I thought Hawa was a likely misspelling of Chawa, so I searched for Chawa under DM Soundex and for Cyncynatus under fuzzy. There were two Chawas, but only one was the right age to have attended School #8B.
I matched Chawa to her family via matching addresses, and in one case a partial. Zefta (b. 1892), Chawa's possible mother/aunt, lived at Hanseaten 26 but in a different flat than the rest of the family. Nonetheless, I've put her down as a possible mother figure.
The siblings/cousins that lived at the exact same address as Chawa include Estera (b. 1916), Pesa (b. 1921), and Moszek (b. 1926).
Chawa was deported on September 15, 1942, although no deportation on record has that date, so as of now Chawa's fate is uncertain. Like Chawa, Zefta was also deported on a date with no deportation on record: May 27, 1942; as was Pesa, on July 26 ,1944. Estera had two notes for one date in her profile, indicating that she was either deported or moved (unclear as of now) on November 25, 1941. Moszek was deported to Chelmno on June 28, 1944.
