At the beginning the Outfit was formed with the unification of a dozen Italian and non-Italian gangs or mobs and one of them was the Sicilian Mafia. Since they had more than one conflict with the Caponites, still the whole situation was stabilized forever when Ross Prio became the boss of the so-called semi-Sicilian faction or whats left of them aka the North Side Mob.

In addition, besides not being official CN members, still during the old days some non-Italians had the same stature in the Outfit as the ones who were made within the national CN organization
