In The Godfather, what is the name of the Corleone family’s consigliere before Tom Hagen?

The Corleone family’s consigliere before Tom Hagen is Genco Abbandando.

Genco is Vito Corleone’s longtime friend and the original consigliere of the Corleone family. He is named after the Abbandando grocery business, where Vito worked after arriving in New York and where his relationship with Genco began.

The character appears briefly in The Godfather as a dying man visited by Vito, and the scene recalls their shared history. Genco’s role is more fully developed in the novel and in deleted or extended material associated with the film’s backstory.

Tom Hagen later succeeds him as consigliere. Genco should not be confused with Clemenza or Tessio, who are caporegimes, or Luca Brasi, who serves as Vito’s feared personal enforcer.
