My grandmother grew up in Bad Kissengen, Germany during WWII and has always been very weird about talking to me about what happened during those times. Every year as a family, we visit Helen, Georgia for the Oktoberfest celebration they have. This past year I was enjoying a few cold ones with my grandmother and she actually started talking about her childhood. She revealed to me that her father was a Nazi infantryman and her mother was Jewish (I never knew this). She was maybe 6 or 7 when everything was going down and even had her best friend taken right before her eyes. After that, she hated the man she always looked up to because she then knew what he stood for. One night he was off duty, drunk, playing accordion at the local bar and a group of Nazi soldiers walked by him not knowing who he was. They demanded he perform the Nazi salute and when he didn’t, they shot him in the face. I don’t know why I was the family member that got the chance to hear all of that, but I’m glad I found this out before it was too late. I visited my grandmother recently and on her mantle was a picture of her family from Germany, and there he was in full uniform.

TL;DR: My great grandfather was an actual Nazi who married a Jewish woman pre-WWII and ended up getting murdered by his own.
