Actually there were two Camorra groups in the USA. One was the Neapolitan group that was primarily in New York. It was never large and petered out after a while. Vito Genovese was connected to it (we can't prove that he was a member, but he may have been). There were several "Families" in New York, one in Navy Street, another in Coney Island (they merged), another in Harlem under a Dominick DeLucca and another in Little Italy.

The other Camorra group that was far larger was the Calabrian Camorra. It existed all over the USA in many cities, and Rocco Pellegrino was a member. Today the Calabrian Camorra is known as 'Ndrangheta.
