I don't know. Both Helga/Gerda and Anna were Auburn haired, not blonde.

As for Royal Blood, the Nobles have more than their fair share of dalliances, with many illegitimate offspring, and many are not recognized by their noble fathers. one or two generations, and that bastard child's family is no different than any other commoner or peasant family. Particularly if the bastard child was female. It is possible that David is forth or fifth generation removed from nobility, particularly if that bloodline is passed maternally.

Point being that Emma could very well be related Elsa, but we'll never know. Emma has as much chance of being related to Elsa as I have of being related to Queen Elizabeth.
