Dear Bill:
I sent you a separate e-mail, but are you descended from George G. JUPENA and his wife Mary MUELLER or from MICHAEL JOSEPH ("Mike") JUPENA and his wife Matilda MARIC (or MAURITZ)?
I can't find either you or your father in the two different family trees I have for the Jeanette JUPENA clans, but then I have always suspected I was missing a few people.
Mike
