I couldn't find any results for Benjamin Grass but I did find two boys named Benjamin GROSS.
The frist Benjamin was born in 1928 and he lived at REIGER 13 flat 11 and POLUDNIO 38. The second Benjamin I found was born on 30 July 1928 and he lived at Sattler 24 flat 4.
Both boys were born between the correct years 1926 and 1932.
Benjamin Gross (Reiger address) died in the Lodz ghetto on 20 July 1942 from Lungentuberkulose and it says he was born in Zd.-Wola and I believe this is Zduńska Wola, Poland. I found his father as Berek Gross born 1902 and died on day after his son on 21 July 1942. His mother was Marjem born 1900, and his siblings/cousins were Moszek born 1928 (possibly his cousin due to the same birth years) and Symcha born 1929.
For Benjamin Gross (Sattler address) I found a number of people living at his address. I believe his father was Mojsze born 14/12/1902, his mother was Hinda born 10/03/1902, his siblings as Szlama born 24/04/1924, Zosia born 30/10/1929, Zlata born 05/12/1932, Szmul born 10/12/1934, Jossek born 15/12/1936, and Natan born 20/10/1939. I looked through the other stages and didnt find anymore on Benjamin or his family.
