Henry SCHULTHEIS and Albine ZAPF had 3 children, Henry, Julius and Marie (Mitzi). Mitzi married Earl Stauffer HARTMAN and they had two children, Gertrude (Trudy) and Louis. Louis married Blanche GELDERS, my grandmother.
I'm not sure any of that will help, but that's what I have.
I also know that Henry Sr. was born around 1864/5 in Germany. I believe he had siblings or other relatives in New York, but I don't know their names. Perhaps my grandfather does. I'll ask.
