Recently I was made the Group Administrator for the Courtney Surname Project at Family Tree DNA. Currently we have 17 members who have submitted samples for their male line Y-DNA. My goal is to get enough members to sort out the five or six major lines of the Courtney family. If we were able to obtain results for Cournane / Courtney from County Kerry, Ireland, McCourt / Courtney from Ulster, Ireland and Courtenay from England it would go a long ways to understanding our heritage.
