Camden, in his "Britannia" (vol. 1, p. 559), after referring to this family as having flourished in a continued succession from the coming in of the Normans to the time of Henry VI and then to have failed for want of an heir male of William, 13th Lord d'Eyncourt, adds, "I was the more willing to take notice of this family that I might in some measure answer the desire of Edmund, Baron d'Eyncourt, who was so very earnest to preserve the memory of his name that, having no issue male, he petitioned King Edward II for liberty to make over his manors and arms to whomsoever he pleased; for he imagined that both his name and arms would go to the grave with him and was very solicitous to have them survive and be remembered. Yet this surname, for aught I can find, is now quite extinct and would have been forgotten for ever if the memory of it had not been preserved in books."
Camden does not quite correctly state the license. It is extant and may be found, printed at length, in Ryley's "Plac. Parl." (p. 547). It is dated 23 February 7th Edward II , and enabled Edmund, Baron d'Eyncourt, as will be seen hereafter, to settle his lands upon his grandson William, 2nd son of his eldest son, John d'Eyncourt, in exclusion of Isabel, the female heir, she being the only child of Edmund, eldest son (then deceased) of the said John d'Eyncourt, which Isabel afterwards d. s. p.; and this leads us to trace the family of d'Eyncourt, who were formerly barons by tenure until summoned to parliament by writ, 22nd Edward I .
Edmund, 8th baron, who obtained that remarkable license above mentioned from Edward II. He signed, 12 February, 1301, 29th Edward I, the celebrated letter sent by the barons, assembled in parliament at Lincoln, to Pope Boniface VIII, denying his jurisdiction in temporal affairs, and denying that Scotland was a fief of the Roman see. The duplicate of this letter exists amongst the pubic archives, and the seal of "Edmundus de Eyncourt" thereto appended, is in good preservation and was engraved in 1729, in the 1st vol. of the "Vetusta Monumenta." Baron Edmund was also present, 33rd Edward I , when the king refused permission to the bishop of Durham to present a foreign bishop, on the Pope's recommendation, to the priory of Coldingham. He had two sons, John and William, who were with the feudal army at Carlisle, 29th Edward I , in the place of their father, and figure in the roll of Caerlaverock where John, it is said, 'mult bien fist son devoir." He d. v.p., and subsequently, William, a commander of distinguished valour, was killed 23 June, 1314, 7th Edward II, before the Castle of Stirling, on the eve of the battle of Bannockburn.
Baron Edmund's eldest son, John, left three sons, Edmund, who also d. in the baron's lifetime; William (afterwards 9th baron), and John. Edmund, the grandson, left a dau., Isabel, and the object of the above-mentioned license was to vest the estates in her uncle, William, next brother of her father, Edmund, in order to prevent the barony descending to her and thus passing, in case of her marriage, to another name and family. The youngest brother, John, represented Lincolnshire in parliament, 11th Edward III , and Nottinghamshire, 14th Edward III. Baron Edmund d. 20th Edward II  at a very advanced age. He had immense possessions with great weight and authority; he was prominent in the chief events of his time and attended his sovereigns on all important occasions of war or council. On his decease, his son John, and his grandson Edmund, being dead, and the great-granddau. Isabel being also dead, without issue, William, 9th Lord d'Eyncourt, s. his grandfather, when twenty-six years of age, as heir by descent as well as by virtue of the licensed entail.
