The Morellis are a Mafia family operating in Boston, UCAS, where they share their turf with the O'Rilleys and the Muldoons.

The Morellis used to be the ruling family in Boston but have since been superseded by the O'Rilleys. As the O'Rilleys have the full support of the Muldoons the Morellis have no possibility of changing the status quo.
