Katherine Mortimer, Countess of Warwick (1314 – 4 August 1369) was the wife of 
Thomas de Beauchamp, 11th Earl of Warwick KG, an English peer, and military 
commander during the Hundred Years War. She was a daughter and co-heiress of 
Roger Mortimer, 1st Earl of March and Joan de Geneville, Baroness Geneville.

Sometime before 1355, she became an important figure at the royal court of King 
Edward III.
Family and lineage[edit]

Katherine Mortimer was born at Ludlow Castle, Shropshire, England, in 1314, one of 
the twelve children and a co-heiress of Roger Mortimer, 1st Earl of March and Joan de 
Geneville, Baroness Geneville. Her paternal grandparents were Edmund Mortimer, 2nd 
Baron Mortimer and Margaret de Fiennes, and her maternal grandparents were Sir 
Piers de Geneville, of Trim Castle and Ludlow, and Jeanne of Lusignan.

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. 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.

Marriage[edit]

On 19 April 1319, when she was about five years-old, Katherine married Thomas de 
Beauchamp, 11th Earl of Warwick, eldest son of Guy de Beauchamp, 10th Earl of 
Warwick and Alice de Toeni.[1] Their marriage required a Papal dispensation as they 
were related within the prohibited third and fourth degrees. 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 in order to settle a quarrel between the two families over the 
lordship of Elfael, which was thus given to Katherine as her marriage portion.[2] For 
the term of his minority, Beauchamp's custody had been granted to Katherine's father, 
Roger Mortimer.[3]

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".[4]

Katherine and Beauchamp together had fifteen children:[5]
