'The Right Hon. William Courtenay, D.C.L., tenth Earl of Devon, and a Baronet, High Steward of the University of Oxford, and a Governor of the Charter House, whose death took place on the 19^th [March 1859] at Shrivenham, at the rectory of his sister's husband, Archdeacon Berens, was the elder son of the Right Rev. Henry Reginald Earl Courtenay, Bishop of Exeter, by his wife, the Lady Elizabeth Howard, daughter of Thomas, second Earl of Effingham, and was born Jun 19, 1777. His Lordship was educated at Christ Church, Oxford, and was called to the Bar in 1799. He was M.P. for Exeter from 1812 to 1826, when he was appointed Clerk Assistant to the Parliaments, an office which he held until his accession to the Peerage, which he inherited on the 26^th May, 1835, when he succeed his [second] cousin, William, the ninth Earl, in his newly-discovered Earldom of Devon, and his Baronetcy, the Viscountcy of Courtenay, then becoming extinct. He married, first, the 29^th of November, 1804, the Lady Harriet-Leslie, daughter of Sir Lucas Pepys, Bart., and his wife, the Countess of Rothes, and by her (who died the 16^th of December, 1839) he had issue three sons and one daughter. His second son, Henry-Hugh, is Rector of Mamhead, Devonshire; and his youngest son is Canon of Windsor, and Chaplain in Ordinary to the Queen. His Lordship's daughter, Harriet-Elizabeth, died unmarried in 1826. The Earl of Devon married, secondly, the 30^th of January, 1849, Elizabeth-Ruth, daughter of the late Rev. John Middleton Scott, and niece of the Earl of Meath, by which lady, who survives him, he has no issue. The Earl is succeeded by his eldest son, William-Reginald, now eleventh Earl of Devon, late Secretary to the Poor Law Board, who was born in 1807, and married, in 1830, the Lady Elizabeth Fortescue, daughter of Hugh, first Earl Fortescue, and has surviving issue a son and a daughter.'
