But if Goldberry is Galadriel, then what's this business with the "daughter of the River-woman?" Might it not be that Goldberry is in fact Celebrķan, that Galadriel is the River-woman, and the whole business of Celebrķan going off to the West was a convenient fiction Elrond made up to cover for the fact that his wife left him and took up with this "Bombadil" guy? She may be acting as an informer for Mom, so she doesn't need to go trotting off out of Lórien....
