John W. Harvey was the son of Isham (Sim) Harvey (b. bet. 1790 and 1810; d. aft. 1810 Franklin Co., TN) and Elizabeth (Betty) Fore. Other possible children besides Sarah who married the Overton are Robert Harvey, P. Holcomb Harvey, H. Isham Harvey. John's middle initial most probably stands for Walton. There are a large number of John Walton Harvey's in Charlotte Co. who are all descendants of Isham "Sim" Harvey's parents, William M. Harvey, SM (SM...for Saw Mill as he was the William Harvey that ran the saw mill) and Agnes Walton, dau. of the Rev. Simeon Walton Harvey, Sr. and Agnes Hester. I descend from William M. Harvey, SM through his son John Walton Harvey who married Susannah Leonard Ford. By the way, a number of people with the surname "Fore" changed it to "Ford" so look for that when researching. Susannah Ford was the granddaughter of a Fore.
