I was intrigued by a post that you receved some years back where there is a reference to Frank Witthuhn being born in Netzow. If it was Netzow near Templin then my great-great grandfather (whose name was Johannes Heinlein) was the school teacher in this town. I have visited this tiny village. At the time of Frank's birth there were about 150 people in the village and my family had 11 children.
I have a poorly translated copy of a diary written by my great-great grandfather.
