Maternal Grandfather's line:
BEISMER Family - Casparus Besemere married to Sarah Van Vliet - However, I haven't connected our immediate family with this couple. Casparus and Sarah were in Rochester, Monroe Co., NY. The best connected, furthest back ancestors are: Cornelius Beesimer married to Maria Catharine Vandermark living in Debruce. There is a Cornelius Beesimer living in Rochester, Ulster Co. but I have not yet verified that they are the same person. The surname has been a problem. As you can see there are three variation in this paragraph; I have about two dozen variants.
VANDE(R)MARK Family - Simeon Vandemark married to Mary Jane Hogancamp. Simeon's parents may have been John Vandemark and Janneke Ennest but I haven't verified that yet.
