I have used DNAPainter to paint or map my DNA and some limited painting of my siblings. Here is my profile:
I am currently 49% mapped overall. I have mapped 338 segments and where they belong on my 23 chromosomes. The question is: why then map my siblings. It is for the same reason that siblings are testing. Each sibling inherits different DNA or different mixes of DNA from their parents. I have mapped at least one segment for three out of five of my siblings. I am missing Heidi and Sharon, so I’ll start with Sharon.
Painting Sharon
I start by creating a new map for Sharon in DNAPainter. They want to know if she is male or female, because females have two copies of the X Chromosome and males have only one.
Starting with Gedmatch
One way to start is to look at Sharon’s largest matches at Gedmatch. I want to paint matches that share a unique grandparent. I’ll start with my father’s cousin Joyce:
Joyce and Sharon share James Hartley and Annie Snell as ancestors. Joyce brings Sharon from 0% to 8% painted. The color is different than what I have on my profile for Hartley and Snell, but a light color is good for more recent ancestors. Adding my father’s other 2 first cousins brings the total for Sharon up to 12% painted.
Two Gedmatch Matches on Sharon’s Maternal Side
This brings in some more color to Sharon’s Map:
Sharon is now 18% painted overall.
Plugging Away Down Sharon’s Gedmatch Match List
Here is what I have down to Emily at Gedmatch. Emily is related on the Frazer/McMaster side:
This gets Sharon up to 27% painted. I have not yet looked at Sharon’s X Chromosome. The best place to look at X Chromosome matches is at Gedmatch, but Gedmatch is not working this morning.
Sharon’s Theories at MyHeritage
MyHeritage has a useful utility called Theories of Relativity. Here is one for Sharon:
I’ll paint in Sharon’s match to Susan under George Frazer and Margaret McMaster. Here are Susan’s matches with Sharon highlighted just under Frazer/McMaster:
Sharon and Sylvia
This gets Sharon up to 29% painted overall:
I’d like to get Sharon up to 33% painted. I split the ancestors up into the four grandparent groups.
Back to the X Chromosome
Sharon matches our Latvian cousins Inese and Anita on the X Chromosome:
This brings up an interesting point. Alexander and his brother Leo only got their X Chromosome from their Gangnus mother. That means that Sharon’s match with Anita and Inese is from Maria Gangnus.
The X is a large chromosome. When we miss that one, we miss a lot of DNA.
Sharon and Emily
The same is true of Sharon’s match with Emily:
Because Sharon’s great-grandfather was James Archibald, James only inherited the X Chromosome from his McMaster mother:
Emily gets Sharon up to 30% painted.
Sharon and Cousin Cindy
Because Sharon’s cousin Cindy is related on her father’s side, that narrows down the X Chromosome match once more:
The match between Sharon and Cindy has to come from Emma Lentz and not her Rathfelder husband:
At this point, the oldest DNA I’ve mapped for Sharon is from 1777 and the newest is from 1900.
Interesting X Chromosome Matches for Sharon on the Frazer Line
It turns out that Sharon matches Madeline and Charlotte by the X Chromosome:
Both these matches are on the right side of the X Chromosome. It looks like it would be difficult to connect the genealogy:
Assuming that this tree is right, that means that we cannot connect at the top of this chart. The X Chromosome inheritance cannot pass beyond where I have the X marks. A weak link is the wife for Archibald Frazer born about 1792. We can do some ‘what ifs’. Suppose that Archibald’s wife was the sister of my ancestor William McMaster. Then the common ancestor could be the mother of Archibald Frazer’s wife and William McMaster. There would be many other possibilities.
Sharon also matches Charlene:
I have this tree for Charlene:
Unfortunately, it is not consistent with my previous tree which has Michael Frazer as the father of my ancestor Margaret Frazer. It would be nice to be able to reconcile these trees and families.
Back to the Autosomal DNA: Sharon and Otis
Sharon and Otis match a few ways:
Otis gets Sharon up to 31% painted overall:
Sharon and Barry
I think that this tree is right. Barry is in the green and Sharon and I are in the blue:
Astrid on the Rathfelder Side
At this point, the Gedmatch matches are beginning to peter out.
Back to MyHeritage Theories and Silvia
I’ll show Sylvia on my own chart:
Sylvia’s relationship seems a bit obscure. Here is what MyHeritage has:
I’ll add her to my Biedermann tree as the Gangnus one is getting complicated:
Now that I added Silvia, I see that I was in the Gangnus tree twice, so that makes sense. After all that, I see I already added Silvia to Sharon’s DNA Map.
Ursula: A Schwechheimer Match
I’m tempted to say that Ursula’s tree is fine. Here is another possibility which brings up issues for DNA Painting:
I’ll skip painting in Ursula’s two small DNA matches with Sharon for now. I do note that her matches are near or overlapping Silvia’s matches.
Sharon and Warwick
I think that Warwick’s genealogoy is OK. The Ancestry ThruLines seem to support this Theory:
Warwick’s match with Sharon shows that her matches with Paul and Susan are on the Mcmaster and not the Frazer side.
Sharon and Bruscia
I think that this Theory left out a generation:
I have this tree, but it is not certain. I’ll go with the assumption that it is right. This small match brings Sharon up to 32% painted overall:
John on the McMaster Line
I painted a match similar to this one earlier in the Blog:
This match confirms the earlier match with Warwick. I had wanted to get Sharon up to 33% painted but she is 32%. One more percent to go.
Getting Sharon Up To 33% Painted
So far, I have used Gedmatch and MyHeritage Theories of Relativity. If Sharon has common ancestors at Ancestry that have posted at Gedmatch, then that would be a good source of mapping. The problem is connecting the two as the names very often do not match. Another was is to look at Gedmatch for people who have family trees.
Sharon and Michael and Jane
Michael is in my Frazer DNA Project:
Looks like I cut off Sharon. Michael adds a paternal segment of 20 cM on Chromosome 10. While I am on Frasers, I see Jane at Gedmatch. Sharon has basically the same relationship with Jane that she has with Michael.
Sharon and the Howorth Connection
Here is how Sharon matches Louise at Ancestry:
Sharon and Louse are 5th cousins according to this. The Howorth family is on my Hartley side. I also see Anne who I believe is Louise’s sister. I will paint them in as they are both at Gedmatch:
Ron at MyHeritage
Ron is from another catergory. His information is at MyHeritage but he doesn’t have enough of his tree down to create a Theory of Relativity there. Ron’s tree shows himself and an unknown father. Here is how Ron is related to Sharon on the Clarke side:
Sharon and Ron also have a more distant relationship on the McMaster side. Sharon and Ron are third cousins once removed. Ron should bring Sharon up to 33% painted:
DNAPainter gave the new Clarke/Spratt matchs a bright pink color. The largest match was on Chromosome 10. The match on Chromosome 16 appears to be wrong as it overlaps with a Hartley match:
There is a likelihood that small matches may be false matches. For that reason, matches under 7 cM are not used for mapping. This match was 7.6 cM.
Summary and Conclusions
- I was able to go from zero to thirt three percent painted for Sharon
- Painting the paternal side of Sharon’s X Chromosome was interesting as that is not an option that I have for myself
- Some of Sharon’s X Chromosome matches show relationships on the Frazer side that are difficult to figure out by the genealogy.
- Starting Sharon’s tree was easy but got more difficult as I got closer to 33% mapped. I had to use different techniques to find mappable matches.
- Sharon is 38% mapped paternally and 27% mapped maternally
- The key to the map shows that htere were only two Hartley ancestral couples mapped but 8 Frazer couples mapped. I think that the Hartleys had some small and/or understested families
