My granddfather, father was Andrew St. Amand, and goes back to Louis Andre dit t.Amand> By Andrew was born approx. 1802/3 and married to Jane Lennon. They had a son Abdrew, as well as several other children. Several of the children moved to the Oswego New York area. Let me know if any of thias connects to you. I can pull out more detailed information, but it could be a possible connection. Thanks
