In Frozen (The part not really shown in Once), I believe Anna is Kai/ Gerda. She is still Kai in Once, being a victim of the glass in the eye. The story told by Ingrid about the Trolden Glass is just made for the show. The Mirror made by the trollls is in the orignal source. So, there are rock trolls and there is a mirror, but they seem to not be related. Gerda is names after Gerda of the fairytale. There was somewhere online that someone theorized that Hans was the Mirror in Frozen.

My thoughts.
