Henry Stelli is the illegitimate son of Martin and Angelina Torelli. Martin is the second-youngest son of current boss James Jr., and has lived in the Torelli hometown of Messina, Sicily for much of his life, maintaining a connection to the Sicilian Cosa Nostra.
In 1998, Martin's mistress Angelina gave birth to Henry in Messina. Fearing backlash from his fiancée Maria, he sent Angelina and the newborn Henry to upstate Liberty, where they settled in Albany.
Henry grew up in a lower-middle class neighborhood of Albany, and in his teenage years, got involved with a sub-crew of the Philadelphia crime family, led by soldier John Amendola, working primarily alongside associate Matthew Catalano.
The crew maintained close connections to the Marchesi crew, an already extant Philadelphia cell active in Vespucci Beach, in Los Santos.
Starting in 2018, members of the Amendola crew began to gradually move over to Vespucci Beach, including Henry. They were active in sports betting, car theft, prostitution and extortion.
