Thank you so much for the information. I, too, am happy to share what I know from my grandmother's oral tradition. 

My parents and I always lived with my grandparents. As a child, I spent most of my time with my grandmother, with whom I maintained a very close relationship until the very end. My grandmother spoke with great enthusiasm about her life before the roundup, after which she was deported to Germany, and about her time there. 

She always spoke very highly of the farmer with whom she had found shelter. She also had a friendship with the farmer's daughter, Hannah, which continued even after the war. I remember that my grandmother regularly exchanged letters with her. 

We even had a personal meeting, which deeply moved us all. 

It wasn't easy to organize, as it was during the time of communist rule. But in the end, everything worked out, and it was a great joy.
