The Crime Family has a history of criminal activity dating back to the late nineteenth century.  The family reached its height of influence under Carlos Marcello, one of America's most powerful Mafia dons during the mid-twentieth century and at its height had over a hundred members.  However, a series of setbacks during the 1980s reduced its clout, and law enforcement dismantled most of what remained shortly after Marcello's death in 1993.  In spite of this, it is believed that some elements of the organization remain active in the Big Easy today.

"Junior") in the Patriarca crime family, also known as the New England crime family, the Providence crime family or the Boston crime family.  The Patriarca family is a Mafia crime family based in New England.  Succeeding his father Raymond L.S. Patriarca as boss after his father's death in 1984, Junior was considered a weak leader.  He managed to keep the peace in his crime family due to the support of the Gambino crime family of New York.  When Junior's original underboss Ilario "Larry Baione" Maria Antonio Zannino was sentenced to thirty years in prison in 1987, it further weakened Junior's position.  With Zannino in jail, Grasso became underboss.
