Born Trapani, Sicily, 1905.
Died Smithtown, NY, June 11, 1970.
DiGregorio, an in-law of the Bonannos and Magaddinos, was a clothing manufacturer and a prominent member of the Bonanno Crime Family in New York City. DiGregorio reportedly served as best man in Joseph Bonanno's wedding and was godfather to Bonanno's oldest son Salvatore (Bill).
DiGregorio was a native of Trapani, Sicily. He entered the U.S. through Canada in 1921. He married the sister of Buffalo crime boss Stefano Magaddino. After her death, he remarried.
With support from Magaddino, DiGregorio seized control of the Bonanno crime Family after Joe Bonanno disappeared in the early 1960s. Joe Bonanno's son fought the takeover and the so-called Banana Wars were the result.
Joe Bonanno re-emerged in 1966 and promised to get his Family in order. The Commission, which had initially welcomed DiGregorio's takeover of the Bonanno clan (Carlo Gambino, Tommy Lucchese, Stefano Magaddino and Joe Colombo likely encouraged DiGregorio in order to destablize the Bonannos who often stood in their way), quickly withdrew their support.
DiGregorio was ousted, suffered heart attacks and became entirely unimportant in the underworld. His rebellious faction within the Bonanno Family was briefly led by Paul Sciacca.
After several years of quiet living with family on Long Island, DiGregorio succumbed to lung cancer at St. John's Hospital in Smithtown on June 11, 1970. He was buried in St. Charles Cemetery in Farmingdale.
