3 years after you posted it I found your reference to your family marrying into the Langenbachs. My great grandfather, John Jakob Langenbach & great grandmother Emilie Louasia (Franke) Langenbach lived in Mayville from at least the 1860s to the 1880s. Prior to 1900 they all moved to San Francisco. I'm looking for any information on the family. A son, Ernst (b. 1867) m. Alma Schutte. Others got married in CA. I'm particularly interested in finding out if John Jakob Langenbach, who owned a saloon in Mayville, is related to the John Langenbach who owned a hotel in Theresa.
