Albert and Frieda are listed in the Breslau synagogue community address list (ca 1930) at Breslau at Hoefchenstrasse 1; their marriage certificate gives the same address for Albert. Frieda appears as the wife of Albert with the date of birth of 17/08/1873 whereas their marriage certificate gives 17/08/1893. Intriguingly, a Frida Klarenmayer (sic) born 17/08/1893 is also listed at the same address, as well as at Hohenzollenstrasse 36 which is her mother's address.
