The New Haplogroup has been Reported by FTDNA

It is official. As of today my haplogroup is R1b1b2a1b5 as expected (and hoped for). That is consistent with all of my best matches at 37 and 67 markers.

Initial Deep Subclade Results

As mentioned in the previous update, FTDNA is testing me for six additional SNP's.
Results on two of the six have been received about a month before their target dates.
They are L49 and L23. I know it is a bit like watching grass grow, but the result was positive on both and my haplogroup has changed from R1b1b2 to R1b1b2a. Another
man of Irish descent has tested positive on all six of these SNP's which came as a big surprise to me, because I had assumed that at least some of them would be mutually exclusive. So, like that man, my results when they are all in could well be the same as his are, R1b1b12a1b5. That is the most common of the R1b haplogroups so I guess that makes me a man of the people.

Looking Farther Back than the first McCown

As many of you know, there is more to Y-DNA testing than just finding your score on
12, 25, 37 or 67 markers or locations on the male Y chromosome. There are also groupings called haplogroups. If you match someone in all 67 markers but are in a different haplogroup you are not related by a common ancestor.

My major haplogroup is R1b but that is further divided into clades and subclades. After testing for my haplogroup, it turned out to be R1b1b2. It stayed that way even after having deep sub clade tests. But now, FTDNA and the science of DNA genealogy have discovered "new" sub clades and my DNA specimen is now being tested for the following Single Nucleotide Polymorphisms (SNP): L21, L23, L49, P310, P311 and P312. Now, if I am truly related to my highest quality matches, my new haplogroup will be R1b1b2a1b5. So, that will validate all these high quality matches.

R1b1b2a1b5 is present in several countries in Europe, Africa and Asia, but it's highest concentration per capita is in the British Isles and there, more specifically in Ayrshire, Argyll and the inner Hebrides in Scotland and in Ulster.

Not many of my best matches have been tested to this level, but those that have are
R1b1b2a1b5. The result will be known on all of the SNP's except L21 on August 19th and SNP L21 is expected on August 24th. You will see the results on the website. Navigate to that page, then click on DNA Test, then on Test Results and then scroll down the left hand margin until you come to the heading Mag Uidhir II (Maguire II). Look for Lawrence McCown under that heading. There are two of us under Lawrence, mine is the first one. The tension mounts.

One last thing, you don't have to be a by-stander, during July only, FTDNA is offering good discounts to new test subjects who join under a surname group such as the McCown Surname Group. There is probably a surname group for your surname, but if not, they will help you start one and you still get the discounts. See and sign up for the most markers you can afford or maybe more.
