A draper by trade, although sometimes known as a ‘yeoman’, Blakpoll is likely to have had commercial dealings with London. Many of his fellow burgesses possessed links with the City, and he himself acted as a trustee for a draper from the City in the mid 1440s.
By the late 1420s, Blakpoll featured in the court rolls of Bassetsbury, the manor that encompassed most of the borough of Chipping Wycombe, which record that he incurred amercements for keeping a ruinous tenement and committing other minor misdemeanours. At this date Bassetsbury was part of the dower estates of Henry V’s widow, Queen Katherine, but it reverted to the duchy of Lancaster after her death in January 1437. By Michaelmas 1438 Blakpoll had become its bailiff, an office which he held for many years, and for which he received an annual stipend of 40s.
As a leading resident and office-holder at Wycombe, Blakpoll was regularly party to property transactions in the town.
Blakpoll also acquired the farm of the rectory of All Saints, the parish church at Wycombe. The circumstances in which it came into his hands (at some stage in the late1430s or early 1440s) proved controversial, since they led to litigation in the Chancery. The plaintiff was William Heryng, who asserted that he, and not Blakpoll, should have had the rectory. Heryng claimed that he had agreed to lease it from its patron, the abbess of Godstow priory, Oxfordshire, for an annual rent of £18, but had not proceeded with this arrangement after Blakpoll had promised to secure a joint lease for them both at a lower rent of £16 p.a. In spite of his promise, Blakpoll had then visited the abbess, told her that his prospective partner was no longer interested in the property and secured a new lease for himself alone. Heryng’s bill is the only document relating to this case to have survived, and there is no way of knowing if Blakpoll really was guilty of sharp practice or whether he was obliged to give up the parsonage.
Early in the following decade Blakpoll was a witness in a Chancery suit initiated by his fellow burgess, John Welsbourne II*. Acting in his capacity as the executor of Margaret, widow of John Hill II*, Welsbourne brought his bill against Walter Colard* and the priest Thomas Skaryngton, alleging that they had refused to make a release of properties which Margaret had conveyed to them in trust. In due course the court commissioned the abbot of Thame and the judge Robert Danvers* to examine local witnesses and the examinations were held in Danvers’ presence at Wycombe on 5 Sept. 1461. The MP and six other witnesses, comprising ‘the saddyst and wurshypfullest men’ of the borough, supported Welsbourne’s claims, and a few weeks later the court decreed that Colard and Skaryngton should make the desired release.
In the spring of 1462, Blakpoll obtained a royal pardon. This described him as John Blakpoll senior, to distinguish him from a younger namesake, and as bailiff of Bassetsbury.
