The relationship between Gerda and her parents is proposed on the basis that they all lived in Guben. A copy of Guben birth certificate 1906/465 would confirm her parents' identity.

Bernhard and Gerda are listed in the 1939 census of Berlin without any children, nor are any Chrzelitzer children listed in Yad Vashem's records of deportation from Berlin.

Bernhard and Gerda were deported from Berlin to Auschwitz concentration camp on 12/03/1943.
