Molly, this is Elaine Sledge, replying to your 2007 post on my mother's site. (I couldn't get logged in under my name, for some reason.) I accidently ran across your post, 6 years later. Haven't done a lot of research on the Edmunds in that time.
John Edmunds & Mary Watkins (?) are a "brick wall."
All I know - for sure - is that John's will was probated in June 1784 in Amherst Co., VA (WB 2, p. 181). He mentions wife Mary, children: James Edmunds, Samuel Edmunds, Elizabeth Balew, Sarah Woodrough. Moses Campbell & Ambrose Campbell were named executors.
