I haven't visited these boards in such a long time, so I just came across your post. My email address has changed since I last posted, so I've been out of touch with any responses I might have received.
Anyway, I don't know how much info you may have dug up since you posted this. This is my direct line of ancestors, though. Ira Goff Trett was married to Margaret Russell in Lee County, Va. I don't have any of my information in front of me on the computer I'm using, but I have quite a lot on this family. How are you related to Ira Trett? Let me know if you still need info on these folks and I'll be happy to help.
