From Germany to Australia 1870 - Sauer, Knoll, Duckwitz
The German line in my family came from Wollschow (near Prenzlau, NW of Berlin)and Friedberg in Germany.
Maria Christina Duckwitz 1818 - 1900 came from Wollschow.
Her son August Wilhelm Duckwitz 1841 - 1919 married 1867 to Albertine Wilhelmina Sauer 1844-1930. They migrated to Australia as part of a larger family group including Ruthenberg's in 1870.
Albertine's parents were Christian Sauer and Wilhelmina Knoll.
If you can help me go back before then I'd appreciate it.
