With Hitler's rise to power and the invasion of Czechoslovakia by the Third Reich, Sojka's non-practicing Jewish family was threatened. In 1938, Sojka married Dezider Schwartz, a Slovak civil servant. They moved to live in Nitra, Slovakia, at Priehradná 6 street. In 1942, the couple was aplarently transported to Majdanek concentration camp. This information remains unclear. Perhaps they managed to escape or hid, because in 1944 they were living in the same place, in Nitra. After the National Uprising, they werd sent first to Sered' labour camp, then, in October 1944, to Auschwitz Concentration Camp.
