Posthumous daughter of King Alexander of Greece and his morganatic wife, Aspasia Manos, Alexandra was not part of the Greek royal family until July 1922 when, at the behest of Queen Sophia, Alexander's mother, a law was passed which retroactively recognized marriages of members of the royal family, although on a non-dynastic basis; in consequence, she obtained the style and name of Her Royal Highness Princess Alexandra of Greece and Denmark.
