If this information is correct then Isaac Gibson who died in 1790 at Onslow County, North Carolina is the son of William Gibson and not Jacob Gibson of Prince William County, Virginia as many have shown on the usual genealogy message boards.There is no evidence that Jacob Gibson's son Isaac went to Onslow County, North Carolina.
