Rapunzel's name
Who gave her the name Rapunzel? I'm assuming it was Gothel, seeing as that was the name of the magic flower she'd been using up until that time, and in the early scenes she even refers to Rapunzel as "flower". Plus if you're going kidnap a newly born child you don't hang around to ask the parents what the name is.
It that is true then Rapunzel would have been known to her true parents by a different name. Anyone know what that might be?
