The Isles had lived at Sundridge since at least the reign of Edward II, probably occupying the property known as ‘Broke’s Place’,
At that date William had probably come of age. At the end of his own life his estate included the manor of Sundridge and a moiety of that of Charton (inherited from Freningham), another manor in Sundridge, called Dreyhill, a moiety of that of ‘Slobbe’ in Sevenoaks, eight named messuages and some 370 acres of land. These were said by jurors at his inquisition post mortem to be worth about £25 10s. p.a.,
Isle may have completed his training in the law by November 1432, when he was among a large group headed by John Martin, c.j.c.p. who were committed the keeping at the Exchequer of certain lands in Yalding and Brenchley in Kent which had been held by the recently deceased tenant-in-chief Thomas Enot. The presence of Henry Rowe, one of the wardens of Rochester bridge, and John Beaufitz, a leading bridge councillor, in the group suggests that the issues of this property may have been intended for the upkeep of the bridge, of which Isle’s kinsman John Freningham, had been one of the founding patrons.
In the 1440s Isle established an association with others linked with Fiennes in Kent, notably Stephen Slegge* and Robert Berde*. In 1445 he was involved in litigation in the court of common pleas over a messuage in Maidstone in which he had been enfeoffed along with Slegge and others; in February 1446 he acted with Berde in the acquisition of rents from property in the London parish of St. Nicholas Cole Abbey, and on the following 25 Nov. all three of them were present to witness a charter by which Edmund Lenthall, the nephew of the late earl of Arundel, quitclaimed the manor of Mereworth to Fiennes and his son, William.
The rebels under Cade sought to replace those false counsellors about the King who had lost Normandy and impoverished the Crown with the ‘lordys of his ryall blode’. Chief among their targets and representative of ‘all the false progeny and afynyte of the Duke of Southefolke’ was Saye who, along with his son-in-law, Cromer, was murdered in London in early July. The rebellion also had a local context and Saye’s friends and servants in Kent also found themselves accused of corruption and treachery. Cade’s third manifesto demanded justice against the ‘grete extorcioners beyng in Kent . . . that is to say, the traytours, Slegge, Crowmere, Ysele and Robert Est’.
The difficult political circumstances and disruption in Kent prompted Isle to concentrate on his legal practice in the capital. Perhaps he also had personal reasons to do so: on 2 Jan. 1451 John Bocking wrote to William Wayte ‘Ulveston is styward of þe Mydill Inne, and Isley of the Inner Inne, be cause thei wold have officz for excuse for dwellyng this tyme from her wyves’.
Within days of the accession of Edward IV Isle’s fortunes took a turn for the worse. Seemingly, his perceived his property at Sundridge to be under threat, and to pre-empt an attempt to evict him on 20 Mar. 1461 he broke the close of John Brampton there, and stole wood and other goods to the value of £20. Then, on 15 Dec., a commission headed by Lord Abergavenney was appointed to investigate alleged extortions carried out by Isle, an old associate, Robert Dreylond of Selling, and four others. Isle was summoned to answer Brampton in the court of common pleas the following Hilary term, when he thought it wise to purchase the new King’s pardon.
Before the second commission into Isle’s alleged misdoings could get underway, it was overtaken by events. In June 1463 his manor at Sundridge had been broken into and cattle stolen; further raids took place in August and September. The perpetrators, a group of his lesser neighbours and possibly his own tenants, soon went a step further. To avoid their hostility, Isle appears to have taken refuge with the vicar of Farningham, some ten miles from Sundridge, but they caught up with him. At one o’clock in the morning on 14 Dec., a gang of 80 men, led by Edward Tawke, a gentleman of Sundridge, and William Wodeward, a yeoman from nearby Bierling, murdered Isle and his servant, John Stokton, in the vicar’s chamber, leaving them decapitated.
Isle was buried at Sundridge, his tomb bearing a brass with an inscription, now lost, describing him as ‘legis peritus’.
