Thank you for confirming that the Nebraska Duhrings are related to the Martin Duhring in my line. Martin Duehring also immigrated to Wisconsin with his sons. I believe he is buried in St. Peterii Lutheran cemetery south of Brownsville, and north of Theresa, Dodge Ct., Wisconsin. Four of my ancestor lines came from Alt Langsow, Brandenburg, Prussia: Franke, Missling, Bosin, and Duhring.
