Thank you so much for your reply and information regarding the Rauch-mill. Katharina "Katie" Herberth, whose mother was a Rauch, traveled from the US to visit relatives in Germany, Bavaria and Austria in 1923. Katie was born in Wiesenfeld, Karlstadt, Bavaria in 1873. Her parents, John and Katharina (Rauch) Herberth, married in Wiesenfeld in 1849. This is the earliest date with a corresponding location that I can find on the family. Again, thank you so much. Every clue helps, as I've been researching this family since 1973.
