Tykocin returned to Soviet control in the Belostok Offensive of July 1944. Rozenszajn continued to live with the Bialowarczuks until in 1946 being reunited with her mother Bela, who had survived the Ravensbrück concentration camp and lived for a year as a refugee in Sweden. After spending several months becoming reacquainted with each other and living with the Białowarczuks, Maria and Bela Rozenszajn returned to Warsaw, but remained in contact with the Białowarczuks, who were named Righteous Among the Nations for risking their lives to save Rozenszajn.
