I am also researching a Bauch family. Willam Bauch, who lived in Wisrick, Posen, had at least 4 children, three of whom came to Wisconsin in the 1870's and settled near Augusta, WI. The three that came over were: John Friedrich Bauch, from whom I am descended, Edward Freiderich Bauch, and Pauline Bauch, who married Ludwig Steinke.
