Nothing is known about the organization's origins. The DeMarcos were peripheral players during the 80s and 90s, working under the umbrella of the Punchinellos, but by 2004, due to the weakening of other crime syndicates such as the Punchinello crime family and Vladimir Lem's Russian Mob, they took advantage of the power vacuum. At some point prior to 2012, Anthony DeMarco became the Don of the Family while his spoiled and arrogant son Tony served as his right-hand man and the Underboss of the Family. It also seems that certain members of the Mafia, such as Tony, TJ and Vincent hang out at Walton's Bar.
Hunting Max PayneEdit
In 2012, Tony DeMarco, the son of the Don and the Family's Underboss, along with a few friends, enter Walton's bar and encounter the former NYPD detective Max Payne. They begin to tease him, though Payne remains relaxed and taunts the thugs back. Tony gets angry, thinking that Payne disrespected his family, and pulls an M1911 to the detective's head. Tony, however, is confronted by Raul Passos, who points a .38 Revolver at the mobster. Tony and his group exit the bar, but tells Payne and Passos that they will return.
A while later, Tony returns with his friends and confronts Max and Raul again. He hits a woman who was drinking with Passos. Max then takes a handgun and kills Tony. A large group of mobsters that were in the bar attack Payne and Passos, but they manage to escape and run to Max's place.
War with PunchinellosEdit
Some time later after Max leaves New Jersey, he spots a newspaper on a yacht in Panama, which states that the DeMarcos and Punchinellos have restarted their animosity towards each other and it has resulted in a turf war in New Jersey, particularly Hoboken.
