Visual Phasing: My Father in Law’s Chromosome 22

Looking through the visual phasing of my father in law’s family, I notice I am missing a map for Chromosome 22. Chromosome 22 is the easiest and hardest Chromosome to visually phase. It should be the easiest because it is the shortest Chromosome and should have the fewest number of crossovers. It should be the most difficult because it should have the fewest cousins matches. I assume that I haven’t visually phased Chromosome 22 because of the hard part.

Gedmatch One to One Comparisons

To do visual phasing, I need to compare my late father in law Richard to his two sisters in the Gedmatch Chromosome browser. Here is how Richard matches one of his sisters, Lorraine:

This shows that Richard matches his sister Lorraine all along the Chromosome except for a little segment between 43.6M and 43.8M. Hopefully this is accurate. Other comparisons should bear this out. By comparing siblings, we are looking at how many grandparents’ DNA they share. Green means that Richard and Lorraine share two grandparents’ DNA. More specifically, they share one maternal grandparent and one paternal grandparent.

Yellow means they share one grandparent on a maternal or paternal Chromosome and don’t share the grandparent on the opposite Chromosome. For example, if they share the DNA from a maternal grandparent, that means that they don’t share DNA from the same grandparent on the paternal Chromosome. This is all important information for visual phasing.

Finally, above the break in the solid blue line above is a red area. That means that in that little segment, Richard and Lorraine share DNA from neither of their grandparents. This is important information. Richard’s paternal grandparents are Butler and Kerivan. His maternal grandparents are LeFevre and Pouliot. So say Richard gets his DNA from Butler and LeFevre in that red area. That means that Lorraine must get her DNA from Kerivan and Pouliot in the red area. Those are the rules for Visual Phasing.

Next I put the three comparisons into Excel.

Then I look for changes in the colors on the Chromosome Browser. These changes should come in pairs. The first two changes are in the first two bars. The colors go from green to yellow. That means that the shared DNA goes from two grandparents to one. Lorraine’s name is associated with both those comparisons, so we say that Lorraine has a crossover there. A crossover is where Lorraine’s DNA changes. Before the crossover, she is getting DNA from one grandparent, and after the crossover, she is getting her DNA from another grandparent.

Again, these crossovers show up in pairs. A top/top pair assigns the crossover to Lorraine. A top/bottom pair goes to Richard. A bottom/bottom pair of changes assigns the crossover to Virginia. Above, Lorraine and Virginia got 2 crossovers each and Richard got three crossovers.

Next, I show the two Chromosomes that everyone has – in this case for Chromosome 22. Unfortunately, I don’t know which side is maternal and which side is paternal at this point.

These two copies of Chromosome 22 are blank for each sibling right now, but I’ll fill them in with four colors representing the DNA they got from each of their 4 grandparents. When the DNA changes from Butler to Kerivan on the paternal copy, for example, that is where the crossover is for a particular sibling.

Visual Phasing

Richard and Lorraine share a large green area. That means that they got the same DNA from one grandparent on the maternal side and the same DNA from one grandparent on the paternal side. The DNA from those two shared grandparents will be represented by two colors.

The blue and orange colors represent the DNA that Richard and Lorraine both share from the same grandparents: the same maternal grandparent and the same paternal grandparent. Unfortunately, I don’t know which side is maternal or paternal at this point and which grandparents they share. I just know they share the same grandparents.

Note also that Richard has a crossover at the beginning and end of this colored-in segment. We don’t know if his crossovers are on his maternal Chromosome 22 or paternal Chromosome 22 – or it could be that one crossover is maternal and one is paternal. That means that we will keep his blue and orange segments where they are – for now. However, Lorraine’s first crossover is to the left of the green shared area. That means her blue and orange DNA segments can move to her first crossover. The same segments can also be moved to the right up to Lorraine’s next crossover. No crossover means no change in the DNA.

This show that Lorraine got two pretty long segments of DNA. Let’s say she got them from Grandparents A and C.

Next we need more grandparents. We only have two out of the four. In the middle of Chromosome 22, notice that Lorraine and Virginia have no match. There is a large break in the dark blue line. That means that in that area, If Lorraine has DNA from Grandparents A and C, Virginia has DNA from grandparents B and D. Now we need two different colors:

To check notice that Richard and Virginia also have no match in a smaller area, therefor they also show two different colors in that area. Virginia has the last crossover, so I move the brown and green segments to that crossover.

Richard and Virginia have a smaller green area starting at position 43.8.

Richard has no crossover that prevent the brown and green segments from going to the end of Chromosome 22. That is as far as we can go with the bright green areas (which are also called Fully Identical Regions or FIRs) and the red non-matching areas. At this point we could look at the yellow areas which are also called Half Identical Regions or HIRs. Or we could look at cousin matches to see if they give any hints. I’ll look at cousin matches.

Cousin Matches

A first cousin should sort out the maternal or paternal side. I pulled up Virginia’s spreadsheet where I have a lot of her matches. On Chromosome 22, I notice 2 of Virginia’s maternal 1st cousins, Joe and Pat:

 

In Virginia’s spreadsheet, I have these positions in pink for Virginia’s maternal side. Next, I checked out some of the matches at Gedmatch and got this:

Here, #1 is John, a nephew. Nephews are not as helpful as they can be related on the maternal or paternal side. Note also that something seems to be going on around 25.4 M. This could be Virginia’s maternal crossover. In fact, I think that is more likely than having four other people having their crossovers there. #2 and #3 are Pat and Joe.  #4 is a maternal 2nd cousin once removed named Sandra. More about her later. Now that I know where there is a likely maternal crossover at 25-1/2M, I’ll go back to the visual phasing.

Visual Phasing HIRs

So far with the visual phasing, everything is equal on the chromosomes. That is because, we have only dealt with FIRs and no matches. HIRs upset that balance and make us choose sides. Because the HIR creates an imbalance of one copy of the Chromosome vs. the other, we only get one shot at doing that. I don’t know if my reasoning is right, but because I have some information already for the left side of the Chromosome (Sandra), I will choose an HIR on the right side. I will choose the small HIR Lorraine and Virginia have starting at 43.5M.

Here on one copy of Lorraine’s Chromosome 22, the blue goes to brown while the other copy remains orange. Next, I see that Lorraine has no more crossovers, so I can move the DNA colors over to the right.

In addition, Lorraine and Virginia have an FIR on the right, so I can copy Lorraine’s colors onto Virginia’s maternal and paternal side. Now I have a lot of Chromosome 22 mapped out, but I still don’t know which side is maternal and which is paternal. Here is how Pat matches with Virginia, Richard and Lorraine:

Remember that Pat is a maternal cousin. It is important to note that Pat matched Virginia and Richard but not Lorraine. The yellow pattern of Pat matching Virginia and Richard matches the green above that I mapped out. That tells me that green and orange are the maternal side and brown and blue are the paternal side.  So thanks to Patricia, my in-law’s have identified maternal and paternal sides. Yay.

Next I bring back some cousin matches:

I had guessed that Virginia had to have a maternal crossover due to cousin matches at about position 24.5M. #4 above is Sandra. She is one of my in-law’s top maternal Gedmatch matches. She also is a match at AncestryDNA. She doesn’t have a public tree but she told me who their common ancestors are:

 

Sandra is a 2nd cousin once removed to Lorraine, Richard and Virginia. As such, they share only one of my in-law’s grandparents’ lines which is LeFevre.

Here is how Sandra matches Virginia and Richard:

Now I can add in LeFevre in the green segments.

Once I know green is LeFevre, then orange has to be Pouliot.

Next, I was pretty sure that Virginia had a maternal crossover at 25.5. Knowing that, I can fill in the rest of the puzzle:

  • Note that on the left had side of Chromosome 22, there are three FIRs in a row going from top to bottom. That means the three siblings have their DNA from the same two grandparents. They all have Pouliot on the maternal side and either Butler or Kerivan on the paternal side.
  • The maternal side is French Canadian.
  • The paternal side is Irish.
  • There aren’t as many paternal cousins matches to fill in the blue and brown as there are maternal matches. I’m looking for cousin matches to fill in the blanks
  • Virginia has DNA from only one paternal grandparent shown in reddish brown.
  • Lorraine has DNA from only one maternal grandparent – Emma Alphonsine Pouliot
  • There will be parts of the Chromosome where there is no DNA representation from one grandparent. For example, no one got green LeFevre DNA at the beginning of the Chromosome. No sibling got blue paternal grandparent DNA at the beginning or at the end of Chromosome 22.

 

 

More On Early Butlers In the US

In my previous Blog on the subject, I noted how two Cincinnati Butler families were connected by DNA. These were the George Butler family and the Edward Butler family. Edward Butler is an ancestor of my wife. Since then, with the help of Peter Butler, I have expanded the George Butler tree a little. Now it looks like this side by side with the Edward Butler tree.

Previously, I was hoping that Edward and George were brothers and that they would have the same fathers. However, that now does not look likely. However, it could be that George and Edward were first cousins. If that is the case, that would make Lorraine, Richard and Virginia 4th cousins to Pat and 4th cousins twice removed to Uncle Naffy.

DNA Connections Between the George and Edward Butler Families

The tree above is pared down to include only those in lines that have had their DNA tested. Uncle Naffy tested at FTDNA and uploaded his results to Gedmatch. Lorraine, Richard and Virginia are also at Gedmatch, but Uncle Naffy matches only Richard and Lorraine. Here is the Uncle Naffy’s match with Richard which is the same as his match to Lorraine.

Assuming Richard and Uncle Naffy are 4th cousins twice removed, this was a fortunate match as the chance of them matching is only a little over 10%.

By comparing Lorraine, Richard and Virginia to each other and with the help of matches with Uncle Naffy and a paternal second cousin, I was able to map out the DNA for these three siblings:

Here I presumed that the Uncle Naffy match was on the Butler DNA side of my in-law’s family. That meant that the paternal cousin’s match below had to be Kerivan as that is the only other paternal grandparent my in-law’s have. Further, the paternal cousin Gaby only matched Lorraine on the left side of the pink segment, so that meant Gaby and Lorraine had to match on their Butler side DNA.

Lorraine and Virginia match Patty

Lorraine, Virginia and Patty all tested at AncestryDNA and match each other. Lorraine and Patty are predicted 4th cousins at AncestryDNA. Unfortunately, Ancestry doesn’t show on what Chromosome the match is like Gedmatch does. Virginia and Pat also show as 4th cousins. Further Pat, Lorraine and Virginia have shared matches with those on the blue line of the tree above. All of this confirms the DNA connection between the George and Edward Butler families.

Life For the Butlers in Civil War Era Cincinnati

I would not like to have lived in Cincinnati around the time of the Civil War. For one thing, there was a war going on. For another thing Cholera outbreaks were rampant. Here was a Mrs. Butler that died of cholera in 1866:

This could have been George’s first wife Mary Whitty – except the address seems off. At this time, people didn’t understand that cholera was the result of drinking contaminated water. At this time there was a George Butler, laborer listed in the Cincinnati Directories as living at 890 East Front Street. Perhaps around here:

The 17 on this 1869 map is for Ward 17 where George Butler lived in 1860 and 1870. My research friend Peter was able to obtain a copy of George Butler’s second marriage to Margaret Sinnott.

I have the greatest sympathy for the transcriber who wrote down Surwott for Margaret’s maiden name. The marriage was on November 11, 1866 at All Saints Roman Catholic Church in the Fulton area of Cincinnati. I’m not sure where Fulton is, but there is a Fulton Avenue in the map above. Apparently Fulton was a Town in the area that got incorporated into Cincinnati around the 1840’s.

Edward Butler and Family

According to the 1860 Census, Edward also lived in Ward 17. The Cincinnati Directory of 1860 lists a laborer named Edward Butler living at the c. (corner?) of Goodloe and Leatherbury. I was interested in this location because during the same year there was a listing for George who was also a laborer b. (boards?) Reed and Leatherbury. Here is the 1869 Ward 17 map again:

Here Leatherbury is spelled Litherbury for some reason. The Street above “Continued” is East Front. The Street below “Continued” may be Goodloe. For some reason, it gives me pleasure to figure out where ancestors lived. In this case, my wife’s ancestor Edward Butler and his likely cousin George Butler.

Edward: 17th Ward to the 3rd ward

For some reason, Edward Butler and family moved to the 3rd Ward where they are listed in the 1870 Census.  When I was looking at the Ward 3 map I found the All Saint’s Church. It looks like the Church also had a school.

It is near the T and L of LYTLE’S in the bottom right of the map above. The Church appears to be in Ward 1 and Whittaker’s in Ward 3. Here is how Wards 1, 3 and 17 connect:

Edward Butlers in the Cincinnati directory

There appear to be more than one Edward Butler in Cincinnati at the time. Here are some of my listings from 1859 to 1869:

The most consistent listing is for 66 Avery, but I don’t think that is our Edward. I mentioned that I liked the 1860 listing of Goodloe and Leatherbury. Then in  1862 928 R. Front looks good. After that, in 1865, Front and Whitaker looks good. That location is on the Ward 3 Map above. That listing matches up with his Civil War service that I have elsewhere. Here are some more listings from 1870 to 1876:

I had forgotten that I had ruled out Avery in the past as I have that Edward had a son George who was believed to be born in Chicago in 1873. Here the 1870 listing of e. 3rd is a possibility. The southern half of East 3rd is in Ward 3 which is consistent with Edward Butler’s 1870 Census listing. High Street in the Ward 3 map above is also 3rd.

The takeaway story could be that Edward lived near his cousin George in Ward 17 when he first moved from St. John, Nova Scotia to Cincinnati. He moved to nearby Ward 3 to work for the Navy at the end of the Civil War. He stayed in Ward 3 until moving out of Cincinnati. This move was probably around 1870 as his son George was believed to be born in Chicago in June 1873.

Edward Butler Family 1880 Census

That leads me to the 18880 Census. I had found this Census a while ago and have gone back and forth as to whether it is my wife’s Edward Butler family or not. There is a lot right and a lot wrong with the Census record.

I’ll look at each thing that appears wrong:

  • The mother is listed as Ellen rather than Mary. However, I have her as Mary E. Crowley. Mary’s mother was Ellen which is likely her middle name.
  • Ellen is listed as widowed which I don’t believe she is. She is also listed as what appears to be wife, though possibly transcribed as ‘self’.
  • Ellen is listed as being born in Illinois. However, her parents are shown as being born in Ireland which would be correct.
  • Edward Butler is not listed. Perhaps he is traveling or working away from home?
  • I have no record of Cornelius but he may have married in the area or died. He would have been born around 1871, so this agrees with the apparent early move date to Illinois for the family.
  • Henry born in 1875 could be Edward Henry
  • I have no other record of John being born in 1879, so he may have died young or stayed in the area.

This means that I am convincing myself that this is a valid document. I notice that other related Butler researchers have used this Census as a reference in their Family Trees. This does not place the family in Chicago, but at least they are in Illinois.

Milton, Illinois

Here is a Google map of Milton:

Milton is a lot closer to St. Louis than it is to Chicago. According to Wikipedia, Milton is in Pike County.

1920 Census: A nail in the coffin for Milton

On the other hand, there is the 1920 Census. This shows that we had the wrong family in Milton in 1880:

Here we have the same Ellen, Cornelius, George and John. However, this cannot be my wife’s family as the mother Mary (Ellen?) was dead by now and George and Edward Henry were living in Massachusetts. However, that is helpful as there is no need to further pursue Milton, Illinois. We still need to find the family in 1880.

where was the edward butler family in 1880?

I have been looking for census records for quite some time. I have basically lost track of the family between 1870 and 1890. I have the Cincinnati Census of 1870. I have indirect evidence that they were in Chicago for the birth of George Butler in 1873 and Edward Butler in 1875, but no direct records of the family being in Chicago. Here  is the Cincinnati Edward Butler family in 1870.

Here is Edward Butler 20 years later in Massachusetts.

This is from FamilySearch. The top says Newton. However, the bottom of the handwritten schedule says Newtonville. The transcription on the bottom says Watertown. All these places are very close.

The search continues.

 

Two Cincinnati Butler Families

One of my Butler genealogy breakthroughs happened with a DNA match between my father in law and someone I called Uncle Naffy. I wrote a Blog on that in 2015.

Prior to that breakthrough, I had trouble tracking my wife’s immigrant ancestor Edward Butler. Uncle Naffy was from St. John, New Brunswick and told me his great great grandmother was Mary A Butler. She was living in Cincinnati and moved to St. John. There she married. Armed with that information, I was able to find the marriage record between my wife’s ancestors, Edward Butler and Mary Crowley in St. John. The record was found in scrawly handwriting on a microfilm that was in the New England Historical and Genealogical Society Library in Boston.

This St. John/Cincinnati connection confirmed the research that I had done that had located Edward Butler and family in Cincinnati in the 1860 and 1870 censuses.

Uncle Naffy’s Great Great Grandmother Mary A Butler

Recently it occurred to me that it would be a good idea to create a tree for Mary A Butler to see if we could match up the two Cincinnati Butler families (George and Edward).

This was my first attempt. As I show later, the older children of George Butler would be from a second wife. My hope was that I would find that the George Butler above was the brother of my wife’s ancestor Edward Butler. One good thing is that I have that George Butler above, married Mary Whitty. Whitty is a less common name than Butler. A search for George Butler at Ancestry turned up this as a clue:

Here is a George Butler and Mary Whitty that gave birth to an Anne Butler on March 31st 1850 in the Parish of Ferns, Wexford. The good news is that the George Butler Family in 1860 in Cincinnati also had a daughter named Ann born about 1850 in Ireland. This is a good match.

A little more searching revealed a marriage between George “Butta” and Mary Whitty:

The transcriber saw Butta, but I can also see Butler there. I doubt that Butta is a very common name! As in the birth of Anne above, there is a Whitty and Hendricks as witness. The additional information is that they lived in Mountain Gate. I was curious as to where Mountain Gate is and was able to find a Mountaingate:

I have panned the map out a bit to show the relationship between Mountaingate and Mooncoin. They appear to be about 25 miles from each other. In one of my previous Blogs, I pointed out the my wife’s ancestor Edward Butler is listed as being from Wexford on one of his son’s death certificate.

Another Wife for George Butler?

There is also a tree at Ancestry that has Margaret Sinnett as George Butler’s wife. It appears to me that Mary Whitty died sometime between 1860 and 1870 and that George remarried.

Here is it clear that Mary must be from the first marriage as she was born before 1860 when Mary Whitty was still around. I could guess that Henry would be the son of Mary Whitty as there are 7-1/2 years between him and Rebecca. However, I cannot be sure just from the Censuses. So my basic take is like this:

I’m missing some children from George’s second marriage to Margaret Sinnett. I was having a hard time making this family come out right on the Ancestry Tree.

One last point about Margaret is that Pat has her mother Catherine as being from Killaspy, County Kilkenny. Here is a map showing an arrow where Killaspy is:

This was interesting to me because with the help of a Butler researcher in England, my wife’s Butler family has been located near Mooncoin on the top left of the map above. Mooncoin appears to be about 5 miles away from Killaspy.

Another Cincinnati Butler DNA Match

The previous image brings up another interesting point. My wife’s two Aunts have had their DNA tested at Ancestry. They both match Pat who descends from Rebecca Butler b. 1869 above. My father in law matches Uncle Naffy at Gedmatch. That makes a good case that George Butler is related to Edward Butler, my wife’s ancestor who also lived in Cincinnati.

Here is Rebecca Butler’s Certificate of Death showing her two parents.

This could be a case where the death record is not the best source of a birth date as Rebecca was shown as being 6 months old in the 1870 Census and born in October. So the day and month only are probably right in the death certificate.

Here is how my wife’s Aunt Lorraine matches Pat:

Pat matches my wife’s Aunt Virginia a little less: 29.9 cM across two segments.

Another Shared DNA Match At Ancestry

Pat and my wife’s two Aunts also have two shared DNA matches. These matches have this tree:

I’m not sure if it was Donna that took the AncestryDNA test. It appears that more than one in the family did. At any rate, the match is much higher. It is now at 183 cM across 9 segments. The average amount of DNA shared between a 2nd cousin once removed is 129 cM.

In comparison, here is Lorraine and Virginia’s tree next to the previous tree:

In the above scenario, Lorraine, Richard and Virginia would be 2nd cousins once removed to Donna and family. I’m not sure if Cornelias and John in Donna’s tree are right. Also, Donna’s tree has Henry, where I have Edward Henry. They are apparently the same person.

So Where Does That Leave the Butlers?

Here is a partially combined tree:

I say partially combined, because I haven’t connected the orange with the green side by genealogical research. I slimmed the tree down to just include the direct lines of those who have had their DNA tested. Uncle Naffy matches Richard at Gedmatch. Pat and Donna’s lines have not uploaded their results to Gedmatch. Pat and Donna’s line have shared DNA matches at AncestryDNA where they tested. Pat also matches Lorraine and Virginia at AncestryDNA. In addition, Donna matches Lorraine and Virginia. Richard and Uncle Naffy have tested at FTDNA, so unless Donna’s line and Pat upload to Gedmatch, those matches won’t be made known.

Summary and Conclusions

  • The George and Edward Butler families are linked by new and old world locations and DNA
  • More work is needed to link the George and Edward Butler families by paper research.

 

Chasing Down More Rooney Connections

In my previous Blog on the Rooneys, I looked at how my wife’s Rooney ancestors may be connected to another Rooney line by DNA and genealogy. I came up with a proposed genealogy/dna chart that looked like this:

Triangulation With the Rooney DNA Match

Triangulation is when three or more people all match each other on an overlapping segment of the Chromosome. This happens on Chromosome 14. Here are the Rooney DNA match’s matches with my father in law Richard (1), his sister Lorraine (2) and Gaby (3):

A Triangulation Group (TG) indicates a common ancestor. In this case, I believe the common ancestor to be Timothy Rooney:

Jenny’s Rooney Connection

There is another Rooney connection. Jenny doesn’t match my wife’s family as strongly as the Rooney match in purple above does.

It looks like Jenny has also tested her brother. The above chart shows that Jenny is a second cousin to the Rooney match discussed in my previous Blog.

Virginia and Richard match Jenny on Chromosome 11 from about 118 to 124M on the Chromosome Browser:

The DNA I have mapped for Virginia and Richard corresponds to their Kerivan grandparent:

This Kerivan mapped grandparent is the same one shown in green on the genealogy/dna chart above. It represents Lilly Kerivan, daughter of Alice Rooney.

Just so we don’t leave out Jenny’s brother, here are some of his matches with my wife’s family on Chromosome 3:

These matches are with Richard, Virginia and John. In my opinion, each match between my wife’s side and Jenny would represent DNA from Timothy Rooney born about 1807.

Here is Richard and Virginia’s Chromosome 3 mapped out.

The Rooney match would be in a Kerivan segment. That means that the dark red segment is probably Kerivan. The blue and purple above are on my father in law’s mother’s French Canadian side.

More Rooney Genealogy: Are Timothy and Terrence the Same?

Jenny and and her 2nd cousin Daniel have in their trees as their first Rooney ancestor Terrence Rooney. That is not surprising considering the marriage record of their great great grandfather, John Rooney:

Above are the listed parents for John Rooney and his wife. The date of the record is May 19, 1851. The record is for the Intentions of Marriage, so this would have been soon before the couple was married. Here is a marriage record for a John A and Mary Rooney:

The date of marriage was listed as May 9, 1851. Here quite a few things seem off. The wife is now Mary Rooney rather than McDermott and both parents are Patrick. They are listed as being in Boston rather than Dorchester although both places are very close. Note that John is a mason here. After a bit of digging, it appears that there were two John Rooneys of about the same age that married two Mary’s of about the same age. Isn’t that confusing!

A proposed sketch of Timothy Rooney

My thought is that Timothy Rooney, son of John Rooney and Ann was born in County Leitrim around 1807. He married Margaret Ann Gorman around 1828. Around 1830, he had a son that he named after his father John. Timothy’s first wife likely died and he then married Ann Nancy Lilly probably around 1832. She had about 10 children between 1834 and 1851.  John took off for Boston not too long before he married in 1851. Timothy landed in Boston in 1858 with his wife and some of his children in June 1858:

The 1860 Census shows Tim and family in Waltham:

Timothy died in Newton at the age of 74 in 1881. His occupation was listed as mason.

Summary and Conclusion

  • The DNA leads me to think that Terence and Timothy Rooney are the same person.
  • If they were the same person, the timing would seem to fit in. He would have had time to have two wives giving birth to the children that we know of.
  • The fact that Jenny, John and Gaby have matches seem to reinforce that the DNA that these two families share focus in on Timothy or Terrence Rooney.
  • I can’t prove that Terrence and Timothy Rooney by either the genealogy or the DNA. However, the DNA does point to a common ancestor. Why couldn’t that ancestor be Timothy or Terrence?

 

Chasing Down My Wife’s Rooney Connections

My wife’s father is half Irish and half French Canadian. On the French Canadian side there seems to be  a lot of genealogy and a lot of DNA matches. On the Irish side, there is a not so much genealogy and a lot less identified DNA matches.

Mapping the French Canadian and Irish In Laws

I have used a method to map out my father in law’s DNA that he got from his four grandparents. To do this, I compared him to his two sisters, Lorraine and Virginia. Here is their Chromosome 14.

The good news was that I could map the Chromosomes by looking at the DNA results of the three siblings compared to each other. Then I could find many matches to reference the French Canadian side. That got me the LeFevre and Pouliot grandparents above. The problem was that I couldn’t find enough matches to reference the Irish side.

Gaby to the rescue

However, on AncestryDNA I found my wife’s 2nd cousin on the Irish side. Because of Gaby, I can now tell which of my father in law’s grandparents are Irish.

Any DNA matches that Gaby has in common with Lorraine, Richard or Virginia are Irish. Gaby and my wife Marie, share the same Butler and Kerivan Irish ancestors. The next problem is that we can’t tell whether these matches are Kerivan or Butler.

Working Gedmatch To Get Kerivan and/or Butler Matches

In order to separate the Butlers from the Kerivans, we need to find matches that are further out. To find these I looked at DNA matches at Gedmatch that matched both Gaby and Lorraine. I used Lorraine because she was tested at AncestryDNA. The matches would be on the Irish side. That was the first cut. Next, I hoped that some of these matches would have trees at Ancestry that would match my in-law’s tree.

For example, here is someone that matched both Lorraine and Gaby on our example Chromosome 14.

The above image shows how Lorraine matches someone with a Rooney name (#1) and Gaby (#2). This tells me that this Rooney match is on the paternal side or Irish side, so that is also good. The other good thing is that my father in law’s grandmother’s mother was a Rooney:

All I have to show is that the match indicated in yellow above with the Rooney name is related to Alice Mary Rooney above. There were other common surnames, so the match didn’t have to be a Rooney. However, I noticed that there were some Rooneys in Massachusetts which is where my wife’s Rooney ancestors lived. Based on that, I thought that it would be a good idea to start with Rooney.

Doing the Rooney Genealogy

Lorraine’s Rooney AncestryDNA match that is also at Gedmatch and matches with Gaby at Chromosome has a Rooney Tree:

However, these two trees seem a little out of whack. Maybe Timothy Rooney in my wife’s tree could be a brother of Terrance Rooney in the Rooney tree?

A third Rooney Tree

I found another Rooney tree as an Ancestry Hint. It looks like this in a different view:

This tree shows that Timothy Rooney had two wives. It appears that Margaret Gorman was the first wife and had a John Rooney born 1827. Apparently Ann Nancy Lilley was the second wife and had Alice Mary Rooney. That could explain why the two trees didn’t match up. This tree shows the Terrence Rooney from the Rooney Tree as the same Timothy Rooney from my tree.

Putting the rooney trees together

Assuming that the Rooney Tree reconciliation was correct, the Rooney DNA match on the bottom right in purple would be a 1/2 third cousin once removed to my father in law Richard and his two sisters.

Back to the Chromosome 14 Map

That looks better. We now have the paternal side thanks to Gaby and a Rooney match. When I check the Rooney match, he matches Lorraine and Richard, but not Virginia.

The yellow matches on the Gedmatch Chromosome browser correspond with the green in the Chromosome 14 map above. The crossover for Richard at 54M also shows up.

The other good thing about the new Chromosome map is that it shows where the Butler matches would be. This is like a spy glass looking into the past. A match on the Butler side is like a match with Virginia’s grandfather who was born in 1875. Matches to these grandparents should be helpful in straightening out my wife’s Irish genealogy.

Summary

  • Use a paternal cousin to find other paternal cousin matches that are more distant
  • Connect that further out cousin to a known ancestor
  • Use that further out cousin match to complete a Chromosome map
  • Use that completed Chromosome map to identify other cousins as they match in identified areas of the Chromosome map representing grandparents of my father in law.
  • Use those identified matches to focus on further genealogy and break down former research barriers.
  • This method works best with people that have DNA testing results at both Gedmatch and Ancestry.

Gaby’s Butler and Kerivan DNA

My wife’s cousin Gaby recently uploaded her AncestryDNA results to gedmatch. That is good news for my Butler and Kerivan research. My wife’s father is a Butler and a Kerivan on his father’s side. However, because he is also half French Canadian on his mother’s side, he gets a lot of French Canadian matches. Those matches make if difficult to find the Irish Butler and Kerivan DNA matches.

Gaby’s Overall DNA Matches at Gedmatch

Here are Gaby’s top DNA matches at Gedmatch:

  • Already, there are a few interesting things. One is that Gaby has some X Chromosome matches with Virginia and Lorraine. Virginia and Lorraine are my wife’s aunts. We will look at that later.
  • The next point is that Gaby shares about the same amount of DNA with my wife Marie as she does with Marie’s Aunt Lorraine. Such is the randomness of DNA inheritance. Gen in the Chart above means generations to a common ancestor. For example, first cousins have 2 generations to their common or shared grandparents. Marie’s ‘Gen’ amount should be 3.0 (on average) to Gaby as those two are second cousins. Aunt Lorraine should be 2.5 from Gaby as they are 1st cousins once removed.

Butler/Kerivan Genealogy

Here is a brief genealogy as it relates to those close relatives DNA tested and uploaded to Gematch:

Those that have DNA tested and are listed at Gedmatch are in dark bold. Marie, John and Gaby are each 2nd cousins to each other. The 5 testers on the left will share French Canadian LeFevre DNA with each other. However, now with Gaby, the left hand side above will share only Butler and Kerivan DNA. Likewise from Gaby’s point of view, her matches take her Melsis ancestors out of the matching.

Kerivan X Chromosome Matches

I mentioned above that Gaby matches Lorraine and Virginia by X Chromosome. My guess is those matches are Kerivan and not Butler matches. Why do I think that? The important thing to note about the X Chromosome is that the son inherits no X Chromosome from the father. However, Lorraine and Virginia inherited an X Chromosome from their father, Edward Butler b. 1904. That Edward inherited no X from his dad, but did inherit X from his mother Lillie Frances Kerivan, born 1874.

Here is Lily Kerivan’s X DNA that is shared between Gaby, Lorraine, and Virginia:

gaby’s additional X Chromosome DNA

But there is more. Gaby gets more X Chromosome DNA than those on the left side of the Butler/Kerivan genealogy chart. Gaby gets some Crowley X Chromosome DNA.

Following up the tree from Gaby, she got X DNA from her mom, who got it from her mom Lily Butler. Lily got her X DNA from her mom and dad Edward Henry Butler. Edward got all of his X Chromosome from his mom Mary Crowley, b. 1838 in St Johns, New Brunswick. So Gaby may have some of  this old X Chromosome DNA. I say she may as we don’t know for sure. Perhaps it dropped out along the way. However, the potential is there.

Finding other Butlers and kerivans

One way to find other matches on the  Butler and Kerivan sides is to run a utility at Gedmatch. The utility is called ‘People who match one or both of 2 kits’. We are interested in those who match both my father in law Richard and Gaby.

If I choose Richard’s kit number first, I’ll get those in common with Gaby that match Richard. If I choose Gaby’s kit number first, I’ll get her matches that are in common with Richard. I’ll choose Richard’s kit number first as I already have a spreadsheet of a lot of his matches. Here are the results:

I left out the kit numbers on the left and the emails on the right. Also on the right is a check box to choose all the matches where they can be compared. The first three columns are for Richard and the second three are for Gaby. When I pick a lot of the check boxes, I can then compare them in a Chromosome browser.

This is an example of one of the Chromosome’s results. #1 on the browser is a Rooney. There are Rooney’s on the Kerivan side, so this is a good sign. #2 is Gaby. It looks like she is related to #3 also. Now I can go to Richard’s match spreadsheet. I can make an educated guess that both these matches are on his Paternal side.

The first entry in blue above is the Rooney person. The second in blue is Gaby. Others in blue are likely related along that Kerivan or likely Rooney line. The blue means a paternal match. Notice that there are a few other matches with known relatives above that are maternal matches in the same area of the Chromosome. I have them in pink for maternal. Knowing if your matches are paternal or maternal is one of the most important things to know about autosomal DNA matching. If you get that wrong, you will be chasing DNA down the wrong road.

Double Visual Phasing

Many articles have been written lately about visual phasing. This is a method developed by Kathy Johnston. I would like to write about double visual phasing. Previously, I had tested my father in law and his two sisters and tried visually phasing them. Here is the result of my attempt to visually phase their Chromosome 15:

Chromosome 15 – Richard and Sisters

I can tell that I did this a while ago as it was done in MS Word which I don’t use now for visual phasing. L is Lorraine, R is Richard and V is Virginia.

What is Double Visual Phasing?

This is a term I made up. I’m guessing that others have tried this, but I have not seen any Blogs on the subject. Richard has a second cousin named Fred. He is related on the Pouliot side (in orange above). Fred has had his sister Sleuth tested and his brother Don. If I phase Fred and his two siblings who are related to Richard and his two siblings, I’ll have double phasing. As they both share a Pouliot grandparent, it will be interesting to compare the results.

A Brief Genealogy

For the purposes of this Double Visual Phasing, here are the people involved:

Let’s Visually Phase Fred and His Two Siblings on Chromosome 15

The first step is to compare the three siblings to each other at Gedmatch.com using the Chromosome Browser:

I used MS Excel for this and I adjust the columns to the segment changes. Note that all the segments don’t line up perfectly, but I’ll say they are close enough. Next I add locations in millions:

I also put in darker vertical markers. I’m hoping that the places where the segments don’t align perfectly do not indicate additional crossovers.

Next I need to show who the crossovers belong to:

From this, it looks like Fred has four crossovers, Sleuth has two and Don has only one. Fred’s first crossover is at position 22M.

Next, I can assign colors based on Fully Identical Regions (FIRs). In these regions, there will be a match on both one maternal and one paternal grandparent. These grandparents will be represented by two of the same colors in that region extending to the person’s next crossover.

Where there is no match, I can assign two different colors and extend those to each persons’ crossover.

I make sure that the boundaries for each person line up with their crossovers. So on Fred’s map his first FIR with Don is short as it is within Fred’s two crossovers.

Mapping Half Identical Regions (HIRs)

Here I get one chance to map an HIR. My inclination is to map the HIR on the right between Sleuth and Don. My reasoning is that Sleuth is already at her last crossover at that point, so I’ll extend her segments all the way to the right. I already know from my previous map for my father in law’s family that Fred has some matches with my father in law and his two sisters on the left side of Chromosome 15 shown in Orange. So that information may help me map the left side of Chromosome 15:

Chromosome 15 – Richard and Sisters

Here is Fred and family’s partially completed Chromosome 15 with the HIR added for Sleuth:

However, there are blanks. Also we haven’t figured out which side is maternal and which side is paternal.

Two other testers

There are also two other testers: Patricia and Joe. They are my father in law’s first cousins. They are related like this:

The next thing I do is to compare all these eight people in gedmatch.com to each other. I download the results into a spreadsheet. Here are the matches on Chromosome 15:

I have the matches between siblings filtered out so they don’t show. I have Fred, Don, and Sleuth in the first column and the others in the second column. Every match represents DNA from Joseph Pouliot (or his wife Josephine Fortin – let’s not forget her). The way I have it mapped right now, the most important match is Joseph to Don and Sleuth. The only place that match could be is on the blue portion:

This is good news, because this sets the paternal and maternal sides for Fred, Sleuth and Don. It also sets where their paternal grandparents are. Here are Fred’s grandparents:

That means that blue is Pouliot and pink is Ford. Like my father in law’s family, Fred has a French Canadian side and an Irish side.

Next, we should be able to fill in the left side of the puzzle using the other matches:

A few observations:

  • The same match that Fred had with my father in law’s family helped finish my father in law’s visual phasing and Fred’s visual phasing.
  • All four of Fred’s grandparents DNA is represented between the three siblings. The one exception is a small portion of green from 22 – 27 M on the maternal side
  • The purple segment that Fred has from 22 – 27 seems quite small. It is a little unusual to have a small internal segment like that. By internal, I mean a segment that is not right on either end of the chromosome
  • Without the match between Joe, Sleuth and Don, I don’t know if I would have been able to complete this Chromosome
  • I don’t know about Fred’s maternal [Irish] side. He may already have matches that would identify the Halloran and Drennan DNA.

Comparison of the Double Visual Phasing

  • Unlike Fred’s results, my father in law’s family does not have good Pouliot coverage (in orange) between the three siblings.
  • This explains why Richard’s family matches Fred’s family in the beginning of the Chromosome and not the end. Pouliot DNA is missing between 60 and 95M.
  • It appears that Sleuth and Richard could have matched between 95 and 100, but I didn’t find a match over 3cM. Could this be because one received DNA from Joseph Pouliot and one received DNA from his wife, Josephine Fortin? Perhaps this is also an explanation of why the match between Don and Viginia (V) stops at position 38M.

Summary

  • Double visual phasing has benefits in that there are at least six people to compare matching DNA results with each other.
  • Double visual phasing should result in a crosscheck for the visual phasing of each family and better Chromosome maps of contributing grandparent DNA.
  • There are benefits in noting which group has the better coverage of DNA of a shared ancestor.
  • Comparison of results appear to indicate deeper crossovers between ancestors

Next Up

There are matches between Fred and his two siblings and the other five tested people on every chromosome except for 18, 19 and 22. That should make mapping the chromosomes with matches relatively easy.

I would like to try double visual phasing between two sets of siblings where the siblings are from different generations. However, it may take a while to get the additional samples done.

Determining Whether a Match Is Irish Or French Canadian By Visual Phasing

In this Blog I will look at a DNA match that my in-laws have. I would like to know whether the match is Irish or French Canadian. I will use Visual Phasing of my father in law and his two sisters’ DNA match to try to figure that out.

Irish at First Look

Something caught my attention with one of my father in law’s matches at FTDNA. My father in law Richard’s match Ann had this tantalizing detail under her Ancestral Surnames:

White (County Waterford Ireland to New Brunswick Canada)

I had recently found out, with the help of DNA and DNA researchers, that my father in law’s immigrant ancestor had shipped out from Waterford to New Brunswick. I have very few DNA matches for my father in law on this Irish side that I have identified. Most of the matches are French Canadian.

Irish or French Canadian?

At first, I didn’t notice other French Canadian names in Ann’s ancestry. However, after finding out she was listed at Gedmatch and Ancestry, I looked at her Tree and did see some French Canadians.

Visual Phasing

I do have DNA from my father in law Richard and his two sisters Lorraine and Virginia. So perhaps Visual Phasing will give and answer to the question whether the match with Ann is French Canadian or Irish. Ann’s best match to Richard, Lorraine and Virginia is on Chromosome 9:

Lorraine has the largest match above followed by Richard and Virginia. It looks like Richard and Virginia have crossovers at about position 107M.

I have used MS Word for phasing, but it wasn’t the best. PowerPoint worked well, but lately I have preferred using Excel. First I cut and paste the comparison of the my 3 in-laws into Excel.

Then I add the crossover points for the three siblings:

At first I thought that the first crossover belonged to Richard. however, there is a short break in the Lorraine V. Virginia comparison, so that adds an additional first crossover for Virginia. Actually the Virginia/Richard should be Virginia/Lorraine. There are likely 2 close crossovers there. I ignored the last small match between Lorraine and Virginia as there wasn’t anything going on in the comparisons above and below that match. Next I add the locations of the crossovers:

Lorraine and Richard have the largest Fully Identical Region (FIR) shown in green. I map that with the same two colors for Lorraine and Richard:

Lorraine only has two crossovers, so we extend her colors all the way to her left crossover and on the right to her crossover (L):

As Lorraine only had two crossovers, this perhaps explains why she had the largest match with Ann on Chromosome 9. Next, I fill in FIRs and Regions that don’t match (shown as red in the Gedmatch comparisons) with corresponding colors:

Unfortunately, that lead to a bit of a dead end. Instead, I’ll try starting with the Richard and Virginia FIR on the bottom comparison:

This version looks better. Next we choose a Half Identical Region (HIR) shown as yellow above. The longest one starts at position 14 between Lorraine and Virginia. A HIR maps as matching only one color and not matching the other.

Above, I chose for Lorraine and Virginia to match on the green and not match on purple and yellow. That is how the HIR is represented. I can then extend Lorraine’s purple and green to her crossover (L) on the right and fill in more FIRs and non-matching areas:

Now, except for the two ends of Virginia and Richard, I have a four grandparent map represented by four colors. Next, we have to identify the grandparents.

The Pouliot French Canadian Connection

One of my in-laws’ grandparents is a French Canadian Pouliot. Fortunately, my in-laws have a Pouliot cousin named Fred. Fred’s sister has also tested. Here is Fred’s matches with Virginia (78-83.5 and 107-110) and Richard (107-115).

Here is Fred’s sister’s matches with Virginia, Richard, and Lorraine.

Note that Lorraine only has one small match with Fred’s Pouliot sister. This is leading me to believe that the match with Ann is on the Irish side. Can we use these Pouliot matches to identify our blank map above? I think we can. The 2 green matches above are for Virginia and Richard at 17-31M. The only place between 17 and 31 where Fred’s sister could match Virginia and Richard, but not Lorraine is on the yellow. If the match were on the green segments, Fred’s sister would have had to have matched all three siblings at that location. Note that mapping out the smaller matches should also be on the yellow segments.

I should point out that my in-law’s had a father of Irish descent and mother of French Canadian descent. This means that both their paternal grandparents were Irish and both their maternal grandparents were French Canadian. As Pouliot is the maternal grandfather, that sets the maternal side of the map as yellow and purple. That also sets purple as the other maternal grandparent: LeFevre. Further, salmon and green now represent the paternal Irish grandparents.

So Is Ann a French Canadian or Irish Match?

Although I was leaning toward the Irish earlier, I now think that the match is French Canadian. Take another look at the match between Ann and Lorraine, Richard and Virginia:

The pattern looks a lot like the purple LeFevre segments. Lorraine’s larger match is on top. Richard’s green match stops where the purple LeFevre segment stops. Virginia’s smaller blue match starts where the purple Lefevre segment starts again. I’ll put the matches in the same order as Gedmatch to make it easier to see:

If Ann were to have matched on the green paternal grandparent area, there would have have to have been three equal matches in that region shown on the Gedmatch browser.

The fact that Ann did not match with the French Canadian Pouliot grandparent did not mean that she was an Irish match. In this case, it meant that she matched the other French Canadian Grandparent.

Summary and Conclusions

  • Visual Phasing can help map an unknown match to a grandparent.
  • That phasing needs to be in conjunction with at least one known cousin to identify a grandparent.
  • These results help to know where to invest genealogical research time. There is no sense in barking up the wrong tree.

Using Three DNA Tools Synergistically

In this post, I would like to look at using three DNA tools in conjunction with each other. Those tools are AncestryDNA’s Shared Ancestor Hints (SAH’s), Visual DNA Mapping, and Triangulation. This will be a triangulation of DNA tools, so to speak.

The above diagram is meant to show Shared Ancestry Hints at the top. The lower left is the visual mapping and the lower right is a symbol for triangulation. In my last blog, I looked at an SAH and visual mapping example. This blog will bring in another tool: triangulation.

Shared Ancestry Hints (SAH’s)

SAH’s are probably the least reliable of the three DNA analysis tools, but they are like the front man or salesman. They are the first easy introduction to a possible shared ancestor based on a DNA match. They are also the least intelligent. Ancestry takes a tree and takes a DNA match and blindly puts them together. Here is my wife’s aunt Lorraine’s  SAH that I looked at in my previous Blog:

Fortunately, Ann uploaded her DNA to Gedmatch. Here is how the match looks between Ann and Lorraine:

This is a huge amount of DNA shared for the proposed 8th cousin relationship. This Charles Pouliot at the SAH was born in 1631.

Visual Mapping

This method, developed by Kathy Johnston, compares three siblings and draws a map showing the DNA that the three siblings received from their four grandparents. Here is the map I made in my previous Blog for my wife’s Aunt Lorraine and her two siblings:

After looking at the map for Lorraine and comparing it to the SAH, I determined that the Chromosome 4 DNA match between Ann and Lorraine could not be on the Pouliot side as hinted at by the SAH. Lorraine’s match with Ann was squarely in the largest maroon LeFevre segment between 33 and 40 above. As the goal of the previous Blog was to compare the SAH with visual mapping I did no further analysis. I could not prove that the match indicated LeFevre or LeFevre ancestor DNA. I also could not prove that it did not represent LeFevre or LeFevre ancestor DNA.

As the above analysis was limited by the goal of that Blog, I wanted to look further into the DNA match between Lorraine and Ann in this Blog.

Triangulation

Triangulation is the matching of three or more people with each other on the same segment of the same chromosome. This specific DNA matching suggests a common ancestor that sent his or her DNA down to the three or more matching people. Further the matching would in most cases rule out spurious, false or Identical by Chance (IBC) matches.

candidates for triangulation

The people that I am looking to triangulate are:

  • Ann and Lorraine
  • Lorraine’s siblings Richard and Virginia
  • Lorraine’s Pouliot second cousins. A Pouliot DNA match on Chromosome 4 has been ruled out by Visual Mapping, but there could be a match on the other 3 Chromosome matches.
  • Lorraine’s 1st maternal cousins. These two match on the LeFevre and Pouliot sides.

Of the three siblings, only Lorraine matched Ann on Chromosome 4. Ann did not match the two Pouliot 2nd cousins at standard Gedmatch thresholds. Ann also did not match one of Lorraine’s first cousins, but matched the other one – Joseph:

Here is a graphic of the testers. I forgot to mention John above. He also did not match Ann.

This graphic shows Pouliot at the top, but the mapping showed that the Chromosome 4 match came from the LeFevre side. Here is Martin LeFevre courtesy of cousin Patricia:

back to the triangulation

Lorraine matches Ann and Ann matches Lorraine’s 1st cousin Joseph between 32 and 40 on Chromosome 4. Do you think that Lorraine matches her first cousin at this location? The answer can be seen at Joseph’s matches on the Gedmatch Chromosome Browser:

These are Joseph’s matches to:

  1. Lorraine
  2. Virginia
  3. Richard

Joseph and Lorraine have a large match between 13 and 65M. That means that Triangulation has been established between SAH Ann, Lorraine and Joseph.

What Have I Shown?

I have shown that:

  • The match between Ann and Lorraine on Chromosome 4 is real.
  • That match indicates that Ann, Lorraine and Joseph have a common ancestor

What I don’t know:

  • Right now I have not determined the common ancestor indicated by the Triangulation. AncestryDNA indicates a choice of 15 ancestors shared between Ann and Lorraine. One of those, the Pouliot ancestor shown on the SAH has been ruled out. That leaves 14 other French Canadian names to look at!
  • I don’t know which segments were considered in the AncestryDNA match as Ancestry does not choose to share that information. Gedmatch showed matches in 4 segments on 4 chromosomes. AncestryDNA only showed two matching segments.
Looking at Lorraine and Ann’s genealogy: Shared Ancestral Names and Shared Matches

Here are the shared ancestral names between Lorraine and Ann:

Further, Ann and Lorraine have shared AncestryDNA matches. Here are the shared ancestral names with one of those shared DNA matches that has a tree:

A good place to start looking would be at Bergeron, Bouchard, Fortin, Girard, and Paradis.

Here is another Shared Match with a smaller tree:

This seems to limit the look to Bouchard, Fortin and Girard. Just to make life interesting, all these names are also in the better documented Pouliot tree. Yes, that is the same Pouliot where the DNA between our matches did not come from.

Here is the Tree I have for LeFevre:

See, I have a few blanks. On this tree, it appears that Bergeron (shown twice) could be a good bet to pursue. Perhaps Lorraine got Bergeron DNA from Martin LeFevre’s paternal and maternal sides. Under that scenario, she could have shared one of those 4 segments with both Ann and Joseph on Chromosome 4.

some late breaking news

Since starting this Blog, I decided I needed to spruce up the French Canadian side of my wife’s Ancestry Tree. I’ve worked on that a little and see there is at least one Bergeron common ancestor between Ann and Lorraine on the LeFevre side:

The SAH Anne’s ancestry is on the left and my wife’s LeFevre’s ancestry is on the right. I checked some other possible common names and found no obvious matches. Perhaps the above Jean-Baptiste Bergeron is the one who sent down his DNA to three of his descendants.

Here is what the shared genealogy looks like on a chart:

I would expect a new Shared Ancestor Hint at AncestryDNA based on the updated genealogy I filled in.

Summary and Conclusions

  • The Shared Ancestor Hint was like the salesman that got his foot in the door. His sales pitch, however, was based on shaky information. That shaky information is the ancestor trees as many others have pointed out. There is also an inclination by some to extend the trees of the names that they are more familiar with rather than extending all the family names back in time. For example, my wife’s grandmother was a LeFevre. When I was researching, I didn’t take the time to follow every line back to France via Quebec. Instead, I researched the familiar LeFevre line.
  • The visual mapping showed that the Shared Ancestor Hint could not indicate a match between the DNA and the common ancestor shown (Pouliot). This was a tearing down phase that showed something to be wrong, but did not show what was right
  • The triangulation was a re-building. It showed that the Chromosome 4 match was indeed valid and pointed to a common ancestor.
  • As a result of the Chromosome 4 triangulation, it showed that it would be worthwhile to further pursue who the common ancestor may be between Ann, Lorraine and Joseph. My initial shot at that indicated a possible Bergeron common ancestor.

 

 

 

A Shared Ancestry Hint of a French Canadian 8th Cousin and Visual Mapping

Recently I have been looking at my wife’s French Canadian Pouliot ancestry and DNA. My thought has been to find a Shared Ancestor Hint (SAH) at AncestryDNA. Then if the person in the Ancestry hint has uploaded their results to Gedmatch, I would be able to analyze those results. In this case, I would like to check using visual phasing to determine whether the match is on the Pouliot line or another line.

Here is the SAH:

Lorraine is my wife’s paternal Aunt. Here is what the DNA looks like at AncestryDNA:

Here is how the match looks like at At Gedmatch,

Actually, based on this person’s email, there are 2 matches. This is the Ancestry one. The other test was at 23andme. They are likely the same person. This AncestryDNA match got higher results perhaps due to the comparison within the same company.

The Goal: Compare Gedmatch, AncestryDNA and Visual Mapping

My goal as stated above is to map one or more of the matching Chromosomes to see if the match along the Pouliot line is likely. I do have two Pouliot 2nd cousins to Aunt Lorraine which will help. It would make sense to map the Chromosomes where they match Aunt Lorraine. Here is how Fred, who is a Pouliot 2nd cousin to Lorraine matches Lorraine on Chromosomes 4:

  1. Richard, my father in law
  2. Richard’s sister Lorraine
  3. Richard’s sister Virginia

Now To Visually Map Richard, Lorraine and Virginia On Chromosome 4

The good news is that there is a lot of Pouliot DNA for mapping this Chromosome. The bad news is that the original Chromosome match between Ann and Lorraine was fairly small.

First I compare the 3 siblings using the Gedmatch Chromosome Browser:

In the image above, I’ve added the crossovers and the approximate locations on the Chromosome where they occur. There are a lot of crossovers bunched up on the right side. Next I assign the crossovers to a particular sibling. Note that I added two crossovers that I missed in the previous image:

  • Virginia has 109 crossovers
  • Richard has 3
  • Lorraine has 4 for a total of 17 crossovers. I have a question mark my Lorraine’s last crossover as I’m not sure if there is one there or not.

Next I map the 3 siblings based on crossover, Fully Identical Regions (FIRs in green), Half Identical Regions (HIRs in yellow) and the places where the siblings don’t match in red.

I’ll start in the middle of the Chromosome where Lorraine and Virginia have a FIR going over two segments (before positions 120):

This gets us started. The DNA that these 3 siblings inherited from two of their same grandparents are represented by green and purple and extend to each of their crossover lines. Next, I look for other FIRs or places where the siblings don’t match. For example, Richard and Virginia don’t match between 59 and 84, so I’ll add two new colors to Virginia, to show the DNA she got from the other two grandparents.

Here it looks like I’m stuck for now:

Now I add a HIR. Our Gedmatch match between Lorraine and Ann was between 33 and 40, so I’ll add one for Lorraine there.

I did this by arbitrarily extending one of Lorraine’s colors to the left and choosing another color to add so Lorraine and Richard would be HIR between 31 and 84. Then I extended those colors to the left as Lorraine had no crossovers on the left side of the Chromosome. Based on this HIR, I can fill in some more on the left had side:

Now I have a lot of the left side of Chromosome 4 mapped out. I also have Fred who is a second cousin on the Pouliot side. I’ll mush all the information together and then try to figure out what color Pouliot is:

Here I’m leaning toward a purple Pouliot. The reason is that Richard has a purple segment (and Pouliot match) from 4 to 14. Richard, Lorraine and Virginia match Fred from 102-126, but Richard may not be mapped in that area yet. However, Lorraine and Virginia have purple in that segment. In addition, I don’t have positions for the two crossovers between 95 and 120. I can get those from Gedmatch by comparing Richard and Virginia’s FIR at full resolution:

The FIR starts a little after 100M and ends at about 106.5. Those two positions numbers define the two crossovers between 95 and 120. That also confirms that Pouliot is purple. This defines a grandparent and the maternal and paternal sides of the Chromosome as Pouliot is on the maternal side for these three siblings. It also defines the other maternal grandparent (LeFevre) as being the red or maroon color.

Next, I can fill in all the other Pouliot sections provided by these 3 siblings’ Pouliot cousin Fred:

A few notes on the mapping:

  • Virginia didn’t match Pouliot from 4-14 where Richard did so she gets a LeFevre segment there.
  • Virginia also does not match Pouliot from 120 to 135 where her siblings do match Pouliot. So I give her another LeFevre segment there.
  • Virginia starts matching Pouliot again at 172. This points out a crossover location that I mislabeled previously as 177. Corrected above.
  • There is still a few small segments on the right that I haven’t filled in for Virginia and Richard.
Some additional adjustments

A close look shows that between 180 and 185, Lorraine and Richard don’t match. In order to meet the FIRs, HIRs, and no-matches on the right hand side, I came up with this:

I’m not sure if this is totally right on the right hand side, but it seems close. I show Virginia as having nine maternal segments which seems quite unusual. I would like to point out that the match on Chromomse 4 between Lorraine and Ann. Ann did not match Virginia or Richard on Chromosome 4. Those results (and lack of results) are consistent with the mapping above.

Back to the Original Match Between Lorraine and Ann

A big part of this Blog was to determine whether Lorraine’s small Chromosome 4 match with Ann was on a Pouliot segment. After all that mapping, I would say that the match could not have come through Lorraine’s Pouliot side. The largest LeFevre segment between the three siblings belongs to Lorraine between 0 and 95M.

From the above analysis, I made conclude:

  • The 8.6 cM match between Ann and Lorraine is did not come down to Lorraine through the Pouliot side
  • The match is either by chance or on the LeFevre side. There are 15 names in common between Ann and Lorraine. They are all French Canadian names. My assumption would be that I could rule out a DNA match on the paternal (Irish) side.
  • Ann and Lorraine still have matches on 3 other chromosomes.

Summary and Conclusion

  • I was not surprised that this match did not match on the Pouliot side given the inter-relatedness of French Canadian genealogy
  • It was possible that this shared match on Chromosome 4 could have been from the Pouliot side, but it wasn’t.
  • It is best to not assume that a Shared Ancestor Hint and the shared DNA match go back to the same shared ancestor(s)
  • I need to build out these French Canadian lines more at Ancestry
  • The best match between Ann and Lorraine was on Chromosome 19. However, there were no 2nd cousin Pouliot matches on that Chromosome.
  • This Blog satisfied my curiosity on at least one part of the match between Lorraine and Ann and got me to map out Chromosome 4 for these 3 siblings
