Gender: boy
School:
School #1
The other possibility in the database was a boy by the name of Mordechaj Poznanski who was listed as deported.
AUSG MARZ 42 TR 36
So in reality, this person could very well be the one I am searching for.
I tried to search the addresses to see who would have been in closer proximity to school #1 by using their street addresses in the ghetto, but could not find the school's location or their living locations on any maps.
