Bernard (also known as Bob) and Frits Verduin went into hiding, possibly at the psychiatric institution Apeldoornse Bos. They were arrested. Bernard was deported to Buchenwald, where he died shortly after the evacuation of the so called 'Kleine Lager'. The father and stepmother of the two brothers survived the war.
Addition of a visitor of the website
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.
A Liro card remains for this person or family. The cards are now at the Nationaal Archief.
