My great-grandfater was Otto August Kurth, and my great-great-grandfather was Frederich Edward (Edouard?) Kurth, who was married to Bertha Louisa Wagner. My information says he was 14 when he came to America with his parents, Gottlieb(Gottlob) Kurth and Tresase Doberenz Kurth, in 1868. They apparently settled in Illinois before moving to Kansas. Betha's parents were Frederich Wagner and Louise Schroder Wagner, who also immigrated from Germany. I hope this helps, and I would appreciate any additional information about the names of the earlier German ancestors, or any specific birth or death dates of Gottlob, Tresase, or Edouard.
