I recently came across a family Bible for one of my family's ancestors John Fritz (b. 17 Feb 1796) and Susannah Barger (b. 12 Jun 1800). They married in West Buffalo, PA at a Lutheran Church on 06 Dec 1818, but I've hit a wall. They later also lived in Rush, Monroe County, NY. However, I can't find marriage records or birth records from that time period for them. Anyone have any idea where I can find who their parents are? Their death records list them as "unknown" (they died in Michigan).
