Adela of Normandy
Adela of Blois (c. 1062 - March 8, 1137?) was by marriage countess of Blois, Chartres, and Meaux. She was a daughter of William the Conqueror and the mother of both Stephen, King of England and Henry of Blois, Bishop of Winchester.Her birthdate is generally believed to have been between 1060 and 1064; however, there is some evidence she was born after her father's accession to the English throne in 1066.
She married Stephen of Blois, son and heir to the count of Blois, probably sometime between 1080 and 1084. Stephen inherited Blois, Chartres and Meaux in 1089.
Adela was regent for her husband during his extended absence as a leader of the First Crusade (1095-1098), and it was at least in part at her urging that he returned to the east to fulfill his vow of seeing Jerusalem. She was again regent in 1101, continuing after her husband's death on this second crusading expedition in 1102, for their children were still minors.
