Princess Mary - daughter of Henry VIII and Catherine of Aragon - was reputedly completely ignorant of any foul words or phrases. It has been reported that she did not know the word "whore" until she ascended to the throne - however this seem unlikely. After all, Mary did not life in a closely fitted bubble and foul words have probably found their ways to the innocent Princess' ears. It is more likely that she simply did not utter the bad words until she wore the crown herself.
For example she is known to have called a lady-in-waiting of hers a whore after the discovery of an intimate affair.
