Adela of Normandy, by marriage countess of Blois (b. c. 1067)
Adela of Normandy, of Blois, or of England (c. 1067 – 8 March 1137), also known as Saint Adela in Roman Catholicism, was a daughter of William the Conqueror and Matilda of Flanders who later became the countess of Blois, Chartres, and Meaux by marriage to Stephen II of Blois. Her husband greatly benefited from the increased social status and prestige that came with such a marriage. She brought with her not only her bloodline, but a dowry of money and other movable goods from the prodigious store of Anglo-Norman wealth. She was regent of Blois during the absence of her spouse in 1096–1100 and 1101–02, and during the minority of her son from 1102 until 1120. Adela was the mother of King Stephen of England and Bishop Henry of Winchester.
