We believe Dawid Zylbersztajn was a student at a gymnasium and high school for boys located on Otylii which later changed to Ottilenstrasse when German occupating began in 1939. HIs ghetto address was Hamburger 15 37 and tthen he movied to Kilinski 46. We also believe his D-M code was 374879. Also, we have reason to believe that Benjamin Zylbersztajn was his father since he was born in 1898 and was a resident in lodz. His address was 15 Flat 37 Hamburger Strasse which is also Dawid Zylbersztajn's address.
