Irish

The McReary Mob is a medium-sized organization, also known as the Irish Mob. It is an Irish-American criminal organization based throughout Liberty City in Grand Theft Auto IV. It is headed by Gerry McReary.

The Irish Mob used to be a powerful force in Liberty City, but its influence has diminished greatly as of late. The gang used to control Purgatory in Algonquin, as well as most of Broker, but the expansion of the Italian Mafia and Russian Bratva encroached on their empire. Also, most of the gang members have a tendency to spend their money on drugs, alcohol, and women rather than saving it and using it to expand the family's interests. As a result, the gang consists of mostly hired guns.

Gerry has been in and out of prison over the years, significantly damaging any stability the gang hoped to maintain. With Gerry in prison, the leadership has fallen mostly on Patrick McReary ("Packie"), the youngest of the family. Under Packie's control, the gang has been reduced to hired mercenaries for the Pegorino Family, working for the incompetent Ray Boccino, or dealing drugs for the Torres Cartel. Other members include a former provisional IRA member named Derrick McReary, the eldest brother, who has been crippled by heroin addiction. He was in charge of the gang but quickly relinquished control to Gerry, and has since alienated former members Bucky Sligo and Aiden O'Malley by allegedly giving them up to the Liberty City Police Department.

Currently, the gang is involved in armed robbery, extortion, and other unsavoury activities. Other members include Michael Keane and Gordon Sargent. The gang is also discredited by the fact that one of the McReary brothers, Francis, is ambitiously pursuing the job of Chief of Police. Such a connection is greatly damaging to the reputation of both factions.

Niko Bellic also works as a hired gun for the Irish. He was introduced to Packie through a mutual friend, drug kingpin Elizabeta Torres.
