I also have an Edgar Simonds of upstate NY. He probably isn't yours, as he was born in 1837. My Edgar is a brother to my great grandmother, Lydia Simonds, born in 1848 and their father is Jennings Simonds, born 1801 in NY. Judging by the gap in the children's ages, Lydia is from a second marriage. I never find Jennings, or either of the other kids, Edgar or brother Francis, b. 1839 on any other census. In 1850, they are in Oswego Co., in the town of Constantia.
