I've found, in the Tennessee census, that David and Mary are in Jefferson County, TN in 1830.Mary has 2 sons between 15 and 20 years old (William and John Moses).She has one daughter between 20 and 30 (must be Winnie, b. 28 Dec 1806 in Charlotte Co, VA because Elizabeth married in 1819 in NC).Mary is 70-80 years old.John must have died before 1830.David and his wife are 30-40 and have 2 sons <5, 1 is 5-10, 1 is 10-15, and 1 daughter <5, 2 are 5-10 and 1 is 10-15.
