The family members that I was able to find for Menachem were found by searching last name, matching addresses, and paying attention to birth dates. Hersz I believe is his father because of his birth year (1888). Rajzla is the oldest female listed at the address (1885), which led me to believe that she was his mother. His siblings are all generally older than him. Chaja (1912), Chaim (1914), Chana (1918), Lajb (1920), Hinda (1926), and Szlama. I was also able to find a deportation date listed of 10.9.42, and after looking at secondary resources, I was able to determine that his transport arrived at Chelmno during a mass round-up. I was able to find this information by searching jewishge.org (the Lodz Ghetto Inhabitants database). On the USHHM database, the date of 10.9 was given but the year was absent. On jewishgen.org the date 10.9.42 was given. I also located his family by matching addresses through the spreadsheet style database at jewishgen (even though it is the same as USHHM), and then cross-referenced the material at the administrative database listed for the project.
