I think that your Mary Carnahan is the same as mine. David, however, was her son, not her husband. David was born on March 13th, 1821. Mary was born Jan. 3, 1795. These dates come from the Family Bible entry supplied so generously by Jody Thomson. As far as the names of her parents are concerned, I have only the notes of A.J.Adair, who was married to Mary's Grandaughter, Oda Youree. His source was most likely Oda's mother, Frances Wallen Youree, widow of Jesse Russell Youree. Tried to email you but it came back . Would love to exchange pictures.
