Context: Aniello John "Neil" Dellacroce (March 15, 1914 – December 2, 1985), also known as "Mr. Neil," "Father O'Neil" and "The Tall Guy", was an Italian-American gangster and underboss of the Gambino crime family.

American Fletcher National Bank was an Indianapolis-based bank founded in 1839 that was eventually absorbed by Bank One and later Chase Bank.  Since the merger of the Fletcher Trust Company with the American National Bank to form the American Fletcher National Bank and Trust Company at the end of 1954, it had been the largest or the second largest bank in the state of Indiana, often changing places with its Indianapolis-based rival Indiana National Bank for the top spot.  From the mid-1950s through the late 1980s, American Fletcher National Bank and Trust, along with Indiana National Bank and Merchants National Bank, was one of the top three largest banks within Indianapolis and its holding company, American Fletcher Corporation, was one of the top three largest bank holding companies within the state, along with INB Financial Corporation (formerly Indiana National Corporation) and Merchants National Corporation. The Park National Bank is the lead bank in the $5.5 billion Park National Corporation () serving Ohio and Northern Kentucky.

The Genovese crime family (pronounced ] ) is one of the "Five Families" that dominate organized crime activities in New York City and New Jersey as part of the Mafia (or "La Cosa Nostra").  The Genovese crime family has been nicknamed the "Ivy League" and "Rolls Royce" of organized crime.  They are rivaled in size only by the Gambino crime family and are unmatched in terms of power.  They have generally maintained a varying degree of influence over many of the smaller mob families outside New York, including ties with the Philadelphia, Patriarca, and Buffalo crime families. Franklin National Bank, based in Franklin Square in Long Island, New York was once the United States' 20th largest bank.  On October 8, 1974, it collapsed in obscure circumstances, involving Michele Sindona, renowned Mafia-banker and member of the irregular freemasonic lodge, Propaganda Due.  It was at the time the largest bank failure in the history of the country. Power on Earth is a biography of Mafia-linked Italian banker and accused murderer Michele Sindona written by Nick Tosches.  Based on his own in-depth research, including several interviews with Sindona himself while he was in prison awaiting trial, Tosches tells Sindona's rise from poor beginnings to becoming one of the world's most powerful bankers.  It also details his connections with the Gambino crime family, the Vatican Bank, the Franklin National Bank in Long Island, New York, and the murder of Giorgio Ambrosoli, a lawyer overseeing the liquidation of his banks. Banco Ambrosiano was an Italian bank that collapsed in 1982.  At the centre of the bank's failure was its chairman, Roberto Calvi and his membership in the illegal Masonic Lodge Propaganda Due (aka P2).  The Institute for the Works of Religion, commonly known as the Vatican Bank, was Banco Ambrosiano's main shareholder.  The Vatican Bank was also accused of funneling covert United States funds to Solidarity and the Contras through Banco Ambrosiano. Operation Old Bridge is the code name for the February 7, 2008 arrests in Italy and the United States that targeted the Gambino crime family.  Among the indicted were the reputed acting bosses Jackie D'Amico, Nicholas Corozzo and Consigliere Joseph Corozzo of the Gambino crime family.  The indictments included: murder, drug trafficking, robbery and extortion. Alphonse "Funzi" Sisca (Born in 1942 or 1946) is the head of the Gambino crime family New Jersey crew.  Sisca was an ally of John Gotti and started a drug dealing operation with Angelo Ruggiero and Arnold Squitieri.  Sisca was arrested along with other Gambino members for conspiracy.  Sisca also pleaded guilty for racketeering charges on March 31, 2006.  Sisca became New Jersey Faction Leader for the Gambino crime family in 2012. William "Wild Guy" Grasso was an Italian-American gangster from East Haven, Connecticut who served as underboss to Raymond Patriarca, Jr. (a.k.a. "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.
