“ Sutton was the son of another John de Sutton, who had inherited Dudley Castle through his marriage with Margaret, sister and heiress of John de Somery (d. 1321) ; he was called Lord Dudley, or Lord Sutton of Dudley, the latter being doubtless the correct form. However, his descendants, the Suttons, were often called by the name of Dudley; and from John Dudley of Atherington, Sussex, a younger son of John Sutton, the 5th baron, the earls of Warwick and the earl of Leicester of the Dudley family are descended. ”

“ John Sutton or Dudley (c. 1400–1487) , the 5th baron, was first summoned to parliament in 1440, having been viceroy of Ireland from 1428 to 1430. He served Henry VI. as a diplomatist and also as a soldier, being taken prisoner at the first battle of St Albans in 1455, but this did not prevent him from enjoying the favour of Edward IV. He died on the 30th of September 1487. He was succeeded as 6th baron by his grandson Edward (c. 1459–1532) , and one of his sons, William Dudley, was bishop of Durham from 1476 until his death in 1483. ”
