Jennifer, I am your grandfather's second cousin and grewup just a few blocks from him. I met your Grandmother, Penny and your father at Ft. Benning, Ga. in 1963. As you may know, your grandfather, Orleans did quite a bit of genealogical research on the Jambon family. I've done a bt too going back 7 generations to France.
If you know where your grandmother Penny can be located, a former neighbor of hers at Ft. Benning is trying to locate her. I'd appreciate a reply. Bye
