Four-year-old Mariann lived with her family in Marczinfalva, part of Abaújszántó. During WW2, her father Bernát was called up for labour service and was killed on the Eastern Front. On 16 April 1944, Marianne, her 29-year-old mother Lotti Groszmann and her 72-year-old grandmother Matilda Kohn were taken to the school building in Abaújszántó. Within a few days they were transferred to a collection camp in a brick factory in the outskirts of Kassa. From there, they were deported to Auschwitz-Birkenau on 17 May 1944. Upon arrival, Mariann was sent to the gas chambers with her mother and grandmother.
