She married a Phillip Summers, so I assume he is the guy.
He had a son, John, who was living in Russell co., VA in 1812 and is mentioned in SV-356 page 2?
1803 Phillip Summers traded 6 acres he is living on for 7.5 acres in Augusta co., VA that Phillip Sink owns. (SV-495)
See CHALKY Vol. 2 for info about him. (SV-1570.2)
