Under a search for 'I* Apelbaum,' Icek's was the only name that came up, and his birthdate fit the years appropriate for his school.
Icek had a father, Josef/Abram (b. 1898), a mother, Estera (b. 1898), and two sisters, Frajda (b. 1927) and Mirjam (b. 1931).
Of his family, only Icek has a deportation date, September 17, 1942. There is no corresponding deportation matching that date in Secondary Sources, so as of now, Icek's fate is unknown.
