I recently found a Henry Presher in Westchester County, NY History. He is listed in Westchester, Westchester County, NY during the Revolutionary War. Also found in the 1790 Census for Cortlandt, Westchester County, NY Abraham and William. I believe this is my William Presher who married Anna Wright. I just recently found their son in the Old Van Cortlandt Cemetery, Wright Presher, who died at one year old. John Presher who is William's son also ended up in Nichols, Tioga County, NY for a short time and then went on to Wisconsin. Somehow I think this family is tied together.
Maybe this will give you a little help. My Eunice Presher below is William and Anna's granddaughter.
