A man of impressive pedigree on his mother’s side of the family, Wentworth both flourished and met his end in the service of Henry VI. His maternal grandparents were a prominent knight and a peer’s daughter, and his mother, Margery, the widow of John, Lord Roos. Margery’s match with Roos, who was killed in France at the battle of Baugé, was childless, and she brought to her second marriage with Roger Wentworth the Despenser and Tiptoft lands she had inherited from her parents.
By the late 1430s, perhaps before he had attained his majority, Wentworth was a member of the royal household. Soon held in high favour, in the mid 1440s he was one of the Household men given a jewelled brooch by the queen,
The Ashingdon grant was made during the Parliament of 1447, which Wentworth attended as one of the knights of the shire for Suffolk. Gloucester, a leading critic of the government, had died three days earlier at Bury St. Edmunds, where the assembly was held, shortly after his arrest on trumped up charges of treason. The government, headed by William de la Pole, marquess of Suffolk, had called the Parliament in order to take action against Gloucester, and it had chosen Bury as the venue because it was well away from London where the duke had enjoyed popular support. During the elections to the Commons, it had mobilized its resources to secure the return of its supporters in East Anglia: Wentworth’s fellow knight of the shire for Suffolk was another courtier, William Tyrell I*, and the MPs for the county of Norfolk, Edmund Clere* and John Blakeney*, were also Household men. It is likely that Wentworth, in receipt of a fee of 20 marks p.a. from Suffolk’s widow a few years later,
In the months immediately following the dissolution of the Parliament, Wentworth obtained several grants in conjunction with other members of the Household. In April 1447 the Crown assigned to him and Sir Edward Hull* certain lands in Devon which had belonged to Robert Cappes, one of Gloucester’s servants; in June he and Nicholas Ellis were jointly appointed to the office of surveyor of the customs at Hull; and in August he and John Blakeney were granted the right to take two tuns of wine from the port of Ipswich at every Christmas.
In the same January, Wentworth was re-elected to the Commons. On 10 Feb. 1449, two days before the Parliament opened, the Crown granted him a 60-year lease of the castle and manor of Offton and the manors of Elmsett and Somersham, all duchy of Lancaster properties in Suffolk. At the same time, or shortly afterwards, he was constable of Offton, an office he exercised jointly with an usher of the chamber, William Cotton, with whom he likewise shared the post of constable of the duchy castle at Clitheroe, Lancashire. Six days after Parliament opened, Wentworth attended a meeting of the royal council,
Largely unaffected by the crisis of 1449-50, Wentworth was knighted in the early 1450s. By 1452, he was one of the King’s carvers, an elite group within the Household, and in April that year he and a fellow carver, Richard Tunstall†, were jointly awarded £100 for attending and serving the King.
The Parliament of the following year was the most compliant of Henry VI’s reign. Wentworth was among the courtiers returned, although not without some controversy. The sheriff of Norfolk and Suffolk, Thomas Sharneburne*, subsequently alleged that Sir William Ashton, John Howard* and many other servants of the duke of Norfolk had threatened his under sheriff, Thomas Grys, and his clerk, William Peyntor, prior to the county election in Suffolk. He claimed that they had forcibly brought Peyntor before the duke who, it was implied, had pressured him to return his nominees to the Commons. Sharneburne further alleged that on election day itself, 12 Feb. 1453, a large number of Mowbray men had come in armed force to the county court at Ipswich, where they had returned Thomas Daniell* (who held no lands in the county) and John Wingfield† (a non-resident). The election, which neither Sharneburne nor his deputy had attended, was afterwards declared invalid, and Wentworth and Gilbert Debenham I*, a Mowbray man but then temporarily estranged from the duke of Norfolk, were returned at a new election held on the following 12 Mar. There is little doubt that Mowbray had attempted to influence the election, although it is equally clear that Sharneburne, a member of the queen’s household, had been determined to return candidates who enjoyed the support of the Court.
Just as he had done during his previous Parliament, Wentworth attended at least one meeting of the King’s Council while a Member of that of 1453.
The enmity between Fastolf, a leading opponent of the de la Pole affinity in East Anglia, and Wentworth dated back several years. Wentworth was a particular thorn in the flesh for Fastolf, competing with him for the wardship of his relative, Thomas Fastolf†, and challenging his title to certain lands. His claims to these estates were opportunistic and unjust, but in making them he was perhaps partly motivated by the frustration of having to wait to come into his own inheritance. During the late 1440s he attempted to wrest the manors of Beighton in Norfolk and Bradwell in Suffolk from Sir John, who had bought them quite legitimately from Sir Hugh Fastolf, the young Thomas’s grandfather. He was assisted by two de la Pole followers, John Andrew III*, a man whom Sir John and his supporters viewed with particular opprobrium, and John Ulveston*. Having broken into Fastolf’s house and close at Beighton in April 1449, Andrew and Ulveston forged two inquisitions which declared that the manors were the rightful inheritance of Thomas.
During the quarrel, Wentworth’s claim that Beighton and Bradwell belonged to Thomas Fastolf made physical custody of the ward crucially important. Wentworth’s brother-in-law, Robert Constable*, had acquired the boy’s wardship from the King in November 1447, in spite of protests from Sir John Fastolf, who had argued that Thomas’s father had committed it to him in his will and that the ward’s mother had surrendered her son to Constable under duress.
By now, Mowbray had good reason heartily to dislike Wentworth, who had remained in the service of the dowager duchess of Suffolk following the downfall of William de la Pole and helped her to resist his claims to her manor of Stockton in south-east Norfolk.
A year later, John Paston was informed that John Andrew had an annual fee of 20s. from the manor at Nacton, indicating that Wentworth was using some of the income from the young Thomas Fastolf’s properties to reward his supporters.
The dispute over the wardship continued after Fastolf died in early November 1459. During the Parliament of that year (which opened a fortnight after Sir John’s death) Wentworth successfully petitioned to have the letters patent issued to Paston and Howes over five years earlier declared invalid.
In the meantime, whatever had happened at the first battle of St. Albans, Wentworth retained the trust of the Lancastrian Crown.
Following the renewal of civil war in the autumn of 1459, Wentworth remained loyal to the Lancastrian Crown. On 14 Nov. that year he was appointed to a second term as sheriff of Norfolk and Suffolk, just two days after his election to his last Parliament, held at Coventry. The Parliament of 1459 attainted Richard, duke of York, and his supporters and Wentworth served on several anti-Yorkist commissions established in late 1459 and early 1460. On 20 Dec. 1459 (the day Parliament dissolved) the King made him chief steward for life of the East Anglian honour of Clare, a lordship confiscated from York himself. He received one of his last grants from the Lancastrian Crown in the following March when he was awarded the wardship of Richard Mekylffyld, heir to an estate in Suffolk.
A few months later, the Yorkists regained control of the government, and by the end of 1460 the queen had raised an army in the north of England to resist them. Along with other loyal Household men, Wentworth joined her forces. He fought for the Lancastrians at the battle of Towton in March 1461 and was attainted in the first Parliament of Edward IV’s reign.
In spite of Wentworth’s execution, his son and heir, Henry, was conspicuously loyal to the new dynasty and in due course joined Edward IV’s household.
