Hi Carol,
Thanks so much for the information! Phillip and Augusta Klumb are buried at Trinity West Mequon and a photo of the stone is on findagrave. Two of their children are on the other side of the stone. I'm unsure if Otto ever married, (he is on one side of the stone) but ancestry.com lists him as having a much younger wife and living on the Klumb farm on Donges Bay Rd so who knows.
I had difficulty finding out who Phillip and Augusta's parents were and took a stab at Jacob Klumb and Anna Conrad (Konrad) for some reason. I checked on findagrave for Friedrich Jacob Klumb and Christiane Margaret (Hoeltz) Klumb but don't find them, I hate to enter them as being interred at West Mequon or St Johns if I don't definitly know for sure so please let me know if you find out anything for sure. I have to check the findagrave site for Augusta's parents at Opitz.
I can remember seeing St John's Church on Donges Bay Rd so many times....... never knowing that my great great-grandparents were buried there!
