I'll try to help you all I can. My maiden name is Pieper. My fathers family is Wiesbaden West Germany. The names that you mentioned Henry Pieper. I believe was my Grandfathers brother. I've heard him talked about. There was also an uncle by the name of Heinz. The Helen with the Henry is what got me to write to you. My uncle has researched the whole family tree. If I can help you further. Let me know.
