I have him documented from 1753 to his death in Surry Co., NC in 1806. He was married to Mary StClair (Sinclair/Sinkler) whose father was documented coming from Glaskow, Scotland with 4 years indentured service. I have mostly documented his descendants (9 children) and their descendants.
There was a Richard (father) and Edward (son) Wilbourn in records in Spotsylvania Co., VA in 1747, but not enough to link to the Prince William records. My 37 marker DNA is a match to 3 or 4 lines of Wilburns/Wilbourns/etc. all originating in central VA, but is not a match to the Baltimore nor Accomack Wilbourns.
