The Rockford, Illinois family of La Cosa Nostra has long been seen as an extension of the powerful Chicago Outfit. There is not much known about this family. There are only three known bosses. The first boss of the family was Antonio Musso, who started the family in the early thirties and was the boss until 1957. Musso's successor was Joseph Zammito. Zammito was in control of the Rockford family until 1973. In 1973, Zammito's death brought about the rule of Frank Buscemi. Buscemi is the last known boss of the Rockford family. It is not known if the family is still active, and if so, if Buscemi is still the boss.
