From Wikipedia:
"Geoffrey and Matilda's marriage took place in 1128. The marriage was meant to seal a lasting peace between England, Normandy (an English possession since William I) and Anjou. She was eleven years older than Geoffrey, and very proud of her status as dowager Empress (as opposed to being a mere countess), and which she kept for the remainder of her life. Their marriage was a stormy but happy one with frequent long separations; she bore him three sons and survived him by over 15 years."

1. Henry PLANTAGENET, II, b. Mar 1132/33, Le Mans, France d. 7 Jul 1189, Chinon, France (Age 56 years)
When Matilda's first husband died, her father gave her in marriage to a 16-year-old teenager, Geoffrey of Anjou.
Matilda was named as successor to the throne by her father, King Henry I. However, when he died, the Council offered the throne to her cousin, Stephen of Blois, who proved to be a weak king. At one point her father's illegitimate son, Earl Robert, gave his support to Matilda, who installed herself as monarch at Arundel. The nobles took sides and a decade of civil war ensued. Eventually the crown passed to Matilda's son, Henry Plantagenet.
