Lane, my gr-grandfather Carlos Emery Hait was born in Clyde, Wayne Cty, NY, 16 Oct 1828. Carlos parents died and he was raised by his aunt Mabel (Strong) Griffing. Carlos had a brother, William, born in 1824 and a younger sister, Hepsey Ann, born on 12 Jan 1831 both born in New York. Do you know anything about your grandfather's parents? They might be cousins of my gr-grandfather.
What town and county was your grandfather born? Have you looked in the 1880 or 1900 census to find his parents and siblings?
