An Update on Stan’s Frazer DNA at 23andMe

Last year I wrote a Blog about Stan. Here is how Stan and I are related:

Stan and I are second cousins once removed. At the time that I wrote the Blog, Stan did not have the option to share his DNA. He has since changed that and I can see how much DNA we share with each other:

This shows that we share a total of 53 cM on three different chromosomes. Here is how that works out between my match with Stan and his sister Brenda:

This shows that Brenda matches me a bit on Chromosome 5 where Stan doesn’t and that Stan matches me on Chromosome 10 where Brenda doesn’t.

Painting Stan

I use a utility to paint my DNA matches onto my chromosomes. The DNA that Stan and I share either came from George William Frazer born around 1838 or his wife Margaret McMaster. The DNA that I am most interrested in is on Chromosome 10:

On the right hand side, Stan fills in a missing gap. Here is the key:

In general, the maroon is DNA from my Frazer grandmother. The green is the DNA from my Hartley grandfather. They were married. However, the right side shows more detail. The red match on the right with Michael goes back another 2 generations:

Now this gets into how much we want to assume. Unfortunately, I don’t have a wife’s name for Richard Frazer at the top. However, we know that his daughter was Violet Frazer. She married James Frazer who we believe to be Violet’s first cousin. That means that for me, this red DNA would have come from Violet Frazer. Then before that, it either came from Richard Frazer or his unknown wife – we don’t know which.

Then at the very end of Chromosome 10, I have a match with Ron. That is a match on my Clarke side. Clarke is believed to be unrelated to Frazer, but married my Frazer great-grandfather.

So how does Stan fit in? It is possible that Stan and I share the DNA from James Frazer. He married Violet Frazer and was his first cousin. Confusing, isnt’ it? However, this is interesting to me as the James Frazer genealogy is more difficult to document than the Violet Frazer side. I believe that the father of James Frazer was Philip Frazer. I will keep that in mind in case I find another descendant of Philip Frazer who matches in that same segment of Chromosome 10. The reason why I think that Stan’s DNA may come from Violet’s husband James is because there is no overlap with the DNA that came from Violet.

How Much Am I Painted?

I don’t know if Stan’s DNA match brought my numers up, but here are the current numbers:

It would be nice to be up to 50% identified. To do this I will likely need to find more maternal DNA matches. Here is the percentage of my paternal paintedness:

Stan matches me on my paternal side.

Chromosome 6

Here is just the beginning of Chromosome 6 where I match Stan:

Brenda and Stan overlap with Ken and Doreen. Ken and Doreen descend from the brother of my 2nd great-grandfather. That means that the DNA that Stan and I share must come from my 2nd great-grandfather who was George Wiliam Frazer born about 1838.

 Chromosome 7

Here I have the whole Chromosome represented. Stan shares DNA with Marilee. One great thing about DNA Painter is that it can handle matches with different companies. Marilee tested at MyHeritage and Stan at 23andMe:

That means that Stan and I likely share DNA from Violet Frazer on Chromosome 7.

Summary and Conclusions

  • Thanks to Stan sharing his DNA at 23andMe, I can see where I specifically match him, that is on which chromosome and on which part of which chromosome
  • The placement of the matches is important because they represent different ancestors. In this case, the different ancestors are likely different branches of the Frazer family. This is because my third great-grandfather who was a Frazer apparently married his first cousin who was also a Frazer.
  • Stan’s DNA match with me helps confirm both my Violet Frazer genealogy which seems more solid and my Philip to James Frazer genealogy which is more shaky.
