I found this information with the Lodz Ghetto Inhabitants database.
I found Chil Szaja Wajntraub living at the same first two addresses as Israel; Chil died in April of 1942. His birthdate (October 27 1895) seems right for being Israel's father. I found the matching addresses in the Lodz Ghetto List in the Lodz Ghetto Inhabitants database.
Date of move added.
