Everyone that has been posting that Billy D'Elia was/is the last remaining member of the Bufalino crime family is one hundred percent correct. The Scranton family has one known member in D'Elia (although I would say there is a chance that D'Elia maybe made one or two guys without the FBI knowing, thirty guys is way far fetched).

Many families are extinct (Denver, Dallas, Rochester, San Francisco, San Diego), near extinct (New Orleans, Pittsburgh, Los Angeles, Tampa), on their last legs (Buffalo), medium sized (New Jersey, Philadelphia, New England) or are one of the large and powerful families (Outfit, Partnership, the five families).
