From Wikipedia, the free encyclopedia
Margaret de Newburg, Countess of Warwick (? – 3 June 1253), was the daughter of Henry de Beaumont, 5th Earl of Warwick and Margaret D'Oili. She was sister and heiress of Thomas de Beaumont, 6th Earl of Warwick.
She married first John Marshal, Earl of Pembroke, and secondly John du Plessis. The latter was a great favourite with Henry III and in 1247, he created him the seventh Earl of Warwick and subsequently Count of Warwick; he died 20 February 1263. There was no issue by either of these marriages and at Margaret's death the estates passed to her cousin William Maudit.
