Matilda of Anjou, also known as Mahaut (c. 1111 – 1154) was married in 1119 to William Adelin, son and heir apparent of Henry I of England.
Matilda was the daughter of Count Fulk V of Anjou, and his first wife Ermengarde, Countess of Maine.
[8] Henry maintained that she could remain as long as she wished,[a] and intended to marry her to one of his great nobles, "heaping on her wealth and honours which would have raised her above all her family.
"[8] She remained in England for several years, unmarried, but according to Orderic, wishing to see her parents and home, she returned to Anjou.
[8] After a time in Anjou, Matilda, who had remained a virgin, took the advice of Geoffrey, Bishop of Chartres, and took her vows as a nun at Fontevrault Abbey.
