I am a descendant of Franz Fredrich Wilhelm Raduenz b. 1/25/1845 In Germany. I think that he is the brother of your Johanna Henrietta Raduenz. He came to the US in 1870; married Bertha Zahn 4/16/1874 in Cooperstown, WI. His father was Carl Raduenz(8/15/1818 - 3/23/19050. Carl came to the US in 1889 and lived with Wilhelm and his family in Montpelier, Wi.
