Gernet’s antecedents are uncertain. It is possible that he was a descendant of the Gernets of Halton in north Lancashire, a prominent family whose estates had passed by marriage to the baronial family of Dacre in about 1300. The Gernets, who established themselves in the first half of the fourteenth century at Rainhill near Prescot in the south Lancashire hundred of West Derby, were probably a junior branch of this family, and it may be that our MP was from Rainhill.
The other references to Gernet in these early years of his career are typical of those relating to local lawyers. On 12 Sept. 1418 he was present in the chapter house of the abbey of St. Werburgh, Chester, when Thomas Langley, bishop of Durham, paid 800 marks for the farm of the abbey’s Derbyshire properties; on 29 Mar. 1420 he witnessed the contract for the marriage of Thomas, son and heir of William Assheton*, and Ellen, daughter of Thomas Urswyk I*; and on 12 June 1421 he was named by Sir Richard Molyneux of Sefton to act as an attorney in a conveyance.
Gernet’s marriage is to be dated to this early part of his career, and provides another indication of his standing as a rising local lawyer. His wife was from a knightly family resident at Ashton-in-Makerfield, only a few miles from Rainhill. The match was, from his point of view, more important socially than materially, but she seems to have brought him some property. Her first husband, from a county family of middling rank, died in the lifetime of his father so she had no dower interest in the lands of the Langtons of Hindley (also near Rainhill), but she had no doubt benefited from a jointure settlement. The precise date of their marriage is unknown. Her son by her first marriage, Peter Langton, was said to be aged 24 on the death of his paternal grandfather in 1443, implying that the marriage took place after 1419. It had, however, been made by 30 May 1422 when our MP ‘and his present wife’ sued out a papal indult to have a portable altar.
In the 1430s Gernet’s career took an unexpected turn for which no obvious explanation suggests itself. In 1431 he began to play the sort of role in county administration that might be expected of a lawyer of his seniority. On 1 Jan. he was elected to represent Lancashire in Parliament, and in the months after the conclusion of the assembly he was named to three ad hoc commissions in the county, including one to take the musters of the force Sir Thomas Stanley, was about to take to Ireland as the new lieutenant there.
Once he had moved to Kent, Gernet came quickly to play a significant part in its affairs. The first indication of his involvement there was his appointment to the quorum of its bench in 1433, and in the following year he was named on the Kent list of those to be sworn to the peace.
Gernet augmented his status there by establishing some significant local connexions. By far the most important of these was with Humphrey Stafford, earl of Stafford, who as lord of Tonbridge had extensive interests in Kent. In March 1441 the earl granted him an annuity of five marks, which was paid until after 1446 but discontinued before 1450 (probably because Gernet was then no longer active in the county).
In the early 1440s Gernet left Kent with the same suddenness as he had appeared there. By a final concord levied in Easter term 1443 he alienated all his lands there to Hugh Stanlowe, and he was removed from the bench in the following June. This disengagement, not surprisingly, coincided with a period of renewed administrative activity in his native county. The Lancashire bench was reissued in August 1442 with the sole purpose of restoring him (he was the only change from the commission issued six months before).
Soon after returning to Lancashire, Gernet, as if to mark that return, contracted his daughter Joan in marriage. In August 1446 he paid a respectable portion of 110 marks to secure the hand of Adam, son of William Lever (d.1447) of Great Lever, some 20 miles from Rainhill and only a few miles from Hindley. This soon led him into dispute with his son-in-law’s paternal uncle, Henry Lever. Its settlement, by an award returned on 28 Jan. 1448, had a certain incongruity in the discordance between the apparent triviality of the point at issue, a rent of 25s., and the high standing of the six arbiters, headed by two local knights, Sir John Pilkington and Sir Geoffrey Massy. Their award, sealed in the presence of many ‘Gentiles’, was that Gernet should make Henry sure of a rent of 16s. 8d. until Adam reached the age of 14.
Gernet had been conspicuous by his absence from the litigants at the Lancashire assizes during his sojourn in Kent. On his return he brought several actions that give some indication, albeit rather imprecise ones, of his landed interests. Some of these relate to property at Hindley, the home of his first wife’s husband, and its near neighbourhood, and there is little doubt that he held this property in her right. At the Lent assizes of 1446 he sued the mayor and community of Wigan for £14 as an arrears of a rent of £2, suggesting that he had property in that borough; three years later he had an action of waste pending against a widow in respect of property at nearby Westleigh and Abram demised to her for term of years; and in 1451 he sued three husbandmen for close-breaking and depasturing at Hindley itself.
Little is recorded of the last years of Gernet’s long career beyond routine involvement in administrative affairs. He was tirelessly active as a j.p. In the last three months of 1446, for example, he sat at Bolton, Wigan, Preston, Ashton-under-Lyne and Prescot, and it is probable that he routinely attended the sessions held in the south of the county. In May 1451 he sat as a commissioner at Chorley and Manchester to assess contributions to the subsidy voted in the Parliament of November 1449.
