Welcome to Afrigeneas -- this is a good place to start.

First you probably want to post yoor query on the surname board, which is more geared to current family research rather than the 1800's.

Second, what do you know? Do you know the names of either sets of parents? That would help anyone trying to help you. Were they lifetime Ohio residents, or did they move in from somewhere else?

Have you already obtained death certificates? For them or their parents? That would be a good place to start documenting their life. Genealogists all worry about documentation or a "paper trail" something to verify their facts.

Have you located them in any census records yet? What records does your library have available?
