Kennedys made their fortune from bootlegging.
Old Joe made a lot of money in early Hollywood.
I believe I read that he and Ethel went on a cruise and other the other side of the boat was Gloria Swanson (thanks to Old Joe!). So he would run to one side boink Gloria & then run back to the other side and look respectable with Ethel whenever he needed to do that. According to the story Ethel knew about this (and knew about all his affairs)! She was seen giving her Rosary a workout the entire trip!
The Kennedy’s - style man style !
