I agree, Luciano Fannuci - It is unrealistic for every Boss of the Corleone Family in the Family's history to be called Corleone. The five Families in New York in real life don't only allow Genoveses, Gambinos, Bonannos, Colombos or Lucheses to become Bosses of their Families, so I would like to see a Boss of the Corleone Family who is not called Corleone, in The Godfather Part IV, if it is ever created.
