Alice de Lusignan of Angoulême

Alice de Lusignan (or Alice of Angoulême) (born after October 1236 – May 1290) was the first wife of Marcher baron Gilbert de Clare, 6th Earl of Gloucester and half-niece of King Henry III of England.

It was rumoured that she became the mistress of her half first cousin Prince Edward, while she was briefly imprisoned on account of her husband's treason.

Alice de Lusigan was born sometime after October 1236 in Angoulême, Charente, France, the daughter of Hugh XI of Lusignan, Seigneur de Lusignan, Couhe, et de Peyrat, Count of La Marche and Angoulême, and Yolande de Dreux, Countess of Penthièvre and of Porhoet, and sister of Hugh XII of Lusignan. By her paternal grandmother, Isabella of Angoulême, Queen-Consort of King John of England, she was niece, in the half blood, of Henry III.

She arrived in England on an unrecorded date. On 6 April 1250, her father was killed in battle at Fariskur, Egypt. In 1253, Alice married Gilbert de Clare, 7th Earl of Gloucester (2 September 1243 – 7 December 1295). He was the son of Richard de Clare, 6th Earl of Hertford and Maud de Lacy. He was ten years old at the time of his marriage. In later years, "Red" Gilbert would become one of the most powerful and important noblemen in the kingdom. The marriage produced two daughters.
