According to author Gore Vidal, his step-sister, Jackie Kennedy...
Wait a minute. How on earth are these two step-siblings? Let's see.
Vidal's mother, Nina Gore, was the second wife of Hugh Auchincloss. Auchincloss' third wife was Janet Lee Bouvier, Jackie's mother. (This was Janet's second of three marriages.) So yeah, we guess one can call them step-siblings. And they're also supposedly cousins. And they say Jewish ancestry is hard to figure out.
Anyway, according to Vidal, Jackie was part Jewish. Supposedly, Jackie's mother, who was born Janet Lee, was really Janet Levy, with her father (Jackie's grandfather) anglicizing his name to become a vice president of the Morgan bank. Vidal's mother made sure to point that out.
Now, normally when we would take a relative's word, but here it seems a bit fishy. So we dug up Jackie's ancestry, and it looks that not only was her grandfather was born James Lee (not Levy), HIS father (Jackie's great-grandfather) was also James Lee. So either the Levy origins are REALLY well hidden, or Vidal's mother was just jealous of the woman who replaced her.
Oh, those petty socialites!
