Giuseppe Profaci is born in Villabate, in Palermo province, on 2 October 1897. He is suspected of already being involved in the Mafia in Sicily, where he served a year in a Palermo prison for theft.
At least two sources indicate Joe Profaci immigrates from Sicily on 4 September 1921. One source names the ship, the SS Providence. Another source indicates he is traveling with future boss Vincent Mangano and Vincent's brother and father. A search on SteveMorse.org for a matching travel date finds the SS Providence departing Palermo on 24 August 1921 and arriving 4 September 1921 in New York. Appearing on the manifest are:
10. Gaetano Mangano, 39 (b. 1882), married, a merchant, leaves his wife Giovanna Giannone behind in Palermo. Destination NY, his brother in law Francesco Giannone, at 25 West Broadway (near World Trade Center site in Tribeca)
11. Vincent Mangano, son, 14 (b. 1907), student Dest NY as above. “Claims US born”. Giovanna Giannone is his mother.
12. Giuseppe Profaci, 24 (b. 1897), single, merchant, leaves his father, Giuseppe behind in Palermo. Dest NY, his cousin Calogero Profaci at 225 Elizabeth St (in lower Manhattan near Little Italy).
Joe settles first in Chicago, and then moves to New York in 1925, where he enters the olive oil import business, earning his nickname, "The Olive Oil King." In Mario Puzo’s books, Vito Corleone forms the "Genco Pura Olive Oil Company" in the 1920s. This detail is lifted right out of Profaci’s life.
Profaci's relationship with Mangano allows him to build relationships with other gang leaders in New York. Besides his legitimate operation in olive oil import, Profaci is also involved in extortion, bootlegging, counterfeiting, prostitution, loan sharking, narcotics trafficking, and gambling.

Joe and Nina have six children, according to Wikipedia, including two sons: John Jr, and Frank. Frank joins his father's crime family, now known as the Colombo Family, while John Jr. enters legitimate business. According to a profile of John Jr., he has three brothers in business with him at Colavita USA: Joseph, Anthony, and Robert. Joe has at least one daughter, who marries a gangster from Detroit.
Nina’s brother, Joseph, becomes Profaci’s long time underboss.
Olive oil is a rationed food in the latter years of World War II, when trade embargoes make it impossible to source legitimate, Italian olive oil. Demand skyrockets after the war.
