Received and email from Jeaneen Terry regarding Thomas and Ann Terry of Virginia. She said she had Thomas’ will, and is related to him through his son Mills, who had a brother named Lewis. That all corresponds well to the information I have on my family of that period, however it is hard to say without seeing the specific information, since people of that time, especially in my family, tended to name their children from a limited selection of names.
I did a quick web search, and found some of the great information that Jeaneen has compiled: http://www.terry-family-historian.com/Greenbrier-FayetteCoVA/Greenbrier-FayetteCoVAMain.htm
I anxiously await her response to see what else she may have.
