We have been unable to determine whether one or more members of this family survived the war. While their names do not appear on the lists of survivors, we have not been able to trace them in In Memoriam either. They are therefore labeled as 'surviving' and their names are not listed.
In addition, a Jokos file (number 30918) on this family is at the Amsterdam Municipal Archive. Access is subject to authorization from the Stichting Joods Maatschappelijk Werk.
