Overview
Judith of Lens (born Normandy, between 1054 and 1055 - died Fotheringhay, c. 1090) was a niece of William the Conqueror. She was a daughter of Adelaide of Normandy (Countess of Aumale), sister of William the Conqueror, and Lambert II, Count of Lens.
Life
In 1070, Judith married Earl Waltheof of Huntingdon and Northumbria. They had three children – Maud de Lens aka Matilda (1074-1130), Judith (1075-1137) and Adelese aka Alice (c. 1075/76-1126). Their eldest daughter, Maud, brought the earldom of Huntingdon to her second husband, David I of Scotland. Their daughter, Adelise, married Raoul III de Conches whose sister, Godehilde, married Baldwin I of Jerusalem.
In 1075, Waltheof joined the Revolt of the Earls against William. It was the last serious act of resistance against the Norman Conquest of England. Some sources claim that Judith betrayed Waltheof to the bishop of Winchester, who informed her uncle, the king. Other sources say that Waltheof was innocent and that it was he who notified the bishop and king of the plot. Waltheof was beheaded on 31 May 1076 at St Giles Hill, near Winchester.
