Gender: boy
School:
School #6
For Moniek Nielkenbojm I only found one possible person and that was Mojsze Nelkenbaum born 10/06/1934 and he lived at Gnesen 15 flat 26. Mojsze would have been the correct Age range for school #6.
Nachman born 15/05/1903, Chawa born 12/04/1902, and Sura born 06/12/1930 were all living atthe same address. I'm guessing they were Mojsze's mother, father, and sister.
