Gerloc (or Geirlaug), baptised in Rouen as Adela (or Adèle) in 912, was the daughter of Rollo, of Normandy, Count of Rouen, and his wife, Poppa of Bayeux. She was the sister of William I Longsword of Normandy.
In 935, she married William Towhead, the future Count of Poitou and Duke of Aquitaine. They had two children together before she died on 14 October 962:
Adelaide of Aquitaine, wife of Hugh Capet.
Following the marriage, Willian Longsword requested monks from Aquitaine to help rebuild Jumièges Abbey. Twelve Monks came from the Abbey of Saint-Cyprien in Poitiers, led by their abbot Martin of Jumièges.
