Thanks for your reply Jennifer.
I spent some time in Germany/Poland last year doing some more research (more on the male side of the family)
This info was about the female side. After meeting up with family in Germany and reading and researching more, I do now think that the camp they were in was in or near Munich. Only because getting from Berlin to near Stuttgart seems to be a long journey in those days.
I have since learnt the factory they worked at helped them alot. They kept the families together during the time they were at the camp. When they were released, they were given papers to help them along.
I hope to get back there some day to do more and visit Stuttgart (time jsut didnt permit on this visit)
