All five NY families have had a presence in Jersey to one degree or another. The Genovese the most, obviously. I'd say back in the day the Gambino's presence there rivaled the Luccheses. And a porn spot is a little different than, say, the waterfront as far as traditional territory goes. Plus I remember from Murder Machine DeMeo saying Jersey is where a lot of the customers for his child porn/bestiality movies were.
