Ah, good. So far I also think your Thomas 1807 was a son of Thomas 1760, who is R14 in my database. It will be nice if we can get a descendant of his other sons, to see if you match. I'm very interested to see if you match my branch, too. I suspect that the western NC Rigsbys were from the immigrant Thomas, and that the central NC Rigsbys were from immigrant James.
I have now set up the project at Family Tree DNA. Apparently they have changed the rules since we started the Hinds project, as it seems we don't need 6 people to get started. You can go ahead and get your kit by visiting this page:
