I am searching for any information on Sophia Karnau born 23 March 1809 in Thedinghausen. She immigrated to the United States in 1844 at the same time as Johann Dietrich Bergmann from Schwarme whom she would later marry. They are my great-great grandparents and I have been unable to find anything on their families in Germany. I would appreciate any information or suggestions of where to search other than Ancestry, google, and familysearch.com. Thank you.
