Joseph and Helena lived with their son Erich in Breslau at Goethestrasse 31/33 in [BSCAL_date]. At the same address, although probably not in the same apartment, is listed Rose Nothmann geb. Bloch.

Joseph's 1932 death certificate describes him as "widowed" so Helena must have died between the compiliation of the Breslau synagogue community address list (ca 1930) and then.
