After the Soviet invasion of Poland on September 19, 1939 and the subsequent occupation of Lwów, Mark Gottesman was accused of counter-revolutionary activities and was arrested by the NKVD; nothing is known about him after this point. In 1941, under the German occupation of Lwów, Łucja Frey was resettled to the ghetto and forced to work in Ghettopoliklinik in Zamarstynowska 112. She was probably murdered together with her patients during liquidation of the ghetto in August 1942 or shortly after deportation to Belzec extermination camp. No evidence exists, that she, or any of her relatives, survived.
