The Castle and Honour of Arundel had been settled on her as her dowry by King Henry I of England, her first husband. He had married her after the disaster of 'The White Ship' when the king's only legitimate son was drowned, leaving him with his only legitimate daughter, the Empress Matilda. Sadly, during the fourteen years till the king's death, no children were born. 

She remained a widow for about three years and then, in 1138, married William d'Aubigny, or de Albini, who then first became known as Earl of Lincoln, then Earl of Chichester, only much later as Earl of Arundel. Several children were born from this marriage.

The Queen Dowager retired in 1150 to a nunnery at Afflighem, in South Brabant, where she died and was buried on 23 April 1151, aged about forty-eight.
