Wow! I guess it was a family affair, after all! :-)
According to a list of cemeteries in St. Louis, Bellefontaine Cemetery, not to be confused with Bellefontaine Methodist Cemetery, formerly known as Old Bissell Cemetery.
How interesting that some of the children would stay in PA while the older generation would move to MO. I guess a road trip is in order, since St. Louis is only a few hours away!
Thank you!
