At the time of the 1939 census Johanna was listed under her maiden name in Berlin-Wilmersdorf at Mommsenstrasse 55, a so-called "forced home" where Jews were compulsorily housed; no other obvious family members are listed at this address.

Johanna emigrated to England on 21.08.1939. She and her sister Jenny have the same address on the enemy alien records.

Her death is registered under her maiden name; I assume she never married.
