Brian, I have very little information on Johann's family--I know he had a sister, but I don't know her name. His parents were Wilhelm Schaller and Margareta Tiefel Schaller. Johann's birthdate is October 26, 1898. Does this match anything you have? Like I said in my original post, my mom is an only child and he died when she was very young. I think the family was small, but she knew of one relative who came over here in the late 20's or so.
