In July 1941, an obituary was placed in Het Joodsche Weekblad for B. de Pool-Roos.

These and any subsequent obituaries provide insufficient information to identify the family of the deceased. This could mean that this person or these persons appear again elsewhere in the Monument: by name or as a possible survivor without personal data. If you know which family the deceased belonged to, we would be very grateful if you let us know.
