A few letters and postcards remain that Abraham Beem (whose name in hiding was Bram) and Eva Beem (whose name in hiding was Lini) sent their parents in hiding from their address in hiding. A Sinterklaas rhyme in the autograph album of Eva Beem (dated 5 December 1942), a geography examination and two postcards, sent from Westerbork on 21 May 1943, remain as well.

The parents and children of the family Beem were in hiding in separate places. Eva and her brother were sent to a christian family in Ermelo. She was given a new identity and name: Linni de Witt. This was the reason why she could go to school. The children Eva and Abraham Beem were captured in their hiding place and deported in February 1944. They were caught probably with help of Dutch collaborators who could earn money by turning in Jews in hiding.
