Gerhard von der Ahe was a close friend to my parents, i met him regularly as from my very young days until he passed away.
He was living in the city of Lübeck in North Germany, exactly in a suburb called "Kücknitz", where my parents and i lived as well. He worked from mid of the 50th until his retirement for a local newspaper called "Lübecker Nachrichten". As to my opinion he had an average midclass live. He was married to Annemie von der Ahe, they had no children, but they were very keen on dogs, which they treated like kids. I remember that he and his wife were very skilled on a German card game called "Skat", they both were club members and played on top level in the First German Skat league, as far as i know they both won a German championship, as crew and single players.
When me met he talked from time to time about his young days in the Third Reich, but honestly nobody took him very serious on this. Only later i realized that he was a legal son of Heinrich Himmler.
He peacefully died in a Nursery Home in Lübeck- Kücknitz, Solmitzstrasse, 2 years ago. His wife already died some 12/15 years ago. There are still some pictures available from him, in case of interest i can provide.
Hope this is of interest.
