I am curious about the labels that are being used to describe the three groups. How are they being derived?
Group 1 Slovakian (B1600, 177636)
Group 2 Mizrachi/Middle East (302467, 194747, 220642, 264819)
Group 3 Ashkenazi (7568, N112631, N50322, 65829, 250837)
I simply made up names from the obvious ancestral geographies.
Group 1 ancestors are Eastern Slovakia.
Group 2 ancestors are mostly Iraq and Iran.
Group 3 ancestors are mostly Eastern Europe (Pale).
My hypothesis is that Group 1 represents descendants of an early split from an original Asian R2a F1159+ and F3604+ group (perhaps before there were any Jews). Group 2 represents descendants of one or more Babylonian Jews with the additional SNPS F1092+ and F1758+ (perhaps converts, perhaps exiles from 2500 years ago, impossible to say). Group 3 represents descendants of one person or a group of people that left the Middle East and went to Western or Eastern Europe and assimilated into Ashkenazic communities, developing additional STR mutations along the way (and probably additional SNPs).
When the two BIG Y results come back (yours and my cousin's) we will see how many SNPs there are in common between those two kits and how many there are that are unique. I have no doubt that there will be common SNPs that can help differentiate between Group 2 and Group 3 Jews (just as they can be differentiated now with STR values).
All mostly guesswork on my part. I listened to the FTDNA webinar today on BIG Y. There will be a new haplogroup tree developed shortly from all the BIG Y results and the Geno 2.0 results, after some analysis of the hundreds of novel BIG Y SNPs that will be found. The most useful thing to do down the road is to get someone from what I am calling Group 2 to test for BIG Y to see how the SNPs line up between Group 2 and Group 3. We already know that F1092 and F1758 differentiate Group 1 kits from Group 2 and 3 kits.
