TERRIOT Surname DNA Project
All of the first eight participants have matches; two with 12/12, and four with 25/25. One other has a slight mutation on each of two markers; the eighth matches 24/25. We hope to have more tests pinpointing the individual line where these mutations first occurred.
The TERRIOT haplogroup predicted by the testing company, based presumably on the French origin of the common ancestor, is R1b1b2. As of 2010, there were 21 submitters in our project, all but one related, but with some lines distinguished by identifiable mutations.
