As we all know: coincidences don't exist in anime and manga (and other stories for that matter).

I'd say we keep it just Euria, since the full name hasn't been confirmed officially. Though it could be mentioned in the trivia. "As the sister of Marribel, her full name could be Euria mel Britannia" or something like that.
