Sixty years after William Essex’s death, the antiquary John Leland, who referred to him as ‘a politike felaw and in favor of the King’, believed that he had come from a family ‘long since knights of fame in Essex’, whose ‘glorie’ had been ‘almost extincted’ until the MP recovered its fortunes.
Once having left Coventry, Essex made his career at the Exchequer and henceforth his activities were always focused on Westminster and the city of London. Presumably after completing some training in the law, he quickly rose to prominence as an attorney in the Exchequer court of pleas, where by 1440 he had already been singled out to act for prominent individuals, such as Sir John Colshull* of Cornwall, as well as for borough officials including the bailiffs of Canterbury.
Nevertheless, Essex did not occupy either of the posts in the customs service for long; he had relinquished them by the time he was returned to the Parliament of 1449-50. In this Parliament, the only one in which he is known to have sat in the Commons, he represented Dorchester, a borough with which he had no recorded connexion. Clearly, he was in breach of the statutes with regard to residential qualifications, but it is now impossible to tell whether his name was written on the schedule accompanying the Dorset indenture by the sheriff’s officers or was not inserted until after the indenture reached Westminster. The latter conjecture is quite feasible, for more than half of the men returned by the Dorset boroughs on this occasion were, like Essex, complete outsiders to the county. Furthermore, a number of them were also employed at the Exchequer: Thomas Cross* and John Gloucester II were his fellow clerks, and Andrew Kebell* comptroller of the pipe. During the parliamentary sessions they would have been at hand in the Commons to assist the treasurer’s remembrancer Thomas Thorpe* (then sitting for Northamptonshire) when questions were raised regarding the Crown’s pressing need for subsidies and loans as English possessions in Normandy fell catastrophically to the French. Less clear is the political role they may have played in the second session, when the King’s chief minister the duke of Suffolk was impeached. The Parliament, meeting for its third session at Leicester, was dissolved in early June 1450 at the outbreak of Cade’s rebellion. Essex managed to escape the criticism aimed at many of Suffolk’s followers, proving to be more fortunate than his friend Thomas Kent, who on 4 July was indicted for plotting to put the duke’s son on the throne by marrying him to Margaret Beaufort. Essex stood bail for him, but 15 months elapsed before he secured acquittal in the King’s bench.
After the dissolution of the Parliament, in November 1450 Essex was rewarded for his commitment to serving the King and the queen with promotion to the office of King’s remembrancer (replacing the disruptive Thomas Daniell* and John Troutbeck*). This he retained until he died – a period of nigh on 30 years, and through several changes of regime.
Throughout this period of the 1440s and 1450s Essex had been much involved in the affairs of Londoners, as is clear from his regular appearances as a recipient of the goods and chattels of a number of skinners, haberdashers, dyers, fishmongers and tailors.
Despite the changes of regime during the civil war years, Essex continued to be appointed to the Middlesex bench for the rest of his life, and his reputation as a hard-working and conscientious official at the Exchequer prompted Edward IV to confirm him in office as remembrancer and led to his exemption from the Act of Resumption passed in the Parliament of 1463-5.
The Babthorp wardship was not the only one in which Essex bought an interest. In 1466 he joined Hugh atte Fenne*, another prominent Exchequer official, in paying 400 marks for the wardship and marriage of the wealthy heir Nicholas Carew (the grandson of Nicholas Carew*, the former shire knight),
It is a measure of the respect in which he was held that in the course of his career Essex had often been asked to serve as an executor for colleagues and friends. Among these were the Warwickshire lawyer Thomas Bate* (d.1459), the former chief baron of the Exchequer Peter Arderne (d.1467),
After the death of his first wife, our MP had married the daughter of a lawyer from Sussex, in a match which does not appear to have been made for material gain. On the contrary, it brought with it financial liabilities, for Elizabeth Mille had taken on the executorship of her mother’s will. Fortunately, in 1473 her brother Richard provided that she should have £140 from the family lands in order to fulfil her duties.
