I have purchased a copy of church records from Berlin, Pa. There were apparently two Sweitzer brothers (Jacob and Peter). At least one of the brothers had a sone named Jacob and I think that one of the sons also named his son Jacob. It is quit confusing to me. Peter's daughter married into the Martin family, thus the tiny bit of information I have provided here. Be aware that the name was originally spelled as Schweitzer as it appeared both ways in the church records.
