A leading figure in the troubled politics of mid fifteenth-century Norwich, Henstead was a mercer who traded also as a general merchant. In common with other citizens, he used the port of Great Yarmouth for his mercantile activities, in his case exporting woollen cloth and importing a variety of commodities, including hats, vinegar, fish and paper.
In Norwich itself, Henstead was active in civic affairs by 1433, when he attested his first parliamentary election and became sheriff. While sheriff, he and his associate in that office, Robert Londesdale, arrested a Norwich chandler, Geoffrey Quyncy, for employing incorrect weights and measures. Shortly after he and Londesdale had completed their term in the shrievalty, Quyncy sued them in the Chancery, claiming that the weights and measures he used met Exchequer standards and accusing them of unlawful arrest.
At the end of the same decade, another of Wetherby’s allies, the former recorder of Norwich, John Heydon*, sued Henstead and other aldermen in the court of common pleas, claiming that they had assaulted and threatened him at the mayoral election of 1437. In July 1439 a jury, which included Chaplain and Heydon’s associate Sir Thomas Tuddenham*, found the defendants guilty of making threats although not of assault, and awarded Heydon no less than 400 marks in damages and costs. Henstead and his co-defendants afterwards sued the jurors for awarding Heydon an excessive sum, although they failed to pursue this suit to a conclusion.
The Crown did not restore Norwich’s liberties until late 1439, although in May the previous year Henstead and other citizens had journeyed to London to seek the good grace of the King and certain lords of his council. William was also one of those who met the duke of Norfolk in early 1441, to inform him that the city was ‘so desolate of everything’ that it was unable to make the King a significant loan.
At the end of the same year, Henstead wrote to an unnamed lord (probably the treasurer, Ralph, Lord Cromwell), to inform him of the citizens’ fear that Suffolk’s award might prove prejudicial to the King’s interests.
There is no evidence that Henstead played any official part in civic affairs for some four and a half years after his dismissal as mayor.
After 1450 the troubles that had afflicted Norwich in previous decades subsided and Henstead’s later years were quieter as a result. One personal concern in the early 1450s was securing the sum of £17 the city owed him for his time as an MP. He must have petitioned the Crown about his unpaid wages, since in June 1451 the King commanded the sheriffs of Norwich to ensure that he received the money due to him. The most likely reason for the non-payment of these wages is corporate insolvency, which probably also explains why the corporation asked him and other aldermen for loans (in his case six marks) towards the cost of receiving Queen Margaret when she visited Norwich in April 1453. By the end of 1456 the city, which now owed several aldermen significant amounts of money, was in debt to Henstead to the sum of £55 6s. 8d. He forswore £42 of this sum, although the corporation did not begin to repay the remaining 20 marks until over five years later.
It was also during the mid 1450s that Henstead became involved in a quarrel between the men of Yarmouth and the Cinque Ports. The Ports enjoyed certain jurisdictional rights at Yarmouth’s annual herring fair, and the dispute began at the fair of 1456, when William Stamer of Hastings took goods from a ship’s boat while fishing off the Norfolk coast. Henstead and other merchants from Norwich and Bishop’s Lynn claimed that the stolen merchandise belonged to them and was worth 2,000 marks. The provost of Yarmouth reacted by arresting the Cinque Ports’ bailiffs attending the fair, prompting the Ports to bring the matter before the chancellor. Henstead took action of his own in Easter term 1457, when he lodged an appeal for robbery and breach of the King’s peace against Stamer and other men from the Ports, including Robert Onewyn I*, one of the bailiffs whom the provost had arrested. He came to the court of King’s bench in person in the following November and successive return days, although the defendants failed to appear and proceedings for their outlawry were initiated.
Henstead remained active in the following decade, although by then he had ceased to hold any office at Norwich apart from that of j.p. The corporation still owed him money in the early 1460s, and in March 1461 the corporation agreed that he, Robert Toppe* and Gregory Draper* should receive the profits of the common quay for a year, so that they could recover the sums in which the city was indebted to them. Henstead attested the return of Norwich’s MPs to the Parliament of 1467 and he took part in discussions with the bishop of Norwich about cleaning the river Wensum in the spring of 1468. In July the following year, he helped to arrange ‘stations’ (presumably tableaux) at Norwich’s Westwick and Friars Preachers’ gates, in preparation for a visit by Edward IV’s queen.
Presumably well advanced in years when he made his will on 5 Feb. 1472, Henstead was dead by the spring of the following year.
