Found 3 possible people that match up with the name, did fuzzy/DM searches and came up with Chaim Moszek Orbach, Mojzesz Aron Orbach and Mosche Orbach, all born in 1929 which matches up with the age this boy would be at school 13B. Multiple potential addresses for the 3 possible identities. With the last possible identity Mosche Orbach, found a potential death at Auschwitz and parent identities Izchak and Chana
