Marian of Knighton

Lady Marian, portrayed by Lucy Griffiths, is the daughter of the former sheriff of Nottingham (Edward of Knighton). In contrast to most Robin Hood legends, is not described as Maid Marian, but rather Lady Marian. "In those days would be considered quite old to still be a maid," actress Lucy Griffiths explained in the Radio Times preview.

She was engaged to Robin before he went to fight in the crusades and is visibly cold and aloof toward him on his return, although in episode twelve she admits that she considered him a hero even while calling him a fool. She initially disapproved of Robin's outlaw status because she believed that the best way to fight injustice was to work inside the system. However, she aids him in his fight against the Sheriff by frequently spying for him and manipulating Gisborne. Marian also fights the Sheriff in her own right, disguising herself as the Night Watchman and giving the poor food and supplies.
