I don't know if this will help, but it looks to me like there may be a connection. My Ggrandma's name was
Mina Weigel. She was the daughter of William (
Wilhelm)
Weigel and Maria
Hahne. Maria was born in
Wimmer,
Hanover, Germany, May 19, 1844. She is the daughter of F. Hahne (Frederick?) and Elsabein Wulfman. She had at least one brother, Henry. She came to
America at age 11--so about 1855. The
Hahne that live in and around Nashville, IL are of the same family. I'm just starting to research so this is all I have. Hope it helps. Feel free to email me directly.
