Initial Frazier YDNA Results Show Connection to North Roscommon Frazers May Be Further Back in Time

I mentioned in a previous Blog that a Frazier has recently ordered a BigY 700 test. The first step in this test is going from his previous 37 STRs to 111 STRs. Richard’s BigY test is now at the stage where his 111 STRs have been completed.

Richard and Rick

Rick also ordered a BigY test and I am also awaiting the results of his tests. I was checking out Rick’s test and saw that he also matched Richard:

Rick matches Richard at 111 markers at a Genetic Distance of 8. That is out at the level that Rick matches two people with the Stuart surname. Initially, that seems to suggest that Richard’s match could be more distant to the Frazers of Ireland than originally thought. This has implications on Richard’s genealogy. If he matched Rick more closely, then we would be looking for Richard’s ancestors in Ireland. If they are matched more distantly, which seems to be the case, then it is likely that the common ancestor for Frazer and Frazier is in Scotland prior to the Frazer move to Ireland. At the the 37 STR level, it seemed like Richard would be more closely related to the Frazers. These 111 STRs give a more accurate level of information.

It would make more sense to show the connection from Richard’s perspective:

Richard is a GD of 7 to Jonathan and a GD of 10 to Paul. However, he is also a GD of 9 to a Stuart. What will be more important to know is Richard’s Haplogroup. That will be revealed when the results of his BigY are completed. However, based on this, my guess is that Richard’s connection should be further back than the time that my Frazer ancestors arrived in Ireland.

Here is a chart which I just saw today:

This chart was done for a different project (R-U106), so the numbers may not be the same for our R1a Frazers. However, based on the above, Richard’s most likely match with the Frazer family was a GD of 8. This translates to between 180 and 720 years. The midpoint of this range is 450 years, which is around the time-frame that I am guessing could be right for a common ancestor between Richard and our North Roscommon Frazers.

Here is the view from Jonathan’s results:

Based on my previous analysis, it appears that Jonathan’s YDNA results are more typical of our Irish Frazer ancestor. As such, Jonathan matches Richard between two Stuarts by STRs. However, as I mentioned above, what will be more important is Richard’s Haplogroup. Above, my Irish Frazer relatives are R-YP6489 and the Stuart Haplogroup is R-BY26344. That can be better seen on Jonathan’s Block Tree:

Further out, Jonathan matches a Hayes at R-YP6480. The question is, what will Richard’s Haplogroup be? My guess is that Richard could match Jonathan, Rodney and Paul with a Frazer (or variant spelling) somewhat further back than Jonathan’s, Rodney’s and Paul’s common ancestor who lived in Ireland. Further, Richard may break up the block of SNPs in the white box above starting with R-YP6489.

What Does It Mean to Break a Block?

Here is the block that needs breaking:

My Frazer relatives (Jonathan, Rodney and Paul) have five SNPs defining them all. R-YP6489 was chosen to represent this block of SNPs that defines the North Roscommon Frazers. That means that since before the time when surnames were popular, these SNPs have been collecting every 144 years or so in our North Roscommon Frazer line. We don’t know which SNPs happened first or last. Suppose that when Richard’s BigY results come in he is tested positive for three of the SNPs above, but not the other two. If one of Richard’s positive SNPs turns out to be YP6489, he will be called YP6489 and the other three Frazers will be named for one of the SNPs that Richard did not test positive for. Also, depending on the results, we should be able to figure out around what year our Frazers split off from Richard’s Fraziers/Frashers.

There is also a possiblilty that Richard’s YDNA will be more alignted with Grant and Stuart on the right. They are under BY26344. Right now, I am thinking that this possibility will be less likely.

Dating the Haplogroups from the Block Tree

In the image above, there are an average of two private variants between Jonathan, Paul and Rodney. One way to estimate the date of their common ancesor is to use 144 years per variant. That would put their common ancestor at about 244 years before their birth (say 1950) or about 1706. This is very close to when we believe that their common ancestor was born.

However, between Frazer, Grant and Stuart above, a lot more time has passed. Between YP6488 and our Frazer testers there are 7 SNPs. Between YP6488 and Stuart/Grant, there are 8 SNPs. I’ll average that out at 7.5 SNPs. Multiply that by 144 years and get 1,080 years.¬† My guess is that Richard’s results will fill in part of the gap between¬† the 11th century and 1706.

Our Frazers are documented to North Roscommon in the first half of the 1700’s. Clans associated with the Frazers by YDNA bordered each other to the SW of Inverness. By YDNA, the common ancestor of these associated clans could have been living around 1,000 AD. By family tradition, the Frazers were living in Ayrshire prior to their arrival in Ireland. It may be this time period (1600 or so) that Richard could tie into.

Summary and Conclusions

  • Richard’s 111 STR results have come in as the the first part of his BigY 700 test
  • These STR results suggest that he matches our North Roscommon Frazers more distantly than suggested by his 37 STR results
  • My guess is that Richard’s results will fill in the YDNA gap between the Stuart, Grant and others whose common ancestor could go back to about 1,000 AD and the North Roscommon Frazers whose common ancestor lived in the early 1700’s.
  • Frazer/Frazier/Frasher descendants should be expectantly awaiting Richard’s results.
  • In addition to Richard’s results, Frazers are awaiting the new BigY 700 results of Rick. Plus Rodney will be getting an upgrade from BigY 500 to BigY 700. That is a total of three Frazer/Frazier BigY 700 results we are waiting for.
