Izak Lieberman, who attended School #1 and was most likely born between 1926 and 1932. We think, based on all the results and dates, that Icek Liberman born in 1926 is our student. He lived at Franz 56 54 and Ost 63.
In looking at the possibility of Icchok Liberman, we don't think that's the one because of the shape of the name. Our orginal prompt was Izak, and Icek seems much closer when written. Is that logical for us to think?
We looked through a list of 516 names for similar addresses to find family members. Szejwa Liberman was born in 1928, and lived in the same two addresses. We believe she was a sister. Hena Liberman was born in 1924 and lived at the same addresses, and was most likely an older sister. Hilel Liberman has the same addresses and was born in 1902 so we think he’s probably the father.
