I have recently discovered a letter written from Stone's River, TN, in 1853 by the Uncle of Ann Vanderville--one Samuel Steele...only he calls John, "John Vanderver."The letter was written to the father of Ann, Samuel's brother.Samuel also mentions Susan Steele, who married Thomas Fuqua.
He relates to his brother that Vandever died, and Ann(a) married W.O. Carter, widower, former son-in-law of "old John Blair."This all checks out. Samuel refers to Ann as Anna.
