I know these events occured a long time ago, but something bugs me:the relatively recent death of Rosemary Kennedy, John's sister who passed away sometime ago.  It is told that she didn't get in the Kennedy's mold and that when she was young, she was a kind a rebel wanting to party,thus disrupting the family image; so they had her lobotomized, said (?) it didn't succeed but she never appeared after that so she was effectively shut up.

Everybody kind of believe that the Kennedy made their immense fortune through their definite link with the mafia (?) and they were extremely rich and powerful at that  time and they also have been very much involved in american politics.

Jacqueline Bouvier who married John Kennedy, the president (isn't his murder some kind of unsolved mystery even now ?) seems to have been very wise in marrying Onassis afterwards, one of the richest man on the planet then, thus making herself totally untouchable by the Kennedy's...

What really is this Kennedy's curse with all these deaths in their family (anything to do with the mafia by any chance ?)

Is everything I have written so far urban legend?, part truth ? or just gives hints at a bigger unknown truth ? I am truly interested to know, and, by the way I'm not in conspiracies theories.
