Nicholas Leybourne was from one of the leading gentry families of Westmorland, and for the last 20 years or so of his life he was the head of that family, yet his long career is only very sporadically documented. In one sense he lived his career in reverse: it was one of diminishing rather than mounting activity and distinction. As a very young man, he joined the retinue of Sir John Neville, son and heir-apparent of Ralph, earl of Westmorland, to fight in Henry V’s campaign of 1417.
Yet this expectation was not to be realized. After heading the jurors at the inquisition post mortem of John, duke of Bedford, at Kendal on 4 Nov. 1437, he entered a period of virtual retirement that did not end with his father’s death in the early 1440s.
The records provide occasional glimpses of Leybourne’s private activities. His readiness to cross swords with two of the minor local peerage implies that he had a proper sense of his family’s standing. In 1442 George Neville, Lord Latimer, sued him for close-breaking and depasturing grass worth as much as £40 at Heversham, and in 1444 he brought actions against him and Sir Thomas Strickland for debts of £21 13s. 4d. each. A decade later Leybourne was in dispute with Ralph, Lord Greystoke, who, in 1456, secured a writ of outlawry against him for the alleged abduction of his ward, William, grandson and heir of William Laton*.
The few other surviving references to Leybourne show him in a more natural social milieu. On 9 Nov. 1447, within months of making his daughter’s marriage, he was one of the leading gentry of the shire who gathered to witness an award made by (Sir) Thomas Haryngton I* in the dispute between the Threlkelds and Thornburghs. More tantalisingly, a few months later he joined Sir John Pennington* and Henry Bellingham, in entering into mutual bonds in £200 to (Sir) Thomas Parr*, Sir Richard Musgrave*, Sir Thomas Strickland and John Broughton*, bonds then delivered to Haryngton. This looks like an arrangement to abide arbitration, the bonds delivered to Haryngton as escrows pending the arbiters’ award. Unfortunately, no evidence has been found to provide further illumination, yet, from a later perspective, it is interesting to find Leybourne acting as an apparent ally of Pennington and Bellingham, adherents of Percy and Lancaster.
This did not, however, betoken any sustained period of activity. Leybourne again disappears from the commissions, perhaps, on this occasion, because of death. He was succeeded by his son James, but it was not until this James’s grandson, another James†, inherited the family estates in 1510 that the lord of Cunswick resumed his proper place in local affairs. In the interim, however, Robert Leybourne, perhaps our MP’s grandson, made a successful ecclesiastical career, serving as bishop of Carlisle between 1504 and his death in 1507.
