I found a Grandville Mitts in the Mitts family history book under other Mitts families that Doris could not prove were related to us at the time. This Grandville Mitts is the son of John Wesley Mitts who married a woman by the name of Mary. Had three sons, Wilburn, Byth and GrandVille Alexander Mitts b. 18 May 1875, d. 4 Jan 1943 who married Lydia MaMahan. They had ten children. Could this be the same one. If so I will send you the information I have.
The children are O.D. Clyde, Howard Wesley, Myrtle Ivie, Ollie Edward, Lola May, Claude Eugene, Vesta Velle, Alma Jean.
