Christoph,
That is an Incredibly Kind and Generous thing for your Dad to consider doing! Also, if he never has the time to get to do it, I understand.
The photos you took are splendid! I would assume from them that you are a professional photographer.
I have several things that are in my queue to send to you and hope in a few days to get to do so - one is that postmark on the letters home from Dad from the Michaelsburg Abbey and another is the photo of the door where the Morgue was.
Do you know where the wine cellar (assuming that was its original purpose) was or the place they used to hide in when the bombs came? Maybe that and the location of where the Commandant lived in the basement will be revealed in the Siegburg documents.
According to Mr. Norton they used an Outhouse for a bathroom. That had to be close by to the barracks.
It would be interesting to hear what life was like for the people of Siegburg during that time. Food had to be scarce everywhere.
Oh so much more to chat about but better go now.
Thank you again for trying to help us and so kindly sharing your knowledge!
Jean J
