I'm new'ish to genealogy but my calculation is that you would be my 5th cousin X times removed. I am the 9th generation of Wallick's in the US.
My parents left Van Wert before I was born in 1967. We all currently live in SC.They are in Aiken and we're in Columbia.We go back to Van Wert about once a year to visit relatives but I am not aware of any Rainsbergers.Of course that is not saying much I/we have not searched out associated relatives.
I would imagine you have John's prior generations back to Hans Michael Wallick but if not I have this information.
I would be interested in more of the Rainsberger genealogy information.
