She was the widow of ROBERT DE BEAUMONT, count of Meulan and Earl of Leicester. It is commonly stated that before the count's death she eloped with WILLIAM DE WARENNE, whom she later married. However,
see the following note.
Cokayne's "Complete Peerage" (Leicester, p.526 and notes b and d). Henry of Huntingdon states that she eloped with a certain earl during ROBERT's lifetime, which may refer to some scandal, but the whole trend of the letter does not inspire confidence in the facts stated therin.

Towards the invading fleet he contributed, according to Taylor's List, sixty vessels, and being at that time advanced in years, and selected to superintend the affairs of the duchy, sent his young son Robert to win his spurs at Senlac. In that memorable battle he is said to have given proof of courage and intelligence beyond his years, and promise of the high reputation he would eventually obtain, and which won for him the surname of Prudhomme. "A certain Norman young soldier," writes William of Poitou, "son of Roger de Bellomont, and nephew and heir of Hugh, Count of Meulent, by Adelina, his sister, making his first onset in that fight, did what deserves lasting fame, boldly charging and breaking in upon the enemy with the troops he commanded in the right wing of the army."
