Hi, everyone. I am Harris (Harry) Heartwell's GGDaughter. His father was Oscar Fitzallen Heartwell, son of Oscar Fitzallen Hartwell. Does anybody know these names or why the name was changed? We heard that there were three or four brothers, and our ancestor had a falling out with the others before heading west.Harry was married to Cora Belle Sponsler. I have just started this search, so any help is greatly appreciated!
