This update shows a new branch called I-BY93072, it contains two Big Y samples, one has French Canadian ancestry and the other is from Republic of Bashkortostan (Bashkiria) in the Russian Federation. Their most recent common paternal ancestor lived more than 4000 years ago.
This is a very small haplogroup: there are no known men with STR markers that match the French Canadian man. And the man from Bashkortostan has only two matches, they are from the Chuvash Republic and the Republic of Tatarstan. These men have several differences in their Y37 and Y67 STR markers and their common paternal ancestor lived several hundred years ago. Bashkortostan, Tatarstan and Chuvashia are adjacent republics in the Russian Federation, and at least two of the three men trace their paternal ancestry to Turkic peoples (Bashkirs and Tatars).
In general I-M26 is very typical of Sardinia, Spain, Portugal, France and western Europe. I-M26 is almost unknown in Eastern Europe and most of Central Europe, I am aware of only these I-M26 samples:
- there is a Jewish branch from Poland, Lithuania, Russia etc, they belong to I-PF6950
- there is an anonymous scientific sample from Greece, he also belongs to I-PF6950 but he's not closely related to the Jewish branch
- there are two samples from Bosnia and Herzegovina, they have Muslim paternal ancestry, maybe they belong to I-PF4190 which probably originated in Sardinia
- I know only one sample from Hungary/Romania, he believes he has ethnic German paternal ancestry and in fact he probably belongs to the I-Z27416 branch with some men from southwestern Germany (this branch is shown on the I-Y11222 tree linked above)
- I only know one sample from Austria and one from Bavaria, they are distantly related to each other (MRCA more than 1500 years ago?), they belong to I-BY130413 which is one of the PF4088+ CTS11338- branches
- there is one man with ethnic German paternal ancestry from Slovakia
- there is one sample from Finland, others from Poland, and Sweden, they probably all belong to I-A19395 which is also found in Germany and Great Britain and Ireland. These Finnish, Polish and Swedish men all have ancestry from areas settled by Germans or Swedes, but it's not clear how closely these men are related to each other.
If you draw a line from Venice north to Rostock, Germany, I think these are the only samples I know from more easterly regions (except for a few Swedes, Poles and Germans who don't belong to I-A19395). I-M26 is very typical of western Germany and Switzerland and the list of those samples would be very long.
This tree also shows a third sample in I-Y45584 (FTDNA calls this branch I-BY151272). Two of the samples have Big Y-500 results and one has Big Y-700 results, and we didn't find any downstream SNPs shared by only 2 of the 3 men. All three samples have Irish paternal ancestry
I-M26 is very typical of Ireland, I-M26 is much more common in Ireland than in Great Britain. But the I-M26 men in Ireland belong to many different branches of I-M26. I-Y45584 and its neighbor I-S2699 are probably the largest branches of I-M26 that are found in Ireland, and we can use STR markers to predict that many other Irish-ancestry men belong to I-Y45584 and I-S2699. But many other Irish men belong to other branches of I-M26, for example the I-PF6950, I-PF4190 and I-A19395 branches mentioned above, and many other branches.
