There are three well-known D'Andreas who were connected with organized crime in Chicago. The first was Joseph D'Andrea. He was killed in the 1910s after leaving a union meeting. He was the president of several unions, such as the Hod Carriers Union, and was also connected with Jim Colosimo, Al Capone's predessessor. He also killed a man, allegedly in self-defense, in the early 1900s. His brother Anthony D'Andrea was involved in counterfeiting and was sent to prison for 18 months. Later he also became a union leader and in 1919 became the president of the Chicago chapter of the Unione Siciliana. He was also believed to be the Mafia boss of Chicago. After running for political office, he was killed in 1921. Another brother, Louis, did work for Anthony, and a fourth brother, Horace, was a Roman Catholic priest. Anthony was a de-frocked priest who attended the University of Palermo.
A nephew of Anthony, Phil D'Andrea, was a bodyguard for Al Capone, a capo under Frank Nitti, a president of the Italo American National Union in Chicago from 1931 to 1941, and went to prison in 1943 for extorting Hollywood studios. He retired from crime and lived out his last days in Riverside, California.
