A lawyer, Clopton was probably a relative of the Richard Clopton who attested the election of Buckinghamshire’s knights of the shire to the Parliaments of November 1414, May and December 1421 and 1423. Although never a significant landowner, he was described as a ‘donsel’ (young gentleman) in 1428 (in a papal indult licensing him to keep a portable altar) and he was accorded the style of ‘esquire’ in later years.
Clopton first appears in records of Henry V’s reign, holding office at Windsor and participating in conveyances of property in Buckinghamshire and elsewhere in the Thames valley. Among the others involved in these transactions were William Whaplode* and Richard Wyot*, almost certainly fellow lawyers.
Clopton’s formal return to Parliament as a burgess for Wycombe occurred just a day earlier, so it is possible that he was not actually present at the drawing up of the election indenture. No doubt, the electors appreciated the advantages of having an able and well-connected lawyer to represent them in the Commons, whatever his property interests in the borough at this date. Clopton’s abilities and connexions must also have helped him to become bailiff of the estates that Henry IV’s widow held in Bedfordshire and Buckinghamshire, an office in which he was certainly serving just over two years after leaving Parliament. There is no evidence that he took part in any parliamentary election at Wycombe after sitting in the Commons, although he did attest the return of the knights of the shire for Buckinghamshire on at least two occasions, including the controversial election of 1429. At a county court held at Aylesbury on 31 Aug. that year, he was among those who witnessed the return of John Hampden II* and Andrew Sperlyng* to the Parliament called for the following 22 Sept. Yet the sheriff, Sir Thomas Waweton*, sent into Chancery a false indenture recording that Sir John Cheyne I* and Walter Strickland I* were the men elected. A judicial commission subsequently established that the election of Hampden and Sperlyng should have held good, although by then the Parliament was over.
By this period, Clopton had entered the service of Sir William Moleyns, presumably through the good offices of his friend Richard Wyot, a Moleyns feoffee. Sir William, an important landowner in the Thames valley, appointed Clopton the steward of his estates, an office previously held by William Wyot, probably Richard’s brother.
A few years before Clopton acquired Addington, the King granted the marriage of the infant Eleanor Moleyns to the influential Thomas Chaucer*.
If ill health had prompted Clopton to obtain his exemption, it did not prevent him from living to an advanced age. Party to the settlement of the former Giffard manor of Somerton on William Aston and his wife and their heirs in August 1465,
