School #20A
A search for 'H* Karpinski' turned up 4 results, of which only Hirsz was born in the right birth year range that would have allowed him to attend school #20A.
I matched Hirsz to his family using matching addresses. Hirsz lived with his father, Chaim (b. 1890), his mother, Ruchla (b. 1902), and his siblings Czeslawa (b. 1924) and Debora (b. 1925).
Ruchla, Czeslawa, and Debora all don't have deportation information listed with them. Chaim either moved or was deported (not clear from the note) on May 25, 1941. Hirsz was deported on September 10, 1942, on which date there was a deportation to Chelmno.
