In my previous Blog on Effie<\/a>, I looked at some possible parentage. In this Blog, I’ll get into some genetic genealogy, looking at the DNA of Effie’s great-granddaughter, Jean. Jean recently uploaded her Ancestry results to Gedmatch for comparison.<\/p>\n

Effie’s Possible Ancestry<\/h2>\n

Based on reasons I presented in my previous Blog, it seems like Effie’s grandparents should be William McMaster and Margaret Frazer. Here is a pre-Effie tree that combines DNA-tested descendants of William and Margaret McMaster with an ancestry chart:<\/p>\n

\"\"<\/a><\/p>\n

I had guessed that Effie was the daughter of Isabel McMaster who should fit in on the second row above. I note that Jean told me that she matches Keith by DNA. So that is further evidence that Jean and Effie may belong on this chart.<\/p>\n

\"\"<\/a><\/p>\n

Here I entered Jean’s line in a different color as we are still figuring this out.<\/p>\n

Jean and Keith<\/h2>\n

It turns out that Jean is Keith’s fourth highest DNA match and my brother Jim is Keith’s fifth highest DNA match at Gedmatch. Here is how Jean and Keith match:<\/p>\n

\"\"<\/a><\/p>\n

The DNA doesn’t tell who the common ancestor is, but suggests that Jean and Keith have a common ancestor. On the chart above, Keith and Jean’s common ancestors are 5 generations away. Gedmatch is guessing that the common ancestor could be as close as 4 generations away. By the chart above, if I am right, Keith and Jean would be 4th cousins.<\/p>\n

By comparison, here is where Keith and my brother Jim match:<\/p>\n

\"\"<\/a><\/p>\n

If Jim, Keith and Jean all matched on overlapping areas, then we could say that the three triangulate and share the same common ancestors. However, the fact that they don’t all match on the same segments doesn’t mean that they don’t share common ancestors. Sounds confusing, I know.<\/p>\n

Jean and Emily<\/h2>\n

The next person I recognize on Jean’s DNA match list is Emily. Here is how they match:<\/p>\n

\"\"<\/a><\/p>\n

Jean and Paul<\/h2>\n

Jean has a smaller match with my cousin Paul:<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

None of my family has DNA matches with Jean but that is not unusual for a 4th cousin once removed. However, one could say that we are related in the sense that Paul and Emily are related to Jean as my siblings and I are 2nd cousins once removed to Paul and Emily.<\/p>\n

BV – Descendant of Mary Ann McMaster<\/h2>\n

BV had uploaded her results to Gedmatch, but now I don’t see them. It could be that there was a problem with the results or a private button was turned on. I wrote a Blog about BV’s DNA here<\/a>. It’s too bad that those are missing as I would have liked to have seen how Jean matched BV. Right now the only DNA uploaded to Gedmatch is from Jean and descendants of Fanny McMaster.\u00a0[However, see below in the Blog.]<\/span><\/p>\n

Jean and the X Chromosome<\/h2>\n

Jean probably would be a good X Chromosome match with others, but her X Chromosome DNA did not get uploaded to Gedmatch. The reason that she would be a good match is that the X Chromosome is never inherited by a son from the father. So for example,<\/p>\n

\"\"<\/a><\/p>\n

The places that I have red boxes, show where there cannot be an X Chromosome passed down. This means that BV can match Jean, my sisters,\u00a0 or Emily by the X Chromosome. In order to show this, we would need to get BV’s DNA back up on Gedmatch and get Jean’s X Chromosome results to Gedmatch.<\/p>\n

Jean’s Matches with Frazers<\/h2>\n

I have a Frazer DNA project, so I’ll check some of these people to see if Jean mathes any of them. Here Jean matches Cathy:<\/p>\n

\"\"<\/a><\/p>\n

Here is Cathy’s tree as it relates to the Frazer family:<\/p>\n

\"\"<\/a><\/p>\n

Jean and Cathy’s common ancestors could be Frazer, Stinson, Parker, Moore, or someone not even on this chart. Cathy is on the Archibald Line of the Frazer family. The best guess for Jean’s ancestor Margaret Frazer is that Margaret is on the James Line of the Frazer family.<\/p>\n

Jean and Jamie<\/h4>\n

I found a small match here:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Jean and the James Line of the Frazers<\/h3>\n

Here Jean matches Toni:
\n\"\"<\/a><\/p>\n

Here is where Toni is on the DNA\/genealogy chart for the James Frazer Line:<\/p>\n

\"\"<\/a><\/p>\n

This means that if I Margaret Frazer placed right and Toni placed right, they would be on opposite sides of the James Line Chart. That means that Toni and Jean would be about 6th cousins, or something may be wrong in the chart. The other possibility is that they match on a\u00a0 different line.<\/p>\n

Rodney and Jean’s DNA Match<\/h4>\n

\"\"<\/a><\/p>\n

Here is Rodney on the Chart:<\/p>\n

\"\"<\/a><\/p>\n

All the same caveats are in effect for this match that were in effect for Jean’s match with Toni above.<\/p>\n

Frank and Jean<\/h4>\n

\"\"<\/a><\/p>\n

I’m looking for trends here. So far the trend is that Jean is matching more Frazers on the James Line side as compared to the Archibald LIne.<\/p>\n

\"\"<\/a><\/p>\n

Here Frank shows as a closer relative to descendants of Margaret Frazer based on where I have her placed in the tree.<\/p>\n

Keith and Jean<\/h4>\n

I already mentioned Keith above.<\/p>\n

\"\"<\/a><\/p>\n

However, above, I was thinking about the McMaster side. The assumption is that Keith and Jean match on the McMaster and Frazer sides, so we wouldn’t know which side the matches above are on.<\/p>\n

Barbara and Jean<\/h4>\n

It’s a good thing that I went through my list twice, as I missed Barbara the first time:<\/p>\n

\"\"<\/a><\/p>\n

Finding BV<\/h3>\n

It turns out that the Barbara above is actually the BV I was looking for. If I search for BV at Gedmatch by her kit#, Gedmatch tells me that there is no such kit. But if I put in her kit number into Gedmatch for comparison, I can find matches. This is the missing information that I was looking for.<\/p>\n

\"\"<\/a><\/p>\n

Based on the proposed tree, BV and Jean are third cousins, once removed.\u00a0 Based on Gedmatch’s best guess, BV and Jean have a common ancestor 4.4 generations away. William McMaster and Margaret McMaster are 4 generations from BV and 5 generations from Jean. That averages out to 4.5 generations. Seeing as a common ancestor would never be 4.4 generations away, that is pretty close.<\/p>\n

Triangulation, Crossovers and Chromosome 8<\/h4>\n

If BV, Jean and Emily each matched each other on Chromosome 8, that would be a strong indication that they each received that DNA from the same ancestor. However, look at what happened. BV and Jean match each other on Chromosome 8 between positions 57M and 71.\u00a0 Emily and Jean match each other between positions 71 and 104M:<\/p>\n

\"\"<\/a><\/p>\n

This could indicate a crossover. A crossover is where the DNA we inherited from one ancestor cross over to the DNA we inherited from the spouse of that ancestor. In this case, the crossover could be between William McMaster and Margaret Frazer. Our crossovers are inherited from our grandparents. So, if this is a crossover between William McMaster and Margaret Frazer it would be a crossover that came down to BV or Jean either through Elizabeth Shannon or Effie McMaster.<\/p>\n

Here is Elizabeth:<\/p>\n

Here is Effie:<\/p>\n
