“Two thousand five hundred. According to the documents Yoel has studied, that was the number of Jewish children hidden by Christian families during the war. Two thousand five hundred Jewish children, most of them from Amsterdam. According to Dutch law only those children with a surviving parent were eventually returned, while according to reality only those children whose surviving parent managed to find where they had been hidden were returned. Many children therefore remained with the families that had hidden them. Many of the hidden children were complete unaware that they were not the biological offspring of the people who raised them, Many are unaware of it to this days.”
