Her father was de facto ruler of England together with his mistress Isabella of France, Queen consort of King Edward II, until his eventual capture and execution by the orders of King Edward III, eldest son of Isabella and King Edward II.[1] The latter had been deposed in November 1326, and afterwards cruelly murdered by assassins acting under the orders of Mortimer and Queen Isabella. Katherine was sixteen years old when her father was hanged, Tyburn, London on 29 November 1330.
Beauchamp had succeeded to the earldom at the age of two, therefore Katherine was styled Countess of Warwick from the time of her marriage until her death. The marriage had been arranged in July 1318 to settle a quarrel between the two families over the lordship of Elfael, which was thus given to Katherine as her marriage portion.[3] For the term of his minority, Beauchamp's custody had been granted to Katherine's father, Roger Mortimer.[4]
Katherine later became an important personage at the court of King Edward III. As a sign of royal favour she was chosen to stand as one of the godmothers, along with Queen Philippa of Hainault, to the latter's granddaughter, Philippa, Countess of Ulster, in 1355. This honour bestowed on Katherine is described by 19th century author Agnes Strickland according to the Friar's Genealogy: "Her [Philippa, Countess of Ulster] godmother also was of Warwick Countess, a lady likewise of great worthiness".[5]
