According to the family bible, and Sweet's Avery genealogy, Benjamin AVERY was born in 1768, place and parents unknown. He first appeared in Westerlo, Albany County in 1789 when he was granted a piece of land in the west Van Rensselaer manor . His first wife was Sarah Cordelia WILLIAMSON, who was born in 1768 and died in 1804. He then married Sarah DEMELT. They disappear from census and records in 1837 when they sold the land. He was the father of 19 children by the 2 wives. One son, John, was a legislator for Schoharie County. Can anyone help me find his parents?
