I found two boys that fit for Jakub Baljanski born between the years of 1926 and 1931.
1.) the first boy I found was Jakob Polanski born 7/06/1929 and he lived at Fisch 30 flat 10 and he was deported on 20/03/1942 to Chelmno.
2.) The second boy was Jakub Polanski born 17/12/1929 and he lived at Brunnen 7, Insel 18 flat 2, and he moved on 30/06/1944 to Franz 26.
I couldn't find anymore information on Jakob Polanski.
I found Jakub's family and they are Kalma Mojsze Polanski born 1902, Chaja Pesa Polanska nee Kaminska born 1904 and she died in the Lodz Ghetto on 22/10/1943, and his sister Rachela Polanska born 14/05/1938.
