OK, I had to call my brother on the road to ask if he remembered the address. It was Martha Getrost , Lampertheim Heide. He couldn't remember the # and he said it was a rural part of Lampertheim so something like a Rural Route. He was stationed at Coleman AFB (he was an Army guy, so not sure why at an AFB)and lived off base.
My brothers rental house is in Rio Vista which is where he lived when he was in the Air Force. Huh, I thought you said he was in the Army. Yep, enlisted Army got out in the real world for college, didn't like it , so he reenlisted Air Force.

I'll have to ask my Mom if she knew her. I had to look up where Rio Vista is..I see it's up by San Francisco, where one of my son's live. I'm sure your brother has has many interesting stories to tell! Thanks for sharing :)
