{54c} Henry Beaufort, Duke of Somerset, was the son of Edmund Beaufort (grandson of John of Gaunt, Duke of Lancaster), who, after the death of his eldest brother, John Beaufort, first Duke of Somerset, without issue male, was created first Marquis of Dorset, and in the twenty-fifth year of Henry VI. was made Duke of Somerset, and was slain at the first battle of St. Alban’s, on the 22nd of May, {54d} 1455, fighting on the part of Henry VI., and had issue by his wife Eleanor, daughter of Richard Beauchamp, Earl of Warwick, four sons and several daughters. The eldest son, Henry was, after his father’s death, Duke of Somerset, Marquis of Dorset, and Lord of Chirk and Chirkland, in the marches of Wales. He was one of the Lancastrian commanders at the battle of Wakefield, and, as there is every reason to believe, also at the second battle of St. Alban’s, although that circumstance is not distinctly mentioned by historians. He was also a principal commander and fought at the battle of Towton; and after the defeat there, escaped into Scotland, and was afterwards pardoned by Edward IV.; but having revolted from Edward to the Lancastrians, and having, with the Lords Roos, Molyns, and Hungerford, Sir Henry Neville, Sir Thomas Wentworth, and Sir Richard Tunstal, fought at the battle of Hexham, he was taken prisoner by John Marquis Montague, and was beheaded in 1463. Edmund, the second son, was also Duke of Somerset after his brother, and was beheaded after the battle of Tewkesbury, in 1471; John, the third son was slain in that battle; and Thomas, the fourth son, died without issue. The family was noted for its strong attachment and exertions in the cause of the House of Lancaster. {54d} The 22nd of May, according to Dugdale, vol. i. pp. 166 and 342; and Sandford, p. 321; but the 23rd of May, according to Hall, Holinshed, and Grafton.
