Family legend states that the first Sylvester was a French Huguenot who settled in Wales using the surname Dupaty. He immigrated to America and it was here that the name was changed to Deputy. Sylvester Sr. died before 01 Apr 1761. My problem is that I have never been able to place this name in Wales. There are numerous references to the name Dupaty on the web but they are in the French language and my high school French has long since been forgotten. Can any one help with this name?
