The township's name reminds of the
German city
Osnabrück - the
German part
-brück ("bridge") was changed to
-burg ("castle"), to avoid the letter "ü". It is the only Osnaburg Township statewide. In 1833, Osnaburg Township contained one
gristmill, seven saw mills, two
tanneries, four stores, and one German and English book office. ==Government==
