According to the search of the literal name there were no results, but using the sounds like option four came up. Mordek Herszberg, seems to fit the description of this boy the best. He was born in 1929 right in the range of the students at School 2, He also has his occupation as student. Based on the similarity of the name and the other indicators I belive this to be the student.
According to the sources, it states the Morecka was transported to Chelmnol, as were most of his family. I went through and searched for his address and was able to find the Father Szmul who was born in 1894, which I think would make hime about the right age. His wife was Laja and for occupation she had housewife, she was born in 1896. I assumed that these date seemed to lead to the parents of Mordeka. I was also able to find 2 sisters and a brother to him, Is there somewhere where I can put that, Their names are ZLATA HERSZBERG, GOLDA HERSZBERG, and ABRAM MENDEL HERSZBERG. By the way what does the occupation of angest consist of, I could find no information on it.
