I know this is a rather old thread, but if it helps, I believe your John Henry Crone to be my g-g grandfather, through his daughter, Virgina E. Crone (your "Emmi" or "Emmily").B 22 Oct 1896, D 5 Jan 1978
I have her siblings as Lizzie, George, Jeff (possibly Thomas Jeff?), and Umphrey.Her mother, I have as Harriet Ford, daughter of George Washington Ford and Permilia Langston.
I have hit a wall with John Henry.Family lore says he died when Virginia was 3 (1899?).There is a land grant recordin Wood County, TX in 1897, and in the 1900 census, Hariett Ford is listed as "widowed."
Again, I know it might be old news.I was excited, though, to find your thread.
