Listed in the Breslau synagogue community address list (ca 1930) as Marta Epstein geb. Adler with the same date of birth as that given by JRI-Poland and living at Friedrich Wilhelmstrasse 24. The only other Epstein listed at the same address is Ruth, who I assume is her daughter. Marta and Markus had divorced by this time.

In the 1939 census Marta was living with Ruth and her assumed son at Walter at Franz-Seldte-Platz 7.

Marta was deported from Breslau to Theresienstadt concentration camp on 02/04/1943 where she died 6 months later.

Named as "Martha" in her marriage certificate and her son Walter's birth certificate, and as "Marta" in other sources.
