How Hillary met Hillary

Was she named (with a double L) for Sir Edmund Hillary or not? Snopes reviews all the evidence. Sometimes the stories your parents tell you are just that. My mother told me my dad chose my name for a popular movie star of the 1930s, and No it wasn't Norma Jean, since she was just an unknown then. Norma Talmadge, of silent films, was already a star when my dad was born, so I suspect it must have been Norma Shearer, if you can believe the stories mothers tell little girls when they're passing the time doing the dishes. But if any film buffs have another suggestion, I'll take a look, because I don't remember.
