Thank you for your interest. To the best of our knoweledge, yes, they were from Germany. My grandfather talked about his mother, Anna Marie Book being German and wearing wooden shoes around the dairy in St Louis, Missouri. Anna Marie Book was the daughter of Engelbert Book b.6/24/1839. Anna Marie married in 1903 Samuel Gutzmann (the 2nd or 3rd) . We are told the Gutzmanns are from the Alsace-Lorraine region. Samuel Gutzmann (the 1st)born 3/1814 was the first to come to America.
