This project is investigating the shared ancestry of members of YDNA Haplogroup R-Z198 and its branches - including R-SRY2627, R-CTS4188 and R-L165. To join you must (a) have any of Z198+, SRY2627+, L165+ or CTS4188+ from FTDNA or Geno 2.0; or (b) have a positive result for one of these SNPs (any company) plus the Y67 or Y111 STR tests from FTDNA (NB SRY2627 is also called M167); or (c) share recent paternal ancestry with an existing project member (as indicated/supported by a close match at 37 or more STR markers); or (d) have a DYS490=10 result and be predicted haplogroup R
