The Queen Katherine of the title is not certainly identified, nor the spelling of the name certain. Up until as recently as the 18th century, people often spelled their own names differently at different times. So while the periods of time with which Robin Hood has normally been associated did not have any queens named Katherine, because the king is sometimes called Henry, she may be meant to be
Catherine de Valois, the young French princess married to King
Henry V of England, hero of Agincourt, or
Katherine of Aragon, placing the story in the time of
Henry VIII. ==Adaptations==
