I have a Thomas Davy in my tree that was in Hardin Co, TN in the late 1800's. My mother was a Davy. Her father was Charles Tatum Davy and his father was Richard Davy married to Sarah Ellen McClain. They lived in Hardin Co and Gibson Co TN. They came into TN from the Carolina's. I can not trace them definately before that. There are tooo many Thomas Davy's. What do you have?
