Klumpp Family Genealogy Forum
Here's a massive wild guess, I'm at a stand still on my husband's Klumpp line. His grandfather was Clarence Jason Klumpp, gr'grandfather Christian Klumpp, married to Amelia Rogers, and his father was Christian Klumpp married to Barbara. They are all buried in Lodi cemetery in Washtenaw Co. It's not a common name, perhaps there is a connection somewhere. Clarence's brothers were Oscar, Karl, Grover, Lester and a sister Bernice. They have all passed away too.
Let me know if I can be of help.
