Gytha
From Tardis Wiki, the free Doctor Who reference
Countess Gytha was the mother of King Harold. She and her daughter-in-law Edith Swan-Neck falsely identified the body of her son on the battlefields of Hastings on 14 October 1066.
This lie allowed her son to be "reborn" as Hereward the Wake, a formidable Saxon guerilla warrior. (PROSE: The Real Hereward)
