Hello, I am searching for information on the Winterfeld and Groff families. Johann Wilhelm Ludwig Winterfeld was born June 18, 1793 in Grabow and died 1849 in Germany. I believe his parents are Ludwig Winterfeld and Maria Elisabeth Wesel. He married Anna Marie Groff born May 22, 1797 and died 1867 in Le Mars, Iowa, United States. If anyone could please help me, I would be so happy. Thank you. Jan Rachuy
