New Subclade Announcement: E-FT120075

 We are excited to announce the establishment of this surprise subclade by YFull! This SNP has united two existing subclades downstream E-A12313/A12255 together under a new level, not previously known in the phylogeny. These two subclades are E-A19388 and E-A20729/Y134153, and now the level E-FT120075 exists between them and E-A12313/A12255. Furthermore, a third line, E-FT120075*, exists on FTDNA. 

Thanks to our upgraders from Big Y-500 to the Big Y-700 test, as it was the increased coverage of that test that uncovered this new level of the phylogeny. 

It is a single-SNP subclade, defined by the SNP FT120075. That said, all members have the DYS385=17-17 value, so for now that value is phyloequivalent with FT120075. 

This subclade is approximately 400 years old (600 - 175 ybp @ 95% confidence), being around a century younger than its parent E-A12313/A12255. This date corresponds perfectly with known historical population growth for Ashkenazi Jews in Central and Eastern Europe. To date, all known members have genealogies going back to Eastern Europe, specifically Poland, Ukraine, Belarus, and Lithuania. 

E-FT120075 is associated with the DAA01 subgroup in our project subgrouping here. All members this group are confirmed for FT120075, either by a test themselves or by genealogical relation. 

E-A12313/A12255, because of a members' genealogy back to the mid 1600s in the Rhineland, is thought to have originated there, around 500 years ago according to YFull (700 - 300 ybp @ 95% confidence). However, given that this subclade is 100% EAJ and at least a few generations younger than E-A12313/A12255's MRCA, it is reasonable to suggest that E-FT120075's MRCA lived outside of the Rhineland. However, whether the MRCA lived somewhere like Silesia, Bohemia, Poland, or another place is unknown. All known genealogies within E-FT120075 only trace back to the 1800s, and not much is known about the paths members' ancestors took to get where they were back then. 

As always, thank you for your support of our project!
