The historical 'Rock Methodist Episcopal Church' is currently known as the Old Rocks Church. Located at 260 MOUNT AIRY--HARBOURTON RD., LAMBERTVILLE NJ 08530, the Rev Dave Errickson is the pastor and would probably be the best starting place to locate church records. You might want to write to the church at the above address, or call the church number (609) 397-2588. Hope this helps, Helen
