I haven't a clue about the family name although I've been able to do some basic research on the graveyard itself. It was originally the Bethel Lutheran Church cemetery, the church being founded in 1826 by Adam Culp, a son of Baltzer Culp, a German immigrant who fought in the Revolution. The church building is no longer exists and the cemetery itself is tucked away on a wooded hillside - interestingly, it is maintained and the grass had recently been cut when I visited the other day. There are several Culp graves as well as others belonging to members of the congregation. Now that I have a bit of background knowledge I'll be able to recognize those graves on the next visit.
