Do you know anything about another marriage of Reuben Denton, to his cousin (I think) Nancy Busby in Sumner Co. Tennessee in 1821? She is not mentioned in her father's will in 1830, so she probably died early and had no children.
William Busby, Nancy's father, married a Nancy Mitchell in Granville Co. in 1803. I think Nancy was the daughter of Major Mitchell and Molley Wiggins. I believe my John Mitchell of Sumner Co. TN who married Fanny Busby, sister of William, was the son of Major and Molley but can't prove it conclusively.
I also believe William Busby's second wife, Elizabeth, from Henderson Co. KY was a Denton, perhaps a sister to Reuben??
