In March 1944, Italian sisters Tati (six) and Andra (four) were taken to Auschwitz, to the Kinder Block presided over by Josef Mengele. Only 70 children survived the camp. Throughout it all they clung to their promise to their mother to 'always remember your name'. It was this that brought them back to their parents, years later. The sisters lived long lives, bearing witness as survivors of the Holocaust.
