Ok, a few things here. First, SK, I'm pretty sure the quote from MC had to do with the power being handed down through the female line, like, only the princess's could wield it.
Also, in the prequel, with the stained-glass windows, didn't it say the Picori gave the Hero a sword and a golden power? I can't remember totally, but I'll check later today. If so, that would most-likely be the Triforce of Courage, so Zelda couldn't have had the entire Triforce. But like Dark_link01 said, how could the Picori have gotten any of the Triforce?
Didn't Vaati absorb some of the Light Force though? I know in the end, Ezlo said "Zelda may still possess some Light Force" so it sounds like she lost most of it to Vaati. In that case, I suppose it would be unlikely that it was the Triforce of Wisdom, because I don't think Vaati could have taken only a part of that; he'd have to take the whole thing, I'd think.
