No Miranda was from Naples just like Genovese. Funzi was a power well before Miranda passed away in the early 70's, he likely took over the Miranda crew when Miranda became a part of the administration put in place by Genovese. The Sicilian/Neapolitan dynamic was never an issue in that family as Luciano, who was from Sicily, had as his under boss and then acting boss Genovese, who was from Naples.
