Update on Frazer YDNA: Rodney’s Upgrade from BigY 500 to BigY 700

I have been writing quite a bit lately on Frazer YDNA. There are few reasons for this. One is that the information has been changing gradually as the two new Frazer Haplogroups are rolling out. The second is because the discovery of these two new Haplogroups is important. It is important not only for the four testers, but also for all the hundreds of the Frazer “Clan” who descend from Archibald Frazer who lived in Roscommon, Ireland in the early 1700’s. These new YDNA developments are equivalent to a major genealogical find. However, YDNA results are more written in stone than genealogifcal finds. Once you have your YDNA results, it is very clear that if you have these SNPs you are from these Frazer Lines and if you don’t, you are not from thse Lines.

Dating the New Frazer Haplogroups

There are a few ways to date a YDNA tree. I’ll use the dates that we think are right with Frazer genealogy where we know that.

The important dates are for the common ancestors of the four YDNA testers shown at the bottom of the tree above. Those dates are 1690, 1804 and 1836. Here I’ve put the dates on Rick’s Block Tree:

[Edit: The 1792 in the image above should be 1836.]

The tree is reversed from the genealogical tree. Rick is on the right Branch with Paul. From what we can tell, YP6489 was formed about 1200 AD. YP6489 is representative of the three SNPs in the Block. We don’t know which SNP was formed first, but we may assume that these three SNPs formed equally between the time period of 1200 and 1545. Next is the new subgroup of FT421618. This Haplogroup seems to be explained by the Frazier/Frasher test results that we are waiting for. There were quality issues, so his sample is being retested. Perhaps FTDNA had enough information to say he would be FT421618. Again, we don’t know when these three SNPs formed – just that they formed between around 1545 and 1690.

1690 is an important date as that is the date we are using for the birth of our common Roscommon Ireland Frazer ancestor – Archibald Frazer. On the James Frazer Branch, SNPs Y151390 and FT421607 had to form between Archibald Frazer born 1690 and Rodney and Jonathan’s common ancestor. That common ancestor was Thomas Henry Frazer born about 1792. On the Archibald Line, three SNPs in the Haplogroup Y85652 formed between 1690 and 1804. The bottom of the chart brings us down to the birth dates of the three testers. The private variants were formed in the James line between 1792 and the birth dates of the Rodney and Jonathan. The private variants in the Archibald line were formed between 1804 and the birth dates of Paul and Rick.

R-Y85652 – The Archibald Line

Y85652 consists of a group of three SNPs. These were previously Private Variants for Paul. In order for Paul’s three Private Variants to become SNPs, Rick had to test positive for these Private Variants and Rodney and Jonathan had to be negative for these.


Here are Rick’s results for Y85652:

The pink column is at the position on the Y Chromosome of 8162400 which is now Y85652. The T in that column shows that Rick had the mutation from A to T.

Paul had similar results:

Every horizontal line is called a read. Paul’s results go off the screen. That means that he had more reads than Rick which just means he had a higher confirmation than Rick of Y85652.

Next, I’ll look at Jonathan’s results. We expect the results to be negative:

Right at the position of 8162400, Jonathan shows no mutations from T to C. That means that he doesn’t have SNP Y85652. To satify curiosity, here are Rodney’s results:

Rodney had fewer reads, but is clearly negative for Y85652 at the position in the middle of the image above under the down arrow. If I went through this exercise for Y102792 and Y112046, I should get the same results.

Y151390 – The James Line

Here are Rodney’s test results:

He is clearly positive. Jonathan has a question mark for this position:

Jonathan didn’t have enough reads at this location. However, for all of his 7 reads, he shos the mutation from C to T at this position.

Paul aslo had a question mark at this position. Here are Paul’s results:

This was a bit of surprise. Let’s look at Rick’s results. He will have to be negative for this position for the James Line to get the Haplogroup of Y151390:

Fortunately, Rick has good results showing that he is negative for Y151390. Because Paul is in a group with Rick, Paul is presumed negative for Y151390 also.

FT421607 on the James Frazer Line

I’m curious about this SNP also. Rodney has good results:

Jonathan has only one read at this position:

But it is positive. That makes it important for Paul and Rodney to be negative for FT421607. Here are Paul’s results:

Paul’s read didn’t make it over to position #7788709.

Rick has much better results:

That means that Paul is again presumed negative based on Rick’s negative results and we end up with the James Line SNP of FT421607. FT421607 is based on only one good positive test and one good negative test. But because the negative test was already in a sold group consisting of Paul and Rick, that meant that Rodney and Jonathan had to be in the other group. The bottom line is that the James Line and Archibald Line Haplogroup results are dependent on each other.

Here is FT421607 which now appears at YBrowse listed as a new 2021 SNP:

This gives the location of FT421607 on the Y Chromosome and what the mutation was (G to T). It also gives the location of the SNP under the Frazer Haplogroup of YP6489 and the James Line Haplogroup of Y151390.

Private Variants

If it weren’t for the Private Variants, I would think that FTDNA’s manual review has been completed. However, the numer of Private Variants of the testers don’t match up with the Private Variants shown on the Block Tree. For example, Rick shows that he has nine Private Variants:

Paul shows one Private Variant:

I’m not sure why Rick has so many Private Variants. It may be because his BigY 700 covered more than the older BigY 500 tests. Their average numer of SNPs should be five. The average number of Private Variants shows three:

Rodney and Jonathan’s Private Variants (James Frazer Line)

The Block Tree above shows that Jonthan and Rodney have an average of 4 Private Variants. Jonathan shows that he has two Private Variants:

Rodney has 7 Private Variants:

This makes me wonder if Rodney actually had the BigY 700. A review of Rodney’s FTNDA history is interesting:

Rodney did have the BigY 700 done. This makes sense. However, it says that his BigY-700 was ordered 8/26/2020 and completed just 1/14/2021. I talked to Rodney’s niece who said that she did order the BigY 700. Mystery solved.

Y-HAP-Backbone Tests for Rodney and Jonathan

In addition, it looks like two Y-HAP-Backbone tests were ordered and one was completed. The one ordered on 1/11/2021 has not yet completed. Here is Rodney’s Order Status:

Here is Jonathan’s order history:

I’m not sure how to interpret what FTDNA is saying. It appears that more tests were ordered for Rodney than for Jonathan. Here is some information from FTDNA. I don’t know if itis up to date:

I checked Paul and Rick’s order history and no backbone SNP Tests were ordered there. That is interesting because it tells me a few things:

  • FTDNA is sure of Paul and Rick’s new Haplogroup of Y85652
  • FTDNA came up with Rodney and Jonathan’s Haplogroup based on one positive test from the James Line and one negative test from the Archibald Line
  • FTDNA would like more positive testing for Rodney and Jonathan to confirm their Haplogroup of Y151390, so they ordered Y-HAP-Backbone tests.

This should mean that we will have a pretty good Haplogroup for Rodney and Jonathan, that will be proven once the backbone tests have been completed.

This shows Jonathan’s pending results:

Here are Rodney’s pending results:

This seems to indicate that Rodney’s BigY700 is not yet complete. However, these are Rodney’s matches:

This seems to indicate that as Rodney matches Rick (who has taken the BigY 700) in the 800,000 level (under Shared Variants above) and Jonathan (who has taken the BigY 500) at the 600,000 level that perhaps Rodney’s BigY 700 is completed except for the Backbone test.

Another Thought on the Backbone Test and the Frazier/Frasher Results

It is possible that the need for these backbone tests came about due to the pending results of the Frazier/Frasher BigY 700 tests. At least, the tests were ordered around the time that a new Haplogroup appeared on the Frazer Tree:

This new Haplogroup which seems to be a result of the pending
Frazier/Frasher BigY results. This new Haplogroup appeared around the time of the backbone tests were ordered for Rodney and Jonathan. So these backbone tests may have been ordered to back up the new Frazier/Frasher results, to verify the James Line Haplogroup of Y151390, or both.

Summary and Conclusions

  • While looking at Rick’s new test results and the resulting new Haplogroups for the James and Archibald Frazer Lines, I was surprised to see that backbone tests had been ordered for Jonathan and Rodney from the James Line
  • Also I was surprised that Rodney had a BigY test that was only recently completed (or is being completed).
  • Now that I can see the SNP test results and the SNP results at YBrowse, it makes it easier to see how FTDNA has made/is making their decisions.
  • I can probably see the results of the testing because Rodney’s BigY 700 seems to be completed. That testing in conjunction with Rick’s recent BigY 700 testing is likely the reason why there is a new James Frazer Line Haplogroup.
  • It appears that the results of Jonathan’s and Rodney’s backbone tests should come out around the time that the Frasher/Frazier BigY 700 test results are due.
  • The result of all this testing is that we will have a really good Frazer YDNA Tree solidly documented by BigY testing.
