I have written previously about the Frazers from Ireland and those who have tested their DNA who are descended from those ancestors. In 1749 this Northern County Roscommon Frazer family looked like this:
If you click to make this larger, you will see the 2 Frazer lines which our testers are descended from (Archibald and James). As an added bonus, you see their likely mother, a widow Mary. So far, I’ve written about the Archibald line. This blog will be more on that line.
Recently, Michael’s autosomal DNA test results have come in from England. I would have thought that his results would clear everything up. Well, they did enforce previous conclusions, but have also created some more questions. As I tried to map out the relationships for the various testers, I think I see the reason why. There were a lot of Frazers cousins who married each other back in the day. There was a famous poem I’d like to modify to: Higamus, Hogamous, Frazers endogamous. What is endgamous? These are groups of people who married relatives due to several reasons. Some examples are the Ashkenazi Jews, the Amish, Colonial Americans and others. The Frazers as a protestant minority had few marriage choices in their area of Ireland if they wanted to marry other protestants. Some Frazers did get around this by marrying Roman Catholics (called Papists in the 1749 Survey).
This is what my Archibald line looks like. For simplicity, I’ve left out a few lines.
The relationships on the above chart range from 3rd cousin, once removed to 6th cousins. I’ve lopped off 3 or 4 of the more recent generations for privacy. My line is blue, but the way I have it, James Frazer married Violet Frazer. They are first cousins, so I could’ve had 2 sets of blue boxes. I have Bill from Canada in the same group on the left in yellow as being descended from James and Violet Frazer. He also is descended from another cousin, Ann Frazer born about 1807, shown on the right in yellow. This means our best guess at his genealogy has him with 3 Frazer ancestors. Jane from Colorado is in the green line but has an extra Frazer/Fraser ancestor also named Jane born 1846. We can’t quite place this extra Jane, but my guess is that she is descended from the John on the far left. We are still waiting for the DNA from Ros from Australia. Her line is in purple above and seems to be the only one so far who doesn’t have multiple Frazer ancestors.
Here is what the DNA tester’s Chromosome 1 results look like in a spreadsheet:
These 4 people form a super Triangulation Group. I mentioned in a previous blog where 3 or more match each other they form a Triangulation Group. This triangulation will represent a common ancestor or likely a common ancestral couple. In this case that couple is at the top of the chart above. That is the place where all these people merge. The couple is Archibald Frazer and Mary Lilley (or Lilly, I can never remember which). The numbers in green are pretty huge. I wonder if other families have such a large match representing a couple that far back (mid 1700’s). HHM is my sister Heidi. This same Chromosome 1 DNA didn’t make it to me. Also Bill got less of this extra dose of DNA.
Sorry, More Numbers
Above are where the Archibald Line DNA testers match each other on other Chromosomes. Chromosome #12 in purple is the other Triangulation Group. Notice that Michael (MFA) didn’t make it to this group. He should have, but that DNA dropped out like mine did for Chromosome #1. The other Chromosome matches don’t have Triangulation groups, so these are less certain as to predicting common ancestors. I tried to guess what these matches may represent as far as common ancestors on the right side of the spreadsheet above.
What Did I Learn and What Are My Further Questions?
- I need to read up more on endogamy and how that effects DNA
- The Archibald Line has 2 Triangulation Groups so far that represent a couple from the mid 1700’s. There are no Triangulation Groups from more recent Frazer ancestral couples. This is likely because we have more descendants from the earlier couple to triangulate on than on the more recent couples.
- Usually matches representing more recent ancestors should have higher cM numbers. Here the older ones are higher. Is this due to endogamy?
- The other line (James Line) testers don’t have the same high number matches but also don’t have any Triangulation Groups yet. I assume this is due to a lack of intermarrying.
More will be revealed and I plan to write more blogs as more DNA testing results come in.
