I don't know if this is at all helpfull, but I am a descendant of Martha Huson, who had a twin sister mary-she became a doctor and practiced in NYC. My great grandmother married Merman Keep. The family is all from that area of NY, but we can't find any of Martha and Mary's many siblings. We do know the father moved the family north at the time of the civil war, from Washinton, DC. Your mention of Cayuga means lots as this is the only referance I've had yet about a Huson around the finger lake area. Do you have anything else? Thanks!
