My husband's direct lineage lists a John Rudolf Krinke born dec 26, 1874 in Faribault, MN. He died feb 13, 1962 in Ogilvie, MN and is buried in Mora, MN. I have extensive information on the Krinke lineage in MN and they have a huge family reunion every summer.I am not sure who John Rudolf was named after, but it was not his father, grandfather or great grandfather. The Krinke name, originally spelled Krienke, still has relatives in Germany. John Rudolf's father and several siblings came to the US, and other siblings stayed in Germany.
