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 Easter...

New Subclade Announcement: E-A22300

After a long while, we are finally able to announce the establishment of the subclade E-A22300 on YFull! This subclade is downstream E-Z36149, technically also downstream E-BY20365.  E-A22300 has been established on YFull by two Big Y testers, as well as a sample from PGP, an open-source scientific initiative. Many thanks to these individuals for their help! It is a three-SNP subclade, defined equally by having the SNPs A22300, A22301, and A22302.  This subclade is one of the youngest on YFull, with an estimated TMRCA of only 150 ybp (475 - 75 ybp @ 95% confidence). Considering there is a genealogy in the lineage traced to the early 18th century in Germany, the TMRCA has to be at least 300 ybp. Given the historical narrative, as well as multiple WAJ members of this subclade, we predict that the MRCA of this subclade lived somewhere in modern Germany, specifically the Rhineland.  E-A22300 is associated with group A00 in the project subgrouping here . If your kit is in this...

New Subclade Announcement: E-BY142197

Connected to our work on the E-Z36149 Geographic Census, we are happy to announce the establishment of two new subclades within E-Z36149, the first being E-BY142197. This subclade is technically downstream E-BY20365, although the phylogenetic importance of that SNP is not yet determined.  As always, we appreciate our subclade-defining members for helping us in this discovery, this time with two Big Y testers and one SNP tester. Many thanks! It is a single-SNP subclade, defined by the SNP BY142197. This may change when another Y-700 or WGS test is added to the subclade.  E-BY142197 looks to be the oldest known subclade of E-Z36149, with a TMRCA of c. 650 ybp, which is the same as its phylogenetic parent and grandparent. It is unlikely that it is quite that old, given that some generations would have had to exist between E-Z36149 and E-BY142197's respective MRCAs, but we can assume that this was an early split-off from the root.  The subclade is associated primarily with th...

Results of the E-Z36149 Geographic Census

Hello, Continuing from the success of our E-Y17357 Geographic Census, the E-Y14891 (AB-005) Project is happy to announce the results of our E-Z36149 Geographic Census ! A survey was sent out to E-Z36149 members (confirmed or predicted) on FamilyTreeDNA asking for genealogical and geographic information for members’ most distant known ancestors (MDKA) on their paternal lines. We combined the results of that survey with member-submitted data already present on FTDNA to attempt to reconstruct the history and spread of E-Z36149.  E-Z36149 is an interesting subclade for a few reasons. 1) Its size. E-Z36149 makes up over a quarter (185/659 = 28%) of all E-Y14891 members on FTDNA! 2) Its age. E-Z36149 is only around c. 650 years old! (850-475 ybp at 95% confidence) 3) Its geographic spread. E-Z36149 has a very high percentage of Western Ashkenazi Jews (WAJs) relative to Eastern Ashkenazi Jews (EAJs).  Please note that: 1) This is a map of ancestor locations, mostly in the early-to-mi...
