School #6
For Chaja Cykiert I found Chaja Jedyta Cykiert born 1929 and living at Insel 7 and Insel 7 Flat 9A. She would have been the right age to attend School #6.
I found Malka born 1899 and deported on 21/03/1942, Majer Wolf born 1937, and Josef born 1927, and Herz Noach born 1925 all living at the same address as Chaja. I'm guessing they are her brothers and mother and they were all deported on the same day except for Malka and Herz.
