Hello,
I just saw your posting.
I was born in Ellwangen,1948, apparently in the DP camp hospital.
My parents were Ukrainian and met there and got married.
I don't have a lot of info to share, I visited there twice on vacations. Nothing is left of the camp that I could find.
I too am researching and have just started my quest.
If you care to chat and share, I would be happy to.
Wasyl
