We searched the name Rachel Ickowicz on exact and this was the only result. Her birth date is May 29, 1932, which puts her at an ideal age to be in school #7B. We think that she was relocated to a different flat room in the same street of Hohens. She has a transport date of June 27, 1942 on trasport 25. There were no records of any transports on this date on the secondary source, but the records before and after this date went to Auschwitz. This leaves us to believe that there is a chance she went to a labor camp and not the execution center of Chelmno.
We did an exact search of the last name Ickowicz and believe we found Rachel's father, mother, older brother, and 2 younger sisters. All four had the same ghetto addresses and were all transported on June 27, 1942. Her potentional father Jakub, mother Rywka, and brother Ljab were on transport #30 and her potention sisters Jochwet Chaja and Malka Dina was on transport 25. The father was born on August 24, 1899, the mother was born on April 20, 1898, the brother was born August 2, 1930, Jochwet sister was born on October 30, 1937, and Malka was born on May 1, 1934. This puts all of them at an ideal age to be in relation to Rachel.
