This project is dedicated to a small subset of I1-P109 Haplogroup individuals who have the STR mutation DYS-455=9. This group is further split by YCAIIb. The EDMUNDSON-GRANT-THORNTON group is YCAIIb=20, while others are YCAIIb=21. The goal of this project is to use this unique signature in conjunction with novel SNPs to trace the migration of this clan within Europe. In order to join this project you should be positive for the SNP I1-P109 and be DYS-455=9.
