Mellisa, I re-read the article and my research shows that Thomas had a son named James, but that he was born in 1793 which is too late for our James of Iredell County N.C.
However, while researching Thomas in Orange County N.C. I ran across two 11 year old orphans.One, William Chapman and the other James Abbott.(source: Orange County, North Carolina County Court Minutes 1787 thru 1793 Book IV,  - 346-folio 56 Feb Term 1788, Weynette Parks Haun }
Does Wanda Groseclose's book mention either boy and the names of their parents? Larry
