Your message contains some news to me and so I hope that we will eventually manage to find some of their descendents. I did not know anything about son Joseph so far. Mary on the other hand is not shown on the census. She might be born after 1900.
You mentioned that there is additional information in the local papers archives. I would appreciate any kind of information that could get me a step closer to finding living descendents.
If you have any German background, do not hesitate to contact me, I might be able to do some translation for you or provide you with information on locations or history.
