An overview of NY 5 families of organized crime. For each of the families you can see the founder(s) (in ovals) and a list of the most infamous bosses (chronologically). I hope you find it helpful in order to better understand movies or books about gangsterism in NY. For instance, it is helpful to know that "Goodfellas" is about people in the Lucchese family, or that the "Corleone" family is roughly based on the Bonnano family, etc. All pics come from wikipedia. Each main branch also points to the wikipedia page.
