A Sicilian immigrant and midwife in Little Italy in the 1930s, Filomena's husband was a friend of Vito Corleone. Her life was changed irreparably when Luca Brasi came to her one night to have her deliver his child, which he had fathered with an Irish girl Kelly O'Rourke, before forcing her to throw the newborn into the furnace. Traumatized, Filomena went to Don Corleone for protection and was sent back to Sicily work for his friend Don Tommasino in Sicily.
When Michael Corleone was hiding out in Sicily, he had Filomena tell him the story, which both his father and Tom Hagen had withheld from him. Filomena expressed her desire to see Brasi burn in Hell for his atrocities.
