A fuzzy search for E* Kenigsztajn turned up a few results, but only 3 were the right age to attend School #17B. Since there were only minor variations in the spelling and birthdates, as well as matching addresses, I concluded that all 3 profiles belonged to the same girl.
I looked through the database to find people with matching last names who lived at the same address (her likely family), and found her mother (Fajga, b. 1895), and brother (Joszaja, b. 1931). In addition to living at the same address, they were both deported on the same date as Estera, Sept. 9, 1942. According to Secondary Sources, there was a deportation to Chelmno on this date.
There was another date listed for Estera that I was unsure where to put. The note said 'ZAM 21.12.41', which means she registered (for something) on December 21, 1941. I looked through the labor cards and was unable to find one for her, so I'm not sure what this registration date is for.
