I was nosing around the internet, sort of working on Nuber genealogy when I saw your messages. Christian Nuber was also my great great grandfather. I am descended from his son Albert C., who was William's younger brother. Albert was my great grandfather, Albert's son Frank was my grandfather, Frank's son Robert was my father. I would be happy to share any information I have, and to learn of yours.
Best to contact me by e-mail.
