William West, 1st Baron De La Warr

According to Riordan:[5]

[In 1549 the 9th Baron] placed a private bill before parliament to disinherit his nephew William West, first Baron De La Warr (c.1519–1595). The latter was the son of the ninth baron's half-brother Sir George West of Warbleton (d. 1538) and his wife, Elizabeth, daughter of Sir Robert Morton of Lechlade, Gloucestershire. His uncle was childless, and had at some time adopted William as his heir. However, West tried to gain the de la Warr estate early by poisoning his uncle. The attempt was unsuccessful and he was in the Tower by October 1548. He was disinherited by an act of parliament in 1550, although he had been reinstated as heir by the time of his uncle's death.

Despite the fact that he had been reinstated as heir by his uncle, when the latter died in 1554 William West was unable to inherit the barony of de la Warr as a result of the Act of Parliament of 1550 which had deprived him of all honours. Two years later he was involved in the Henry Dudley conspiracy, and on 30 June 1556 was arraigned at the Guildhall on charges of treason, to which he responded as 'William, Lord de la Warr', forcing the heralds to prove during the trial that he was not entitled to the barony and therefore not entitled to a trial by his peers in the House of Lords. He was convicted of treason. However the death sentence was not carried out, and in 1557 he was pardoned by Queen Mary. He fought at the siege of St. Quentin in that year, and in 1563, early in the reign of Queen Elizabeth, was restored in blood. On 5 February 1570 he was knighted, and on the same day created Baron De La Warr, which was regarded as a new creation of the title.[5]

West took part as a peer in the trials and convictions of Thomas Howard, 4th Duke of Norfolk and, later, his son, Philip Howard, 20th Earl of Arundel.

He was a junior peer in his lifetime, as the latest created. However, his son and descendants have been seated with the precedence of 1299, as though they had inherited his uncle Thomas's title. By the modern rules of the House of Lords, his uncle's title fell into abeyance between the daughters of William West's second uncle, Sir Owen West, or their heirs; however, as Cokayne notes, such rules are at best modern approximations to actual medieval practice. What seems clear is that some, but not all, writers treat the letters patent as clarifying the descent of the ancient title, rather than creating a new one, hence William is sometimes referred to as 10th baron.

He married Elizabeth Strange and was the father of three sons and three daughters, Jane, Elizabeth, and Mary. Jane West married firstly Thomas Wenman, secondly James Cressy, and thirdly Thomas Tasburgh (c.1554 – c.1602), of Hawridge, Buckinghamshire.[6] She was the mother of Richard Wenman, 1st Viscount Wenman.

West was succeeded as Baron De La Warr by his son Thomas West, 2nd Baron De La Warr.[7]

West married firstly, before 1555, Elizabeth Strange, the daughter of Thomas Strange of Chesterton, Gloucestershire, by whom he had three sons and three daughters:[8]
