As a matter of fact, I have found one source of information about the family of Margaret Gray. I cannot remember the website name, but I was doing a yahoo search for Abner Wheelus/ess/is and found where the decendants of the Gray family mentioned Margaret and Abner's marriage. It also gave a brief history of the Gray family. If I remember correctly, it said that the Grays were from South Carolina and Margaret's mother's maiden name was Hilton or Helton. The family later moved to Georgia. I really have a tough time following all the lines of ancestory because of the distance from where the emmigration began. But the internet really helps, when the source is legitamate. Anyway, i hope this helps. Oh, by the way, Margaret's father was William, but I cannot remember the mother's first name.
