Michael (Mikel as it is on tombstone) Lau is my 5th Great Grandfather. He married Maria Elizabetha Bortner but we are all confused as to when she was born as she is suppose to be Balthaser's daughter. She would have been born in 1732 and Michael Sr. was not born until 1771. Michael's father was Philip Lau, son of Christian Lau from Germany. Christian and Conrad came to Pennsylvania on the ship "John and William" in 1732. Pink is explaining the type of ship is is. It is really not the title of the ship but the make of the ship. Christian father was Hans Theobald Lau from Germany. This is my lineage. I would be glad to help you if I can.
