You have the same surnames as I do: Berger, Lange, Eiden, and from Jefferson, WI. But I do not have an Anna. My Eiden is Clotilda, not sure what her husband's name was off hand. She and her family stayed in the Jefferson area. Some of her brothers (Berger) moved away from there. A couple went to Chicago and one eventually went to McHenry County, Illinois.
I am wondering if Anna's husband and Tillie's husband might be brothers or at least related.
Lange - My Lange's family came from Rosin, Wisconsin. Minnie Lange married Wilhelm Hacker in Elgin, Illinois. W. Hacker was from McHenry, McHenry County, Illinois. Doesn't sound like our Lange families are connected. But you never know.
Let me know if you have any questions or think we may be connected somewhere.
