Thanks. Since my query, I have confirmed Andrew Jackson to within 99 percent certainty as well.
Additionally, it is also possible that Thomas Benton VW (the spouse of Eliz. Smart) is also a brother to our David Lawson VW, although he is not connected in the genealogy book. Although T.B. was much older (by about 15 years), I spoke with one of his descendants - Melanie Hester - who said that he was born in So. Carolina (like DL) and, like DL, his parents were Jesse VW and Mary Ann Braeden. Has she been in touch with you, jcvw?
