There is little doubt that Sergeant, a servant of Sir Walter Hungerford†, Lord Hungerford, owed his election to three consecutive Parliaments to his patron, the chief manorial lord at Chippenham. Of unknown background, he may well have originated from outside Wiltshire. It appears that he resided in south-east England in the late 1420s, for Walter Sergeant of Kent stood surety at the Exchequer when in July 1429 the Crown granted the farm of the subsidy and alnage of cloth in Wiltshire and Salisbury to Edward Palling.
Possibly Sergeant was himself a lawyer. He participated in settlements on behalf of Lord Hungerford in 1429 and 1430, in the role of an attorney to deliver seisin of various manors and other lordships at Chippenham and elsewhere in Wiltshire to the peer. Although his involvement in such transactions does not prove that he was a member of the legal profession it is worth noting that he also acted in the same capacity alongside Walter Styrope*, who certainly was, when Lord Hungerford purchased the Wiltshire manor of Corton in 1434. In the same decade, Sergeant served Hungerford as a witness and a messenger at the Exchequer, and he was associated with his patron in 1436, as a feoffee of the will of the Devon esquire, John Cheyne of Pinhoe.
The Hungerford link must have helped Sergeant to secure grants from the Crown. In November 1429 he and a monk, Robert Wyse, gained the keeping of the alien priory of Stogursey in Somerset, for a term of 30 years at a farm of £25 6s. 8d. p.a., and in the following May he and John Spencer III* were granted the wardship and marriage of Walter Wothe*, heir to estates in that county and Dorset.
In the following year William Sergeant, almost certainly the MP’s relative, drew up his last testament, although Walter does not feature in this document, dated 20 July 1436. Evidently from Heytesbury, one of Lord Hungerford’s main places of residence, William requested burial in the parish church there, and he bequeathed money to members of Hungerford’s household and to his son, Robert Hungerford. Notwithstanding William’s Heytesbury connexion, the testament also shows that he had links with Kent, London and Derbyshire. He (and perhaps, therefore, the MP) may have originated from the latter county, since he left 6s. 8d. to a chapel in Chesterfield, a gift intended for the good of his forebears’ souls. There is, however, no last will attached to the testament, meaning that nothing is known about any lands that he may have held in Wiltshire or elsewhere. He was reasonably well to do, since he had several servants and established a seven-year chantry in Heytesbury church, although his testament does not reveal his social rank or indicate whether he followed any particular profession or trade. Among those named in the testament are his wife Iseult, his brothers William and Thomas Sergeant and John Sergeant, a monk. His executors included the London fishmonger John Fairefold and the Hungerford follower Walter Bergh*, and he asked Lord Hungerford to supervise their work. Should the peer decline that role, he requested that the recently knighted (Sir) John Paulet*, a member of the Hungerford circle, should take it on. William Sergeant was no longer alive by 24 Apr. 1437, the testament’s date of probate.
