Who married John De Burgh?

Elizabeth de Clare, 11th Lady of Clare (16 September 1295 – 4 November 1360) was a member of the Anglo-Norman family, de Clare, and heiress to the lordships of Clare, Suffolk, in England and Usk in Wales.

She is sometimes referred to as Elizabeth de Burgh (English: də-BUR), due to her first marriage to John de Burgh. Her two successive husbands were Theobald II de Verdun (of the Butler-de Verdun family) and Roger d'Amory.

Later in life, Elizabeth, as a widow, was a religious and educational benefactress, mainly to establishments in East Anglia. These included the second-oldest surviving college of the University of Cambridge, Clare College, which took its name after her.
