On August 23, 1942, a group of eight Dutch Jews tried to enter Switzerland through the Jura mountains, in the Risoux massif. When arrested, two of them (Abraham de Vries and Nathan Israel) attempted suicide, and were sent to hospital; they could stay in Switzerland with their wives. The four others, a family from the Hague, were turned back: Naatje Huisman née Bobbe (born 4.6.1879), wife of Joseph Huisman; her unmarried daughter Roosje (born 1.6.1908); her other daughter Jerie Elburg née Huisman (born 15.4.1912), with her husband, Salomon Elburg (born 18.4.1913).
