The Denneboom sisters lived at Bamberger Str. 3 in Berlin-Wilmersdorf before emigrating back to Holland. Ida and Henriette also had a sister, Sophie Denneboom, born 12.09.1883 in Averest, who perished in Auschwitz but has no data about her deportation. If anybody knows anything about Sophie, I would appreciate the information. (Bundesarchiv Gedenkbuch, Berliner Gedenkbuch)
