Marcello’s paternal grandparents were named Vincenzo Mastroianni and Concetta Conte.
Marcello’s mother was typically cited in reference books as having been born Ida Irolle.
There is a web rumor that Marcello’s mother was born Ida Idelson, to a Jewish family, in Minsk, Belarus. Genealogy website Geni.com even lists Marcello’s mother as Ida Idelson, from Belarus. It is not clear if this claim is accurate.
