I believe that Joseph and Anna's sons Frank (Francis Joseph), and William married two Fellenz sisters, Theresa and Anna, respectively.See also http://bdjd.faithweb.com/fellenz.htmlhttp://bdjd.faithweb.com/fellenz.html.Francis and Theresa's son Ambrose is my grandfather.Oral family tradition says that your Joseph was from Hamburg, Germany where he was born in 1829. Also, his wife's name was Mary(?). She was born in 1833 also in Hamburg and died in 1910, but I don't know where.Also oral tradition says that Francis was born in Rochester, NY and that the family moved to Theresa, WI where I have found record of other Wilhelms in the vicinity earlier that I have to believe are also relatives that immigrated sooner (coincidence?).See the Wisconsin Volunteers, War of the Rebellion 1861-1865 Roll for Jacob, Jr. Wilhelm (1st Calvary, D Co.) and Peter Wilhelm (21st Infantry, Unassigned).Theresa Fellenz Wilhelm died in Cadott in 1926, (another coincidence?)If you find out more about Joseph and Anna/Mary, I would appreciate knowing.
