Yad Vashem Archives, Jerusalem — the card file of Jewish refugees from Poland who found refuge in various countries, 1939–1941 Yad Vashem's card file of Jewish refugees from Poland who found refuge in various countries, 1939–1941, has a card for Josef Kamieniecki, born in 1893, a factory owner of Warsaw, who was in Wilno during the war, and beside it a card for his son Viktor, born in 1923, which names his father Josef. The year and the son agree with this register line; the register's other Josef Kamieniecki was some fourteen years younger. Credit: Yad Vashem Archives.
