Henry Earl J. Wojciechowski, also known as Hymie Weiss (January 25, 1898 – October 11, 1926), was an American mob boss who became a leader of the Prohibition-era North Side Gang and a bitter rival of Al Capone.
 He was known as 'the only man Al Capone feared'.
Ralph "Bottles" Capone, Sr., (January 12, 1894 – November 22, 1974) was a Chicago mobster and an older brother of Al Capone and Frank Capone.
 Ralph Capone got the nickname "Bottles" not from involvement in the Capone bootlegging empire, but from his running the legitimate non-alcoholic beverage and bottling operations in Chicago.
 Further family lore suggests that the nickname was specifically tied to his lobbying the Illinois Legislature to put into law that milk bottling companies had to stamp the date that the milk was bottled on the bottle.
 He was most famous for being named by the Chicago Crime Commission "Public Enemy Number Three" when his brother Al was "Public Enemy Number One".
Edward Joseph O'Hare, aka "Easy Eddie" (September 5, 1893 – November 8, 1939), was a lawyer in St. Louis and later in Chicago, where he began working with Al Capone, and later helped federal prosecutors convict Capone of tax evasion.
 In 1939, a week before Capone was released from Alcatraz, O'Hare was shot to death while driving.
 He was the father of Medal of Honor recipient Butch O'Hare, for whom Chicago O'Hare Airport is named.
