My cousin took the Y-37 and was placed in the following category:
E-Z827>Z830>PF1962>M123>M34>M84>CTS1096>Y14899>Y1489 1>8970404 (and 21089706) [Cluster B6939] DYS448=19 and DYS520=20-assumed.
Short of a couple of SNP's that FTDNA doesn't offer (and I can't test this cousin again for processing at another company), the project administrator pushed the Big Y.
Is there anything else I can do to refine this without upgrading to the Big Y? I'm working on several lines and it's not in the budget.
Also, I've read papers written by A.A. Aliev and D.L. Tartakovsky about Ashkenazim and E1b1b1c1a. Can you point me to something more recent based upon the results that will help me understand the migration pattern.
