[16] Edmund Boyle, Earl of Corke and Orrery, married ---- Courteney, daughter of Lady Frances Courteney, only sister of John Earl of Sandwich. [The marriage being afterwards dissolved, he married the Hon. Mary Monckton, who long survived him. He died in 1798.--E.] [17] William Duke of Devonshire married Lady Charlotte Boyle, second daughter and co-heiress of Richard Boyle, last Earl of Burlington, Lord Treasurer of Ireland. [18] William Ponsonby, Earl of Besborough, married Lady Caroline Cavendish, eldest daughter of William third Duke of Devonshire. Lord Besborough had been at Constantinople with Lord Sandwich. [He died in 1793, and was the grandfather of the present Earl.--E.] [19] What authority Walpole had for this assertion does not appear. The Duke was without ambition, and content to live as an English nobleman on his splendid domain. He died in 1729.--E. [20] Dr. Johnson, a violent political opponent, observed of him, “that he was not a man of superior abilities, but he was a man strictly faithful to his word. If, for instance, he had promised you an acorn, and none had grown that year in his woods, he would not have contented himself with that excuse. He would have sent to Denmark for it. So unconditional was he in keeping his word--so high as to the point of honour.”--Boswell’s Life of Johnson, vol. iii. p. 167. The same lofty feelings characterised his public life, and caused him to be implicitly trusted by the great party of which, without his own seeking, he was the undisputed head. Lord Waldegrave seems to have entertained no mean opinion of his talents.--Memoirs, p. 86. He was Lord Lieutenant of Ireland in 1737, and afterwards remained for a time in the Cabinet; but he accepted office with reluctance, and quitted it with disgust, for he loved his ease and scorned all the arts of intrigue. He died in 1755, aged fifty-seven.--E. [21] Lord George Cavendish filled the place of Comptroller of the Household in 1762, and for some years represented Derbyshire. He had sufficient sense to speak respectably in Parliament. He died unmarried in 1794.--E. [22] Lord Frederick Cavendish had frequently distinguished himself during the Seven years’ war as an excellent cavalry officer. In one of the last affairs of the campaign of 1762, he gained great credit by his spirited behaviour on the 6th of July, when, under the command of Lord Granby, he defeated a considerable body of the French stationed at Horn in order to preserve the communication of the main body with Frankfort, the result of which defeat was the evacuation of Gottingen. He attained the rank of Field-Marshal, and died unmarried at an advanced age in 1803.--E.
