I am trying to trace my partners' mothers family, without a lot of success.

Her maiden name is SIWEK, having been born in Buchenwald Germany in 1946, shortly after it's liberation. Her father Janis was a translator. He was married once and had three children and then remarried to a CZECHOWICZ, both having been born in Poland. They came to Australia after the war.

Jan Leon's father's name was Stephen, but I cannot find anything more about them. If anyone can help me with Polish research, I would be very grateful. Thank you.
