My great-great grandfather was Frederick Doerr, born 4 Jun 1831 in Germany (probably Hesse Cassel. He died 5 Jul 1888, probably in Marquette, Michigan. He was married to Susan Emmert, we think from Wirtenberg, Germany. She was born 17 Aug 1835, and died in Marquette, Michigan 20 Oct 1887, or thereabouts. They had following children:
Henry - born 11 Feb 1854; Sophie (Sophia)- born 1858(?); Elizabeth (Lizzie) - born 4 Jan 1860; Mary Ann - born 31 May 1862; William Andrew - born 6 Jul 1864; Rosy - born 16 Jul 1869, Rosa - born Oct 1870; and Carrie (Caroline) - born 16 Mar 1873. There may be others I'm not aware of. If anyone has any information on any of these family members, but especially the parents, please contact me. William Andrew is my direct line ancestor.
