Martha Rosenberg was a descendant of the Caro family, which can be traced back as far as the fifteenth century. Her ancestor Josephus Caro (1488-1575) is buried in the old Jewish cemetery in Prague. Martha Rosenberg was married to Louis Rosenberg, a government-appointed architect. They lived for many years at Güntzel Strasse 48 in Wilmersdorf. They had two daughters, Ellen (born 1891) and Käthe (whose birth date is unknown).
In 1924 Louis Rosenberg died and Martha moved in with her daughter Ellen at Limonen Strasse 11 in Steglitz. Ellen’s husband, Carl Waldeck, died the same year. Their last address in Berlin was Rosenheimer Strasse 27. On 1 September 1942, Martha Rosenberg was deported with the “54th transport of the elderly” to Theresienstadt, where she died three weeks later, on 21 September 1941. The cause of death stated on her death certificate is “enteritis”.
Martha’s daughter Ellen married her second husband, an artist named Leopold Carsch, in 1941. She was deported with him to Theresienstadt on 17 May 1944. Her husband died here after a few months. Ellen Carsch was taken to Auschwitz in May 1944.
Martha’s daughter Käthe Prein, née Rosenberg, was deported to Theresienstadt in January 1944. She survived and returned to Zehlendorf.
