s See How Patricia Compares With Jim

The only comparison left is between Patricia and Jim.

I compared the three comparisons and came up with a bit of an X Chromosome map. In the first match between Beth and Patricia, I have that match in red. On the very right there are three matches, so I have that as great grandparent 1. We don’t know which great grandparent it is – just that it is the same one. On Jim’s map, it is his grandparent 1. Going from right to left on Jim’s map, he changes from getting his X-DNA from grandparent 1 to grandparent 2. However, Patricia and Beth continue to match on great grandparent 1. In the middle there are no matches, so we can’t tell what is going on. Also the two reds and one blue on the left may actually be two blues and a red as we don’t know how they match with the segments on the right.

Beth’s Hartley (and Snell) Chromosome Map

If we look at all the matches Beth has with Jim, my siblings and me, we will have a map of her known Hartley (and Snell) DNA:

I didn’t use the DNA shared between Patricia and Beth as they are first cousins. As such, they will share Nute and Hartley DNA and it will not be as easy to tell which is which. So second cousins are good for these maps. The red is in the bottom part of each chromosome. That represents the paternal chromosome. We have not mapped any of Beth’s maternal chromosome. If Beth were to look for Hartley or Snell matches, it looks like her best bet would be on Chromosome 12.

For comparison, here is my Chromosome Map.

On my map, the blue corresponds to Beth’s red Hartley DNA. We seem to share a stretch of Hartley DNA on Chromosome 1. But where Beth has a long stretch of Hartley DNA on Chromosome 12, I have none.

 

Using M MacNeills Raw DNA Phasing Spreadsheet and My Problem Chromosome 10

I have written many blogs about phasing my own raw DNA. One of the things that was bothering me while going through the process was the presentation of the results. It is possible to phase millions of bases using the raw DNA results from one parent and at least 3 siblings. But once the DNA is phased, how can those results be best portrayed? In my previous Blog on the subject, I was able to figure out a fairly simple way to show my results, but the outcome was not totally satisfactory.

chr7patmatmap

I liked how I was able to get the grandparents’ surnames at least in the first 2 bars. I also liked how I had a simple scale at the bottom. However, one of my bars went too far. Also, my simple chart started at zero and Chromosomes start at different positions. I was able to fix the bar going too far today. Excel makes these bars based on distance rather than positions, so one of my equations was wrong.

I told M MacNeill <prairielad_genealogy@hotmail.com> of my concerns and he sent me his spreadsheet. One feature I really liked about the MacNeill Spreadsheet is that it had a place for cousin matches at the bottom. Below is the first Chromosome where I used my phased raw data from my mom and 3 other siblings to create a MacNeill Chart.

chromosome15macneill

Sharon’s maternal first little segment didn’t work out perfectly, but that didn’t bother me. I know that the beginning and ends of Chromosomes can have small problematic segments. Note at the bottom that my match to Carolyn in yellow shows where my maternal crossover is in the upper part of the chart where I go from red to orange.

My Chromosome 10

I am looking at my Chromosome 10 because, for one thing, I have had trouble trying to visually phase this Chromosome in the past. Here is my attempt at visual phasing from early in 2016:

chr10visphase

Here is another try including additional cousins that tested:

10r1visphase

Note how different the maternal (lower) side is. I switched most of the maternal grandparents around.

Here is the MacNeill spreadsheet showing just the cousin matching part:

cousinmatch10macneill

I have some good matches here. Blue is Hartley, green is Frazer, yellow is Lentz. Red is Rathfelder. This makes it clear that my chromosome is mapped wrong. I need more Hartley and Lentz. The above chart includes my brother who I had tested not too long ago.

Here is another try with my brother’s DNA results included:

10visphase3

My sister Sharon (S) has a better look now on her maternal side. I got rid of the small purple segment.

Looking At the Raw DNA Phasing – Paternal Side

I have two spreadsheet summarizing the results of the many hours of work it took to phase my family’s DNA  from the raw data. One spreadsheet is for the paternal side phased DNA and the other is maternal. I have patterns for both sides. They are based on the order of my siblings: me (Joel), Sharon, Heidi and Jonathan. So an ABBB pattern would mean that Sharon, Heidi, and Jonathan all get their DNA from one grandparent, and I get mine from the other. Here is the paternal spreadsheet:

dadpatternchr10

These patterns go logically one to the other. The first pattern goes from AABA to AAAA at position 2,605,158. The B changed to an A in Heidi position, so the crossover goes to her at that position. I have a column called GaptoNext. This is based on the number of tested SNPs between patterns. When this number is large, I suspect an AAAA pattern. That was the case above highlighted in yellow. Except there is a problem. To go from ABAB to AAAA means 2 changes, and there should only be one change (or crossover) at a time. This caused me to look at the bases.

A Paternal pattern missed

Here is what I found.

chr10patternmissed

I had missed an AABA pattern at Build 36 Position 30,683,878. I took another look by setting my MS Access query so that Sharon and Heidi would have a different base from Dad:

chr10rawpatterns

This shows that the there is a change from ABAB to AABA even sooner than I thought between ID 400008 and 400045. This is an ID I created that sequentially numbers the tested SNPs. You can see another way I missed this pattern, because I didn’t fill in the missing bases. TTC? should be TTCT. CCT? should be CCTC.

What does the missing pattern represent?

The pattern of ABAB TO AABA is actually my crossover (Joel). It is a bit more difficult to see than the others. That is because the ABAB pattern is the same as BABA. The change of BABA to AABA is my change of the first B to the first A. Naturally, I put myself in the first position. In rough terms, that gives me a paternal crossover at about position 30.5M. This is a good location as it does not interfere with a large match that I have with an unknown paternal DNA relative named Shamus:

shamus

Here is my corrected Dad Pattern for Chromosome 10:

dadpatternchr10corrected

I have gone from 6 to 8 crossovers as the previous correction lead to another one. I also took out one of Heidi’s crossovers that I had wrongly identified. So fixing one problem fixed a lot of others. It helps to describe the start and stop of each pattern and to describe each crossover. The important results are the person and the last Position column. These show who the crossover belongs to and where that crossover occurs on the chromosome. I then entered the paternal crossover results into the MacNeill Spreadsheet and got this:

patchr10chart

I took out the large space between the siblings. The problem is that the space is now the same as between the maternal and paternal phased part for each sibling. Excel has no happy medium that I’ve found.

The blue is Hartley and green is Frazer. The raw phasing in the upper part of the chart matches with the cousin matches below. It is interesting that some of the cousin matches define the crossovers. For example, the Jim to Sharon match gives Sharon’s crossover. Also the Paul to Sharon match gives Sharon’s other crossover. The Paul to Jonathan match gives Jon’s first crossover.

The Maternal Side

Hopefully resolving the maternal phasing will be easier than the paternal side. My visual phasing only showed four crossovers. Here is my unfinished spreadsheet showing 5 crossovers (under the Person column):

maternalchr10

Here, it looks like I already added an AAAA pattern to the end. That was because the AABA pattern ended at about 114M and the Chromosome itself ends at about 135M. My GapstoNext column showed that gap as almost 20,000 SNPs. My question now is: should I add an AAAA pattern to the beginning also? Perhaps. An AAAA pattern means that 4 siblings match and all got their DNA in that area from their maternal (in this case) grandmother. Those results were consistent with how I had the visual phasing done. In fact, the visual phasing indicated that the 4 siblings should all get their maternal DNA from the Lentz side up until about 60M. Let’s take a closer look. This gets at my first note above in the spreadsheet image. There were only 3 single SNPs showing the AAAB pattern and they were spaced a long way apart – over 10 Megabases each. In this case, I will disregard those 3 widely spaced patterns as some type of mistake and stay with the AAAA pattern. Once I made the change from the AAAA pattern to the AAAB pattern, that brings us up to about 60M for my (Joel’s) first crossover. That seems to fit well. That leaves us with 4 crossovers – one per sibling as opposed to the two per sibling on the paternal side.

First I’ll compact the Gedmatch browser results, then show the raw DNA Phasing results on the MacNeill Chart:

gedmatchcheckofrawphase

chr10phasemap

When I compare the results, I see a problem I had with the visual phasing. The next to the last crossover looked to belong to Sharon, but instead it belonged to Heidi. Also Jon’s second paternal crossover should have been marked as an “F” above. That was just a typo. The third J for Joel crossover that I had above was not a crossover. In the middle, the 2 close crossovers of J and S should be instead S and J if I’m reading the MacNeill Chart correctly. It looks like all the FIRs and HIRs, etc. match. Once I did the raw DNA phasing, it is obvious how the gedmatch browser results had to match the raw DNA phasing results. Before, I did the raw DNA phasing it was not so obvious.

I’m happy with the results. I get to pick whatever colors I want for the four grandparents. It still would be nice to have some sort of labels or color key. After a hard day of phasing DNA, it is rewarding to see the results displayed so nicely. Thank you Mr. MacNeill.

A few observations:

  • The 4 siblings did not inherit any Rathfelder DNA (brown) on the left side of Chromosome 10
  • Lentz DNA (yellow) is missing from the right side of the Chromosome for the same 4 siblings
  • As I have my mother’s DNA results, that would make up for the missing DNA from those 2 maternal grandparents
  • Short segments of Hartley DNA (blue) are missing near the beginning and near the end of the Chromosome (i.e. none of the four siblings inherited Hartley grandfather DNA in those areas).

Summary

  • M MacNeill has the best display that I am aware of for mapping phased DNA.
  • The final mapping is like the final exam where previous mistakes are brought out, but there is a chance to correct them.
  • The phasing process is difficult, but there are built in checks and balances to find and correct mistakes or missed patterns.
  • The raw DNA phasing procedure (I use the Athey method) would generally be used if a parent has been tested and the visual one is used if a parent has not been tested. However, the visual phasing as developed by Kathy Johnston is important to use as a framework for the raw DNA phasing as well as a check for the end result.
  • The raw DNA phasing results appear to be better than what I was able to get using the visual phasing. Not because the visual phasing method is bad; more because I have not mastered it.
  • If you are using someone else’s spreadsheet, it is a good idea to know how they work in case anything goes wrong.
  • After writing many blogs on visual and raw data DNA phasing, it is nice to see everything come together using the MacNeill Spreadsheets and Charts.

DNA Phasing of Raw DNA When One Sibling is Missing: Part 10

In this Blog, I would like to portray my phasing results in an Excel Bar Chart if possible. This has been one of the most difficult parts a phasing my DNA for me.

I have looked at Stacked Bar Charts in Excel as they seem to be the closest to what I am looking for. Today I looked at a method for producing Gantt Charts at ablebits.com which seems to hold some promise of application for DNA mapping:

bar-chart-excel

I had my Maternal Patterns’ Starts and Stops from my last blog. I took those and converted them to Build 36 and put them in a spreadsheet:

momcrossoverstable

Start is the ID# I was using. Start36 is the Chromosome position of the Start of the pattern in Build 36. App ID is the approximate position of the Crossover. Then I have that same location in Build 37 and Build 36. Following the logic in the Ablebits.com tutorial, I have the first Maternal Crossovers for Chromosome 7 in my simplified Chart:

matfirstxover7

I got this by choosing the Build 36 column and choosing Insert Stacked Bar. I suppose a better Title would have been Chromosome 7 Maternal Crossover rather than Build 36. This was taken from my Column Header. The goal is to get a 2 color bar above. However, I already see a problem. The bar needs to be different colors for different people. Well, I have to start somewhere.

Next, I put in the next crossover location for each person. I took this position and subtracted from it the first Crossover to get a length.

step2crossexcel

You may note that the Bar Chart inverts the original order. It gives Sharon a 4 which is now on top. Here is my visual phasing of Chromosome 7 that I am trying to replicate:

chr7visphase

My Excel Bar Chart order is Sharon, Jon, Joel, Heidi. My visual phasing order is Sharon, Joel, Heidi, Jon. The 2 maternal colors I have above are green and orange representing Lentz and Rathfelder. If I keep orange as Rathfelder, that means I want to change bar 2 and 3 (Joel and Jon) on the Excel Bar Chart. One way to do this is to move over the first Crossovers for Joel and Jon in my spreadsheet:

modchart

However, that made the 2 male siblings’ first maternal grandparent match too long. I needed to move the start over 2 places in my spreadsheet:

mat7revised

Now the Chr7 Maternal Crossover column can be called Lentz and the 2length column can be called Rathfelder.

Next, I added another column for the next Lentz portion of DNA:

chr73rdxover

I was hoping that if I named the next column Lentz, that Excel would give me the same blue as the first Lentz. I was able to right click on the gray and change it to blue. I then added another Rathfelder segment. For this to work in Excel, a Rathfelder length is added rather than a start and stop location.

chr7xover3

Again, I had to reformat the Excel-chosen color to be consistent with what I had for Rathfelder. I chose the last position for Heidi and Sharon as the highest that I had as this was their last segment. After a bit of wrangling with Excel, I was able to get this:

chr7

So that is the presentation. However, I notice that on my visual phasing, I had 5 segments for Jon and only 4 here. I missed his last Rathfelder segment. I had ended Jon’s Chromosome too early. Here is the correction:

chr7corrected

It still looks like one of Jon’s crossovers in the middle of the Chromosome may be off, but I’ll have to figure that out later.

Paternal Bar Chart

Now that I have something that looks like a maternal Chromosome Map, I need the paternal side to go along with it. It looks like if I add 4 more rows to my spreadsheet, I may have it.

I did this and I added Hartley and Frazer (my paternal side grandparents) to the right of the maternal side grandparents. I had to make a new chart that came out like this:

chr7matpat

Here #4 is my Paternal DNA. I found it a bit disconcerting that my paternal side was longer than the maternal. Here I’ve added a bit of formatting and made the colors consistent (one color per grandparent):

chr7patmatmap

Well, I guess I’ll just leave this imperfect. It will give me something to work on later. I did change the scale from millions to M’s to be easier to read.  The above shows that Jon and Heidi share their paternal grandfather’s Hartley DNA un-recombined on Chromosome 7.

Summary and Conclusions

  • Learning how to phase my raw DNA has been interesting and time consuming
  • Delving into the A’s, G’s, T’s and C’s promotes understanding of one’s DNA
  • I owe a lot to M MacNeill and Whit Athey in learning how to do this phasing
  • Due to the data intensive nature of phasing, I would recommend the use of MS Access or some other database software.
  • An understanding of Excel or similar spreadsheet software is also important.
  • I had tested my brother Jon as an afterthought. It turned out that his test results were important in determining the phasing of the 4 siblings.
  • I have the overall skeleton of the phasing with crossovers. There is still a lot of work to complete the individual Chromosomes and trouble shoot problem areas.
  • Further, I have not worked on the X Chromosome due to the different nature of that Chromosome. My brother and I are already phased. My sisters are not.
  • Once these maps are done they will be a reference to all matches to my 3 siblings and myself.

Raw Data Phasing Part 4: Going from 3 Siblings to 4

In my last Blog, I mentioned that my brother Jon’s DNA test results came in this week. This happened in the middle of my attempt learn how to phase the raw DNA data for my 2 sisters and myself. I was phasing the data in what I can only assume is a traditional way. I say I assume, as I haven’t seen any other blogs on the process. The difference is that I am using MS Access which I hope will speed up the process. I should be able to get results for 23 chromosomes at a time instead of just one at a time.

The arrival of the new DNA results poses at least two problems:

  • The previous 4 DNA data files were all in AncestryDNA version 1. Jon’s is in AncestryDNA2. While they are all Build 37, they look at somewhat different points on the chromosomes
  • One of the difficult parts of the previous process was identifying and dealing with patterns of phased paternal and maternal bases. Those patterns were AAB, AAB, and ABB. With 4 siblings, there will be more patterns. However, the Whit Athey Paper I have been following does also look at 4 siblings.

AncestestryDNA Version 1 Vs. AncestryDNA Version 2

My understanding is that Ancestry changed the locations on the chromosomes that they were testing to get more into the medical area like 23andme. I don’t know if that is true. Here is a chart comparing the different atDNA tests:

ancestrydna-compared

I was doing well comparing Anc1 with Anc1 as I was looking at over 700,000 base pairs among 4 people. Once I compare Anc2 to Anc1, that is number is cut down quite a bit. That is about a 40% drop. My only other option, other than re-testing Jon, is to compare Jon to my mother’s FTDNA results. However, that will only pick up 2-3,000 SNPs, so I won’t bother.

Back to Square One with 4 Siblings: Homozygous Siblings

I need to find Jon’s equal base pairs and apply one to his ‘from dad’ column and one to his ‘from mom’ column. That is, after I add all Jon’s data to my database and add those columns. First I need to decide where to add Jon’s data. I could add it to the beginning of what I have already done or to the end. I’ll try adding it to the end, because I think that the work I did already is OK. I want to build on that. So rather than adding Jon’s DNA to the first step, I’ll add it to my table called tblMomBaseFromDadBase. This table has over 700,000 lines of bases for 4 people. Jon’s has 668,942 lines. Actually, when I remove “Chromosomes” 24-26, I will only have 666,531 lines.

Querying Jon into my latest table

Here I am adding Jon and the Mom from Dad Table to my query design:

adding-jon

Access thinks the ID that it added was important, but it really isn’t, so I need to take out that equal join. I really want the join to be at the rsid, but I don’t want an equal join. Why not? If I had an equal join, I would end up only with the positions that Jon has. I will lose 40% of the work that I have already done. Instead, I’ll use an unequal join.

unequal-join

I flipped the 2 tables in the query design area, so things are moving left to right. Then I choose a #2 join which is basically, an unequal join left to right.

Actually, I changed my mind. I have a better idea. I will just do the first 2 steps on Jon’s raw DNA and then join the results together. That is a third way that I hadn’t thought of. The point is, that there are many ways to do things in Access. There can be more than one way to get to where you want to be.

Back to Homozygous Siblings

First I copied Jon’s raw data into a table called tblJonHeterozygousSib. This is so I can use an update query to update the data in the new table and still have the original. Hold that idea. The better idea is to use a make table query. The reason that this is better is that it can take out the “chromosomes” I don’t want:

make-table-query-jon

I took out the table I copied and I’ll make a better one with only Chromosomes 1-23. I hit the Run button and create a table with 666,000 lines:

jonhomosib

Then in the above table, I inserted 2 rows: JonFromDad and JonFromMom. Now this table is ready to phase for any homozygous siblings. By the way, it looks like my Chr23 or X is homozygous, but it isn’t. Ancestry adds an extra base. I only really have one for my X Chromosome.

Finally time to query and phase

I go to Query Design in Access and choose the above table. This is a very simple Update Query design:

qrysibhomojon

This says if Jon’s allele1 is the same as his allele 2, put allele 2 as his base from mom and as his base from dad. I hit the run button for the update and get the dire warning that I’m updating a lot of information, I can never change it back. Then I get a message that I’m updating 478,000+ rows. That is good. Those are the number of Jon’s homozygous bases – quite a few. I’d say over two thirds.

I’m not looking for crazy results and didn’t get any.

Homozygous Mom Query

I’ll copy my previous table into one to update. Then I need to add Jon’s base from mom where mom is homozygous. Easy peasy. I think this is all I need.

momhomoupdatequery

Actually, I did think of an issue. I have an equal join. That means I won’t be using the homozygous bases that mom tested for in the old AncestryDNA test that aren’t in the new AncestryDNA test list. My guess is that is interesting information but perhaps not very useful. It also occurs to me that in the spots where Jon doesn’t match up with my siblings, I will still have the 3 letter pattern work that I had done previously.

The query above says if Mom allele 1 = 2, then put that 2 allele in Jon’s from Mom base slot. I hit Run and pasted 277,000 rows of bases.

homomomforjonresults

This query will be a little more difficult to check. I have to create a query linking my mom’s DNA results to this table. I did that and see one problem already.

momrawtojonfrommom

The first problem is that ID 126 didn’t show up. That means that rs3819001 that Jon has is not in my mom’s raw DNA. I don’t want to have data for Jon that looks like it can be updated, but it can’t.

I think I can fix this.

Updated Table Query

A few steps ago, I ran a Table Query to get just Chromosomes 1-23 into Jon’s Table. I need to upgrade that query so that I am only including the locations (rsid’s) that are common to both my mother and Jon. I do this using an equal join on the rsid Field:

updatedtablequeryforjon

This time, my table for Jon only has the rsid’s that my mom has.

newtable-upda

Also my Chromosome formula was off, so I had to fix it. Also note that I have about the number of rows as per my Anc1 vs. Anc2 table earlier in the Blog. I then re-added the Jon from Dad and Mom columns into the new and improved table. Then I reran the update query which told me I was about to update 284,000+ rows.

homozgygousjonupdate

This worked as well as last time, but this time I have the fewer rows I was trying to get.

Re-Run the update query for homozygous mom for jon

I double clicked on my old update query. The message said I was updating 277,000 rows or so. Now I’ll re-check my work. If there is no ID 126, I’ll be happy. Well it is still there, because I forgot to copy the previous homozygous sibling table into the homozygous mom table. After re-re-running the update, I got the desired results:

tableno126

And there you [don’t] have it: no ID 126. Here is my mom’s raw file compared to Jon’s updated table.

momrawtojonfrommom

Jon gets a G from mom at ID 128 even though Jon is AG, because mom is GG. Now I’m talking DNA.

Merge Jon’s New Table with His 3 Siblings’ Tables

This is the point where I put everything together. I will try to use the Make Table Query for this one again. So I’ll put my newest Jon table together with my newest sibling table.

left-to-right-merge

This shows the left to right arrow join. I’ll want the larger file plus everything equal in the smaller file. Come to think of it, this Create Table Query would have fixed the earlier problem I had. I guess I was too careful! The other issue is that the ID in the 1st table won’t be the ID in the second table. I could keep the second ID, but I would have to rename it as Jon ID or Anc2ID.

newidtablemerge

 

Here I rename Jon’s IDs as JonID. I may not need it, but if I do need it I will have it. I guess MS Access wasn’t happy with my idea:

autonumber

OK, I took out the JonID and hit Run. Microsoft tells me about my new 700,000 row table.

Back to the Dad Patterns

Now that all the family is together I want to look at Dad Patterns, because I know that I will be updating those. Here is the first query I tried on my new Table of 4Sibs.

sharon-not-joel

This is looking for filled in Dad bases where Sharon’s base is not the same as Joel’s. That query gives me an ABAA pattern:

abaa-pattern

Also ABBB:

abbb

Here’s ABBA:

abba

It looks like ABAB is a possibility also. That means the following are possible:

  • AAAB
  • AABA
  • AABB
  • ABAA
  • ABAB
  • ABBA
  • ABBB

So if I chose Joel’s Base not equal to Sharon and then Joel’s base equal to Sharon would I have every combination? It looks like I need this combination to cover all possibilities:

  • Joel <> Sharon OR
  • Joel<>Heidi OR
  • Sharion<>Heidi OR
  • Heidi<>Jon OR
  • Jon<>Joel OR
  • Jon<>Sharon OR

Which in Access looks like:

access-pattern-combos

But Wait, I Forgot Principle 3 for Jon

Principle 3 says where Jon is heterozygous and he knows where he got his maternal base, the other base goes into his From Dad column. Looking back at my old queries, I see this is a 2 step query. I’m tempted to try this in one step, but I think  this got me in trouble before, so I’ll go with the simpler query. Simpler queries are usually better in MS Access.

jonhetero

This says where Jon is missing a phased allele from Dad and he has an allele that doesn’t equal the one he got from mom (making Jon heterozygous here) put that allele into Jon’s From Dad spot. I tried the query and only got 37 results. The problem is, I should have said ‘Is Null’ in the JonFromDad Criteria:

jonheteroisnull

This time I get 35,000 updates, so that is right. I then change the allele1’s to allele2’s above and get 33,000 updates to tbl4Sibs. I ran a quick query on the 4Sibs Table to get just Jons heterozygous results:

jonheterocheck

In the first line, Jon had allele1 as T which was different from the allele from Mom of G, so Jon’s T got put into the From Dad spot. At ID 41, Jon’s allele2 of G is from Dad because he had an A from Mom. When parent and child are heterozygous, the From Parent location remains blank.

Now I have Jon with 3 Principals: Homozygous Jon, Homozygous Mom and Heterozygous Jon.

Back to Dad Patterns

I have the old Dad Patterns for 3 siblings. Now I need to See what the 4 sibling Dad Patterns would be and add Jon’s Start and Stop Locations for his new Dad Pattern Areas. I need to combine that with the 3Sibs Table.

wrongpattern-query

My first query was wrong and gave bad results. The reason is that the ID for 4Sibs was from the raw data. The ID for the Dad Pattern Table just numbered the amount of Dad patterns. I needed to join the ID in the first table to the start and stop locations in the second table. I ended up doing 2 queries: one for the start position and one for the stop as I needed both. This query gives the stop position of a pattern.

stop-query

I took both those queries and put them into an Excel Spreadsheet.

excelstartstopfromaccessdad

I added a new column called Dad4Pattern. In the first row, the new pattern was AAA by chance. However, in the second row which is the Stop or End of the first Dad Pattern, it is obvious that the ABA Dad Pattern goes to an ABAA Pattern. I didn’t think that there would be many AAAA Patterns as that means that all siblings match the same Paternal grandparent. This is the only AAA pattern that I had noted so far as I wasn’t looking for them yet. Still, I will need to go back and verify that these Start and Stop AAAA’s were not by chance. Finally, on the last line, it is clear that the Dad Pattern goes from AAB to AABB with Jon added.

Next I chose all the cells where Jon had a base from Dad and performed a Concatenate operation to write the pattern.

concaternate

This gave me the CCCC that I wanted to check. Next, I wrote a formula to put the Dad bases together in a new column and wrote down the Dad Patterns that I had.

newdadpattern

A few notes:

  • Out of the 66 three sibling patterns that I had, I was able to find all but 5 new four sibling Dad Patterns. See the yellow above for two of the missing 4 sibling dad patterns.
  • The missing 4 sibling dad patterns should be easy to find by scrolling through the 4Sib Table
  • I noticed that there were no AAAB patterns. That is because in my previous search, I was not looking for AAA patterns. So now, I don’t have any AAAB patterns. I will have to find these in my new search.
  • AAAB is the situation where I match the same paternal grandparent as my 2 sisters, but Jon matches the other paternal grandparent.
Filling in more dad patterns

To fill in the yellow areas, I made a query in Access based on the 4Sibs Table. This looked at every case where Jon had a base from Dad. Searching around the ID 6604 and after, I found this pattern:

fill-in-patterns

ABBB

Then I checked near the end of the old 3 sibling pattern which is at ID 19806.

break-point

At ID 19827 we see an ABAB Pattern, so I enter that Pattern in my spreadsheet:

newpattern4

For the start of the new ABAB pattern, I used the old ABA location as that was more precise. The next interesting thing happens at Chromosome 2:

chr2

Here I have a problem in my spreadsheet. For some reason, the Start of the last pattern of Chromosome 2 ends at Chromsome 3, which is not right. My previous spreadsheet was better than that. From the ashes I will re-build.

I note that at ID 108798, my 4 Sib Spreadsheet goes to an ABAB Pattern. At the end of Chromosome 2, I see an AAAB Pattern. That was the one I wouldn’t have had from the 3 sibling pattern as I wasn’t checking on AAA’s.

I added new rows for the patterns ABAB and AAAB:

addnewrows

The most important thing here is the ID, the pattern, the Start and Stop. Here is the new change area from ABAB to AAAB:

chr2change

There are a few SNPs between the ABAB Stop and the AAAB Start that are a little unclear.

end-of-2

Finding Jon’s Patterns

Now I’ll check Jon’s Patterns. I’m looking for any changes in patterns as these should be important as crossovers later. I will need to assign the crossovers to each sibling’s Chromosome Map.

Good Old Triple A – B Pattern and all the others

AAAB is where Jon has a different paternal grandparent than his 3 tested siblings and the 3 siblings have the same paternal grandparent.

aaabquery

My query says that Jon has to be different from each sibling. I run that and insert the appropriate Start and Stop point for the AAAB in my spreadsheet.

I do the same for AABA which I can find using a similar query under Heidi’s criteria:

aaba-query

I ended up going to a clean spreadsheet. It was too messy combining the 4 sibling results with the old 3 sibling results.

4sibpatterns

Here I have the ID, the Chromosome, the pattern and the Start and Stop. The yellow marks a one SNP pattern. It appears that there should be 3 types of patterns:

  1. One where one sibling matches none of the others. That is what I have above: AAAB, ABAA, AABA and BAAA
  2. One where 2 pairs of siblings match each other: AABB or ABBA. I’m not sure what else there could be. I looked above and saw one other: ABAB
  3. One where all the siblings match each other: AAAA

That makes 7 or 8 patterns, depending on whether AAAA is considered a pattern.

Two Pairs of siblings match each other patterns

Here is the Access query for AABB

aabb-query

At first I was missing the criteria under SharonFromDad and that gave me AAAA combinations also. The result of the query looks like this:

aabb-results

Here Joel matches Sharon and Heidi matches Jon but on a different base. After I was finished putting in Starts and Stops for each Pattern, I then sorted my spreadsheet by ID. This brings up some issues that need looking at:

quality-control

Where there are 2 Starts or Stops in a row, there is a need to check what is going on. The ones around the yellow positions may not be a problem as I’ll likely be taking those single positions out. However, at the end of Chromosome, there are 2 starts and 2 stops together. I need to go to ID 236707 and see what is before that point. It apears that there is an AAAA pattern before that point and that the ABAB at 224584 is a single point. That fixes half of the problem. Then I go to ID 238976 to see why I have a Stop there for ABAB.

fix5

I had missed the Start for the ABAB right after the stop of the ABBA pattern, so I added it in. The repaired spreadsheet looks like this.

fix5spreadsheet

An application

Now that I have the change between ABBB and ABAB described, let’s look at what it means. Here is a different look at that location:

heidi-break

When the pattern changes from ABBB to ABAB, what has changed is the third B changes to an A. Heidi is in that location. So that says at the above position of Chromosome 5, Heidi has a paternal crossover. I thought it would be good to check my work against the work of M MacNeill. To do that, I used the NCBI Remap website to change my Build 37 results to Build 36:

remap

This would be the start of Heidi’s new segment. Here is what MacNeill had:

macneill-check

I got it right again. That is 2 for 2. Actually, the first time I tried, I was comparing the wrong Chromosomes. Rookie mistake. Here is M MacNeill’s map for Heidi on Chromosome 5:

macneill5

Perhaps it is difficult to see, but the point I am looking at is the little lighter red segment at the far right of Chromosome 5. Perhaps that is why I missed it the first time as it is so small.

Another Aside is that this was a very difficult Chromosome to decipher using visual methods. This was one of my attempts to figure out the crossovers visually for 3 siblings.

visual-chr5

I had missed the last crossover as it is so small and difficult to see. In my defense, I should note that M MacNeill did mention that the end of this Chromosome was difficult to decipher.

Taking Out the X

I’ve realized that I’ve generated some bases for the X I got from Dad. Of course, I didn’t really, so I’m taking out any bases there for me and my brother Jon. I’ll use this update query:

takeoutx

I was worried that I’d mess something up, so I created  a  new table called 4SibsChrX. My query put dashes in the spots where I couldn’t have an X base from Dad:

xtodash

This looks like a good place to end Part 4. It appears that there should be many chances to quality check my work and that the process is progressing. Getting Jon’s new DNA set me back a bit, but the results should be better than what I’d see with 3 siblings.

 

Raw Data Phasing: Part 3

This Blog is Part 3 documenting my learning process of phasing my DNA raw data using:

Part 1 and 2 Recap

  1. I imported 4 sets of raw data into Access from AncestryDNA after taking out the zeros that the Excel software produced for the no-calls.
  2. I used Access Queries to apply 3 Whit Athey Principles. This resulted in many phased bases for me and my 2 sisters.
  3. I put the phased A’s, G’s, C’s and T’s for each siblings into 2 new columns for each sibling
  4. This resulted in 6 new columns. The first 3 of these six were for the paternally based bases. These resulted in a pattern which was either in the form of AAB, ABA, or ABB.
  5. The Athey Paper did not emphasize the AAA pattern or considered it a non-pattern. While specific AAA results within another pattern area are by chance, there are other areas where 3 siblings match the same grandparent where there will be an AAA-only Pattern.
  6. I separated my results into 3 patterns using Access: AAB, ABA, and ABB
  7. For each of those results, I noted where those patterns changed.  I did this by looking at the ID numbers. Breaks in the ID numbers were considered changes.
  8. However, there were some cases where the changes occurred around missing bases. For these, I went back and noted a more precise position of the pattern change based on where the change would be if the missing base were to be filled in.
  9. I Made a preliminary bar graph using the first 3 paternal changes. These crossovers were mapped to myself and 2 sisters.
  10. Using the 3 patterns I developed Access queries to fill in the missing bases in the 3 paternal pattern areas.

So those were the 10 easy steps. Actually step 10 was difficult as there was quite a bit of refining the Access queries and quality checking the results. I needed 2 queries for each of the pattern areas. However, once I had the queries, it was the push of a button to update missing parental-received bases for 3 siblings within over 700,000 lines of DNA.

Back to Athey

This portion of the Athey Paper appears to apply to where I am now:

For some of the unfilled cells on the mother’s side of the table, we can fill in the alternative (other) base from the corresponding location on the father’s side of the table. That is, we know that the sibling with an empty cell got one base from the father, but the alternative base from the mother. Therefore, after the use of the Dad pattern fills in more cells, a newly filled – in cell in the father’s side of the table gives rise to a filled – in cell in the same position on the mother’s side–the alternative base to what was on the father’s side.

Unfortunately, I’m not sure what is meant above. My guess is that this relates to Principle 3:

Principle 3 — A final phasing principle is almost trivial, but it is normally not useful because there is usually no way to satisfy its conditions: If a child is heterozygous at a particular SNP, and if it is possible to determine which parent contributed one of the bases, then the other parent necessarily contributed the other (or alternate) base. This principle will be very useful in the present approach.

So now that missing paternal bases have been determined based on the patterns, it should be possible to fill in missing maternal bases for heterozygous children. First, I’ll do a Query to see if I can locate this situation. I’ll take my most recently updated Dad ABB Pattern Table update and query that. I’ll look at the situation where there are heterozygous results. Then, I’ll look at spots where there are missing bases from Mom.

Fortunately, I was able to come up with a slick looking Query for this situation:

mom-from-dad

Plus the Query design has some nice symmetry. The first criteria row of the query is for my (Joel) DNA. Reading across, it says Joel is heterozygous because my allele 1 does not equal my allele 2. Then it says that I have a base from Dad but not from Mom. This will show areas where the mom bases are missing in this heterozygous child situation.

mom-bases-to-fill-in

The truncated fields above are Joel Allele 1, Joel Allele 2, Sharon allele 1&2, Heidi allele 1&2. The next 3 columns are Joel, Sharon and Heidi from Dad. Then Joel, Sharon and Heidi from Mom (the last 3 columns). This shows that there are almost 12,000 of these Mom bases to fill in. Above the blue line are Heidi’s bases missing from Mom. Heidi is TC (heterozygous) on that line. Her Dad base is T. I love these binary problems. They seem well suited for the computer. That means that a query could not be too difficult to update almost 12,000 records. So Heidi’s Mom base will be C above the blue line. At the blue highlighted area, I am TC and my Dad base is C. My Mom base will be T on the blue line.

Looking for a Good Query to Fill In Mom Bases from Dad Bases

First, I copied my ABB Table to a new Table called tbleMomBaseFromDadBase. I will want to update that table with a new Update Query. I already have the first part of the query. Now I need my thinking cap. Even better than thinking, I can look at what I did before. Here is my old query.

allele1-query-heterozygous

This is difficult to see, but I split the problem into 2 alleles. What this says is when Sharon has a base from her mom and Sharon’s allele 1 is not the same as the base from her Mom, pop that allele 1 into her base from Dad slot.

For our situation we are doing the opposite. So we will switch Mom and Dad. This time we are using our Dad results to get some Mom results. I’ll also add a criteria to make sure the Mom result is Null, so I’m not overwriting anything. It will just be an extra precaution.

Basically, I want to make sure Heidi has a base from Dad and not from Mom. In that case, when her allele1 is not equal to her base from Dad, put that allele 1 in as her base from Mom. Drawing upon my vast experience in this area of about 1 week, I get this:

allele1dad-to-mom

When I preview the results, I get about 6,000 lines which is half of my previous query, so that seems OK. I’ll go ahead and update my new Table. I renamed my Query to qryMomBaseFromDadBaseAllele1 and copied it to do the same thing with Allele2. I’ll change the Allele’s 1’s to Allele’s 2 in the Query design. First I’ll do a Select (non-updating) Query to show what I’ll be updating with the allele’s 2.

allele2momfromdadselectquery

Here I added the ID numbers, so I can make sure my update went well.

Here is my Allele2 Update Query with the 3 siblings included:

allele2momfromdadupdatequery

The results:

momfromdadupdate

In the far right column is the Base Heidi got from Mom. It was updated on lines 2292, 2295 and 2299. In each case Heidi’s Paternal Base was T and the Maternally derived Base from Dad was C.

Here is my corresponding filled in Mom Base:

joelmomfromdad

My Dad’s T’s in 6 columns from the right were used to fill in the missing C’s in 3 columns from the right. Doesn’t it seem a bit ironic? Even though my dad was not tested for DNA, his “results” from this process are used to find the DNA I got from my mom who was tested.

A Premature End to This Blog and a New Beginning

This will be one of my shortest Blogs. I was both awaiting and not awaiting my brother’s DNA test results. Those results came in this week. The reason I was not awaiting was that I knew that I would need to re-start the raw data DNA phasing process once his results came in. With that, I’ll end this Blog and start a new one.
