Caroline Mutschler was previously listed as mother for George. However, the 1860 US census and the 1865 MN census show a woman named "Louise" or "Louisa" as the probable wife and mother in the Gulden household. Additionally, Caroline Mutschler and ]]Gulden-71|Johann P. Gulden]] were not married until 1869, well after the birth of George Gulden.
