There are a couple of rats name Gerry Denono from Chicago and Joey Cantalupo from New York. Does anyone know anything about them beyond what was mentioned on the series?

Denono also mentions a couple of powerful guys named Johhny DeMarco and Tony DeJohn. Does anyone know anything about them? I've never heard of them. Denono also refers to each of the Chicago crews as "families". Is this common for the Outfit?
