Cecilia of Normandy

Cecilia of Normandy (or Cecily; c. 1056 – 30 July 1126) was a French abbess, thought to be the eldest daughter of William the Conqueror and Matilda of Flanders. Life She was the sister of William II and Henry I of England. She was very close to her other brother, Robert Curthose. She was given a high education in the arts, Latin, rhetoric and logic by the scholar Arnulf of Chocques. Cecilia was entered into the Abbey of the Holy Trinity of Caen at a young age by her parents. She was placed in the convent in June 1066, at the formal inauguration of the convent, which was founded by her mother as a penance for the marriage, which was initially regarded as a prohibited degree of kinship, as well as during the preparations of the invasion of England.
