Corrected entry: The correct name of the second child of the Duke and Duchess of York (younger sister to (now) Queen Elizabeth) was "Princess Margaret Rose". She is incorrectly mentioned in the film as simply "Princess Margaret" a name by which she did not come to be known until she became an adult.

Correction: I suppose you are referring to the fact that her father calls her "Princess Margaret". Even though she was officially known as "Princess Margaret Rose", her family and friends might have called her only "Princess Margaret" on occasion.
