I am helping a friend whose mother was Adelheid Wucherpfennig born abt 1925. She emigrated from Germany after WWII and married but died young leaving my friend and his three siblings orphans. I have found her airline passage to the US but nothing else. He thought her father was burgermeister for Cologne Germany but doesn't know for sure. Could this be a relation to your Wucherpfennigs? He thought his grandmother's maiden name was Ruhman or Rohman.
Thanks--it means a lot to him and I really want to give this my best effort.
