That is a lot of matches, Virginia. Yesterday I tried to triangulate with some of my family's DNA matches who have the Henderson/Branson line in their tree, but haven't had luck so far. Of course, these individuals are very far back in time, which increases the difficulty and decreases the chances of figuring out the source of aT DNA matches. Still, I'll keep these matches in my Branson DNA comparison file. You never know what might turn up. Keep up the good work!
