(Quarterly, 1st & 4th: Azure, three fleurs de lis or (
France); 2nd & 3rd: Gules, three
lions passant guardant in pale or (
England)) all within a bordure compony argent and azure for
difference'' At some time after 1421, Thomas de Courtenay married
Lady Margaret Beaufort, daughter of
John Beaufort, 1st Earl of Somerset (the first of the four illegitimate children of
John of Gaunt (son of King
Edward III of England) by his mistress,
Katherine Swynford, later his wife) by his wife,
Lady Margaret Holland. Margaret was thus the sister of
Henry Beaufort, 2nd Earl of Somerset, of
John Beaufort, 1st Duke of Somerset, of
Thomas Beaufort, Count of Perche, of
Joan Beaufort, Queen of Scotland, and of
Edmund Beaufort, 2nd Duke of Somerset. Thomas and Margaret had three sons and six daughters: •
Thomas Courtenay, 6th/14th Earl of Devon (1432 – 3 April 1461), was taken prisoner at the
Battle of Towton, and beheaded at
York on 3 April 1461, when the earldom was forfeited. • Sir Henry Courtenay (d. 1467/9), Esquire, of
West Coker,
Somerset, beheaded for treason in the market place at
Salisbury,
Wiltshire on 17 January 1469 (or 4 March 1467). As the earldom had been forfeited following the execution of his elder brother in 1461, he is not generally considered to have inherited from him the title "Earl of Devon", although for example, ''
Debrett's Peerage'', 1968, gives him as the 7th Earl and successor to his brother. •
John Courtenay, 7th/15th Earl of Devon (1435 – 3 May 1471), was restored to the earldom in 1470 by the
Lancastrians in exile, and later slain at the
Battle of Tewkesbury on 4 May 1471. • Joan Courtenay (born c. 1441), who married, firstly, Sir Roger Clifford, second son of
Thomas Clifford, 8th Baron de Clifford, who was beheaded after the
Battle of Bosworth in 1485. She married, secondly, Sir William Knyvet of
Buckenham,
Norfolk. • Elizabeth Courtenay (born c. 1449), who married, before March 1490,
Sir Hugh Conway. • Anne Courtenay. • Eleanor Courtenay. • Maud Courtenay. • Agnes Courtenay (1452 – 7 January 1485), who married Richard Saunders (1452–1480) of
Charlwood, Surrey.
Monument to Margaret Beaufort An effigy identified by tradition as "little choke-a-bone", Margaret Courtenay (d. 1512), an infant daughter of
William Courtenay, 1st Earl of Devon (1475–1511) by his wife Princess Catherine of York (d. 1527), the sixth daughter of King
Edward IV (1461–1483) exists in
Colyton Church in Devon. The Courtenay residence of
Colcombe Castle was in the parish of Colyton. However, modern authorities have suggested, on the basis of the monument's heraldry, the effigy to be Margaret Beaufort (c. 1409 – 1449), the wife of Thomas de Courtenay, 5th Earl of Devon (1414–1458). The effigy is only about three feet in length, much smaller than usual for an adult. The face and head were renewed in 1907, and are said to have been based on the sculptor's own infant daughter. A 19th-century brass tablet above is inscribed:
"Margaret, daughter of William Courtenay Earl of Devon and the Princess Katharine youngest daughter of Edward IVth King of England, died at Colcombe choked by a fish-bone AD MDXII and was buried under the window in the north transept of this church".
Heraldry Three sculpted heraldic shields of arms exist above the effigy, showing the arms of Courtenay, Courtenay
impaling the
royal arms of England and the royal arms of England. Later authorities have suggested, on the basis of the monument's heraldry, the effigy to be the wife of Thomas de Courtenay, 5th Earl of Devon (1414–1458), namely Lady Margaret Beaufort (c. 1409 – 1449), daughter of
John Beaufort, 1st Marquess of Somerset, 1st Marquess of Dorset (1373–1410),
KG (later only 1st Earl of Somerset) (the first of the four
illegitimate children of
John of Gaunt, 1st Duke of Lancaster (4th son of King
Edward III), and his mistress
Katherine Swynford, later his wife) by his wife
Margaret Holland. The basis of this re-attribution is the supposed fact that the "royal arms" shown are not the arms of King Edward IV, but rather the arms of Beaufort. The arms of Beaufort are the royal arms of England
differenced within a bordure compony argent and azure. The relief sculpture does indeed show a border, albeit a thin one and not compony, around the royal arms, with such border omitted from the Courtenay arms. ==Death==
