I am tammy, great great granddaughter of Johann. he can be found listed in St.dominic's church records under John Blumenstein. The church is found at Breese, Illinois. baptismal and cemetery records are found online. I don't know how much this helps, but it appears he had an alternate name.
My line: Johann (John), Reinhold, Stanley, Karen. i just syumbled across you in a curiosity search, felt a need to reply. Good Luck!
