It took me a while to figure who Katherine was at 23andMe. Here is how Katherine and I match by DNA at 23andMe:
Here is what 23andMe says:
Katherine and I should be in the range of third cousins. Fortunately, Katherine posted a photo at 23andMe. After looking at Facebook photos, I found some that were the same as Katherine’s photos at a Frazer Family Facebook page we are both on. The mystery is solved.
Here is how I show Kat on our Frazer tree:
I recently wrote a Blog on Rebecca and our match at AncestryDNA. So it has been good to find these Frazer DNA matches. My blog on Rebecca showed that I matched her more on the McMaster side than the Frazer side. This was not surprising as our common ancestor Margaret McMaster had two McMaster parents. Also Kat’s grandfather James Robert Frazer born 1927 married a McMaster. The advantage of Kat’s test compared to Rebecca’s DNA test is that I will be able to see how Kat and I match on specific chromosomes.
Painting Kat’s DNA Match
There is a web tool called DNA Painter that I use to show where my DNA matches are. Here is my current DNA Map:
This shows my paternal and maternal sides. My Frazer matches are on my paternal side. This shows I am 41% painted overall. I circled some of the areas that Kat could match me.
Here is just my paternal side where I am mapped at 50%:
I have a lot of green as I have a lot of Hartley 2nd cousins.
Adding Kat to the Mix
Kat got my DNA mapping up a percent from 50% to 51% on my paternal side. I mapped our DNA matches to “Frazer McMaster 1838” because that is where our shared DNA comes from.
Next, I’ll expand Chromosome 19 as that is where our largest match is:
Kat’s match with me in maroon overlaps with Keith’s match with me in blue. Keith has McMaster ancestry. That means that my match with Kat on Chromosome 19 is from the McMaster side. But which McMaster? For that we have to look at Keith’s genealogy.
Keith descends from Fanny and James McMaster. That means that the DNA that Kat and I share on Chromosome 19 must be from Margaret McMaster. For simplicity, I didn’t make a new box for Kat as Kat and Rebecca both have similar genealogy. Here is Margaret McMaster on the left who married George Frazer :
Because I know something more specific about this DNA, I’ll make a new category for Margaret McMaster’s DNA.
I added a dark green for Margaret McMaster’s DNA.
Emily’s McMaster DNA
The reasoning is the same for Emily who matches me on Chromosome 19, but the common ancestor goes back another generation:
This match with BV seems to indicate that the DNA is coming down from the McMaster side. BV also has Frazer ancestry, but that Frazer connection is too far back in time to consider.
My Chromosome 1 Match with Kat
Most of my paternal Chromosome 1 matches are on my Hartley side:
That explains why I don’t have room for a larger match with Kat. I can’t tell if my match with Kat is Frazer or McMaster, so I’ll leave it maroon which means it could be either.
Here I have a pink arrow pointing to my match with Kat. Right below Kat is a match with my cousin Paul and I have that as a George Frazer DNA segment in yellow. If I did that right, then my match with Kat also came from George Frazer. My reasoning is based on the two blue matches. They are from Susan and Ken:
Susan and Ken are related on the Frazer side. That means our overlapping segments came from the Frazer and not the McMaster side.
Here I have turned the match that I have with Kat from maroon to gold to indicate that it is a Frazer match. Right after that I have two blue matches. That represents a crossover that my father had from his mother. My dad’s mother had a Frazer father and a Clarke mother. Where I have the arrow pointing represents the change from Frazer to Clarke in the DNA that my father got from his mother and passed down to me.
Chromosome 10 – More Frazer DNA
Here is Michael:
This DNA comes down from Richard Frazer to his daughter Violet Frazer. I don’t want a new entry for Violet, so I’ll say that this DNA is from George Frazer. However, the DNA Kat and I share is actually from George’s mother Violet Frazer.
Chromosome 12 gets a little tricky, but it looks to be McMaster DNA for sure:
The first maroon match is with my cousin Paul. The second maroon match is my match with Kat. The purple match is with BV. BV had that small match with Emily on Chromosome 19 above. I have the other two pink matches going back to Abraham McMaster born in 1764. There is a lot of confusion about McMaster genealogy and how all lthe McMasters fit together. This cluster of matches may be a hint to unravel that confusion.
For right now, I’ll sign over to the two maroon segments to Margaret McMaster DNA (green segments):
I also showed some of the detail of my match with Warwick and our common ancestor of Abraham McMaster.
Here is Kat’s summary from DNA Painter:
- The maroon is George Frazer or Margaret McMaster DNA
- The yellow is George Frazer DNA
- The green is Margaret McMaster DNA
Kat and I have a lot more McMaster and Frazer DNA, but this is just where our DNA intersects or matches.
Summary and Conclusions
- The fact that Kat tested at 23andMe made it easy for me to see where we matched, and by how much on each chromosome
- Once I added Kat’s matches to my other matches using DNA Painter, I could see whether our match was on the Frazer side or McMaster side for each segment where we matched.
- One match that I had with Kat and descendants of Abraham McMaster may be a clue as to how Abraham McMaster fits in with the other McMaster genealogy.
- If Kat uploads her DNA results to Gedmatch.com, she will be able to see how she matches other Frazer descendants by DNA.
