Of an ancient and well-connected family, Lisle was aged about 22 when his father died in February 1429. Along with his mother he was an executor of John senior’s will, and in May he received seisin of part of his inheritance. This, consisting of estates in Hampshire, Dorset and Wiltshire, and in particular on the Isle of Wight (where the Lisles possessed at least 14 manors), was burdened with two dowagers – John’s elderly grandmother, Elizabeth, widow of Sir John Lisle† (1366-1408), who lived on until February 1435, and his mother, Margery, who retained jointure in the estate at Chute in Wiltshire and in four manors in Hampshire, besides her dower portion.
Lisle further added to his landed holdings through his first marriage, to Anne, the only child of John Botreaux, a younger son of William, Lord Botreaux (d.1391). In 1433, under the terms of a settlement made by his mother, John had come into possession of the manor of Lund on the Wold in Yorkshire, worth £20 p.a., and following the death without issue of one of his elder brothers, Sir Ralph Botreaux*, he also acquired property in Westmorland and the manor of Brixton in Devon, along with some 480 acres of land at Westlake, Bradford and elsewhere. Before his death on 25 Mar. 1444 he settled on Anne and her husband Lisle his holdings at Up Sydling in Dorset.
At the time of his first election to Parliament in 1433, at the age of about 25, Lisle had yet to serve on an ad hoc commission of local government, although his Membership of the Commons determined appointments to distribute the allowances on the subsidies granted in the second session and to help administer the oath against maintenance. He had attested the electoral returns for Hampshire at the shire court at Winchester in the previous year, and was to do so again on six more occasions, his standing in the county being quite often indicated by his place at the head of the lists of attestors.
There is no definite evidence of Lisle’s presence in England between then and June 1446. On the following 22 Dec., described as a ‘King’s knight’, he was granted in consideration of his ‘good and praiseworthy service’ the keeping of lands which pertained to the King owing to the death of Sir Stephen Popham* and the minority of three of Popham’s daughters and coheirs, together with their marriages, paying for the latter a sum to be agreed with the treasurer. Lisle had known Popham personally, and was currently a feoffee of his estates in Wiltshire and Hampshire. This caused him some problems: he was cited in a petition sent to the chancellor by Popham’s oldest daughter, Elizabeth, the wife of John Wadham, who claimed he had refused to hand over to her the manor of Fisherton, which her father had promised her; and at some point he conveyed to another of the heiresses, Alice, and her husband Humphrey Forster†, the manors of Steeple Langford and West Grimstead, without first obtaining a royal licence to do so. Lisle was also a feoffee of the Popham manors governed by entail, which passed to Sir Stephen’s cousin Sir John Popham* before returning on the latter’s childless death in 1463 to the heiresses.
During the troubled years of the late 1440s and the 1450s the Crown enlisted Lisle’s help as the Isle of Wight was threatened by invasion from France. The inhabitants of the island had suffered severely from misgovernment under the tyrannical rule of John Newport I*, and in the autumn of 1450 ‘Jenquyn’ Baker esquire was ordered to sail over to Carisbrooke casle with a small body of men to reinforce the garrison. Letters of privy seal were sent to Lisle in the following spring to check whether Baker was doing his duty as ordered: he replied, certifying that Baker was at Carisbrooke with a full quota of soldiers.
During the crises of the mid 1450s Sir John was among those on whom the government placed heavy reliance. In a letter sent by the Council in December 1455 to a number of magnates requiring them to accompany and assist the Protector, Richard, duke of York, on his journey to the south-west to restore order, Lisle headed the list of 14 ‘men of gode birth and havour’ ordered to wait on them. The defence of the Isle of Wight also continued to cause concern, and in September 1457 orders were sent to him and (Sir) Henry Bruyn* giving them sole responsibility for the safeguard of the Island and of Portchester castle.
In the course of his career Lisle had been acquainted with a number of persons of note. In 1445 he had acted as a mainpernor under pain of 100 marks for Nicholas Carew, Baron Carew;
The marriage Lisle had negotiated for his sister Elizabeth might have been intended to further extend his connexions and enhance his own standing at Henry VI’s court, for her husband, John Pury*, was closely associated with Archbishop Kemp and William de la Pole, earl of Suffolk. In 1439 he settled on the couple an estate at Crookham and Thatcham in Berkshire, including the manor of Chamberhouse, which his grandfather had acquired at the start of the century. Yet Elizabeth’s death not long afterwards meant that his links with Pury did not long endure.
Sir John himself married twice. His second wife, Isabel, was the widow of Robert Horne, who was killed at Towton fighting for Edward IV. On 30 Aug. 1461 she received a royal grant of 40 marks a year from Milton by Sittingbourne in Kent to help support herself and her three daughters, and it seems likely that she also brought to Lisle an income from other properties in that county.
