School #20B
Although multiple results came up for A* Borzykowski, only Abram (the two profiles of Abram had two variations of the same middle name and were born in the same year, so I presumed them to be the same person) was born in the right birthrange to have attended School #20B.
I found Abram's family by matching addresses. Abram lived with his father, Jakub (b. 1884), and siblings Mendel (b. 1916) and Szlama (b. 1914).
While there is no deportation information listed for Szlama, identical deportation dates were given for Abram, Jakub, and Mendel. However, Abram was on transport 26 while Jakub and Mendel were on transport 30. They were all deported on March 10, 1942, during the month of daily deportations to Chelmno.
