More Irish Frazer Autosomal DNA

After a bit of break, the autosomal portion of the Irish Frazer DNA project is roaring into action. This is thanks to Pat who had her cousin Susan test. Pat also gave a boost to the Frazer YDNA by having Susan’s brother Rick test at the 67 STR level. The YDNA portion of the Frazer DNA project has been chugging along and needs an update, but I last wrote on the Autosomal side in March 2017 when Doug’s Aunt Rita was tested from the Frazer/Stinson Line.

Susan’s Genealogy by Richard Frazer

It is always good to start with the genealogy to see where Susan’s DNA is coming from:

A few notes:

  • This chart only those who descend from Richard Frazer and have tested for DNA
  • David is in white. His line was added based on DNA and the fact that we had an extra James in the genealogy. However, I am not sure David is sure of this placement.
  • Jane was also added by DNA, but her placement here seems more secure.
  • Rick has only taken the YDNA DNA test and not the autosomal.
  • Those in the yellow and blue lines descend from two Frazers: Violet and James. Violet is the daughter of Richard. James is not well documented. I have him as a first cousin to Violet and a son of Philip (brother of Richard). However, this has not been proven.
  • I would like to be able to pull apart the DNA of James and Violet for analysis. It seems like this could be possible by comparing the yellow/blue lines who descend from James to all the other Frazer descendants.
  • Both Jane and Michael are also in the Archibald/Stinson Line

DNA on the Richard Frazer Line

The autosomal matrix for the Richard Frazer descendants looks like this:

The area in the dark box represents those that are descended from James and Violet Frazer. The DNA that they got from Violet and James is at the intersection of the Richard Paterson Frazer (RPF) Line and the George William Frazer (GWF) Line. So for example, Susan from the RPF Line shared from zero to 73 cM with those in the GWF Line (Heidi through Paul). The highest amount shared was between Gladys and Sharon. That means that it appears that Gladys and Sharon each have 86.9 cM of DNA in them from James and Violet Frazer. Here is what their match looks like:

Of these matches, I already had Triangulation Groups (TGs) on Chromosomes 9 and 12, but the TG on Chromosome 18 is new. More about those in the next section.

The Frazer TG Matrix

I have been keeping track of the TGs that I have found. I found some new TGs:

I took out the pink George Frazer/Price TGs that I had in a previous TG Matrix to save room.  Perhaps they should be in a separate chart. However, I see that there are still some TGs that could be George Frazer/Price TGs. These are the ones that only have matches with Bill, Pat, Susan, or Gladys. These are TG09A and 09B. Also TG10A. In addition, it appears that I should be able to combine TG09A and 09B. The yellow TGs are interesting to me. They just have people from the first two groups in them, so they could represent James Frazer or Violet Frazer. TG18C in yellow was new based on Susan’s results.

Actually, when I look at the matches, Heidi should be in the matrix also, so I need to fix my matrix. There are a lot of details in doing this and sometimes I miss things:

Susan’s Genealogy by Archibald Frazer

Susan also descends from Archibald Frazer who married Ann Stinson.

Here we see that Jane and Michael who were in the Richard Frazer Line are also in this line. Based on Susan’s matches, we should be able to tell which line the matches are from:

Let’s Look at the George Frazer/Price group:

  • Where they just match my family, I have them in yellow. That means that this could represent DNA from James and Violet Frazer.
  • Where they match each other, that could indicate DNA from George Frazer or his Price wife. Examples of this would be TG9A, TG9B and TG10A. These should probably be in pink.
  • Where this group matches just Michael or Jane, we can’t tell if the match on the Richard Frazer or the Frazer/Stinson Line. See TG03C and TG04B
  • In TG05A, Pat and Gladys are in a TG with Cathy from the Stinson line. This puts their common ancestor at Archibald Frazer or his wife Ann Stinson.

Comparing All the Frazer DNA

When I look at all the Frazer DNA, I see this:

This is quite small, but it does tell by how many cM each Frazer descendant matches each other Frazer descendant. One thing that stuck out to me on the chart is that Jane and Vivien match each other at about 110 cM. On the Archibald/Stinson genealogy chart, they show as 3rd cousins to each other. A typical 3rd cousin would share about 74 cM, but the range is 0-217. For example, Cathy shares 34.8 cM with Jane and 31 cM with Vivien and she should be a third cousin with those two. On the other hand, Michael is 4th cousins with Rita and Vivien and shares more DNA with those two than the 3rd cousin relationships I just mentioned.

Susan’s largest match outside the Frazer/Price line is with me:

This is quite a bit considering we are 4th cousins on paper. This is a little over twice the typical amount that 4th cousins might share. My brother Jonathan makes up for it by sharing no DNA with Susan.

Mapping my family’s chromosome 7

Here is what my Chromosome 7 looks like compared to my sisters Heidi and Sharon. This raw data phasing was done by MMacneil from Canada.

I got brighter red Frazer DNA from my father’s mother. This is where I match Susan. Notice that Heidi and Sharon got their paternal side DNA from their Hartley paternal grandfather instead of their Frazer maternal grandmother at the beginning of the Chromosome where I matched Susan.

I should be able to phase myself against my brother Jonathan and sister Lori also at Chromosome 7:

It wasn’t as easy as I thought because what looked like a crossover for me at position 70 was actually a crossover for Lori and Jonathan. All this to show why Susan has a smaller match with Lori than with Joel. It has to be smaller because the DNA that Lori got from her dad switched from his mom’s Frazer side to his father’s Hartley side at position 28.

The Bigger Picture

I alluded to it before, but Susan and her Frazer/Price relatives appear to descend from three Frazer brothers. As such, they would have quite a bit of the DNA from Archibald Frazer and Mary Lilly:

For example, one child gets 50% of the DNA that the parents had. Add a child and it is up to 75%. I would think that with three children, that number would be up to 87%.

Summary and Conclusions

  • Susan’s DNA has added to our knowledge of the Frazer family – especially on the Archibald side.
  • Her results have also helped in the mystery of the James Frazer/Violet Frazer marriage.
  • It would appear that the matches to Susan and her Frazer/Price relatives that aren’t shared by other Richard Frazer descendants would more likely be James Frazer (b. about 1804) matches.
  • A new look at the Frazer matching DNA matrix has shown some high matches between specific people. This leads us to wonder who was the wife of Richard Frazer (b. about 1777).
  • Next up, I’d like to get back to the YDNA. More results are coming in from people related distantly to the Frazers. In addition, there should be a new update to FYull’s Ytree and updates to other genetic trees related to the Frazers.
