Lajbuz Blizinski born 1929 and he lived at Hanseaten 25 flat 8 and moved to Insel 35 on 16/08/1942.
I had already considerded Lejb but I thought Lajbus sounded more similar to Lajbisz... But, i think we should consider both boys.
Lejb Palasznicki born 18/05/1935 and lived at Hohens 78 flat 14. He was deported on 11/09/1942.
Lajbus's Family
I found Blima born 1901 and Jankiel born 15/02/1931 and Gitman born 1890 all living at the same address. Gitman also appears with the birthdate of 18/03/1925...
Lejb's family
I found all living at the same address Josek born 1882, Blima born 1890, Dwojra born 20/9/1919, Rachela born 1/1/1924,Leja born 22/6/1927, Mindla born 21/4/1922, and Basia born 18/10/1929. According to the seondary resources if Lejb was deported in September of 1942 then he was sent to Chelmno and killed in the gas vans. He was the only one of his family members to be deported.
