On 21 Dec. 1436 Sir William Leigh contracted his son William, as a 12-year old boy, in marriage to Isabel Bolde for the handsome portion of 350 marks.
Little is known of the early years of Leigh’s career. On 7 Nov. 1446 he offered mainprise for his kinsman, John Skelton II* in a royal lease of property in Armanthwaite, and on 21 Jan. 1449 he was among those who attested the election of Thomas Curwen* and Hugh Lowther to represent Cumberland in Parliament.
It was at about this time that Leigh contracted a second marriage that was socially, although not materially, advantageous. At some date between early 1453 and Michaelmas term 1458 he married a daughter of Lord Dacre, in whose wardship he had been, and the widow of the heir to the Yorkshire barony of Scrope of Masham.
On 13 Nov. 1459 Leigh was elected to represent Cumberland in company with (Sir) Thomas Curwen.
None the less, although Leigh escaped the most serious consequences of his active support for the defeated side, he did not regain his place in local affairs until the restoration of the Percys. Not surprisingly, he was excluded from the commission of the peace and he makes very few appearances in the records for the 1460s. In Easter term 1462 he was one of many Cumberland and Westmorland gentry against whom William Tilliol alias Colville had actions of trespass pending. These actions probably arose out of widespread resistance to Colville’s efforts to make good a claim to the estates of Sir Peter Tilliol*.
With the Percy earl restored to his proper place in northern affairs, Leigh was more active in Edward IV’s second reign than he had been in the first. In 1472 he was named to a commission of array; in 1473 he was restored to the Cumberland bench; and in the following November he was again named as sheriff. While sheriff, on 13 Aug. 1474, he was nominated as an arbiter in a dispute between John Pennington, who like him was a servant of Percy, and Sir John Huddleston, who was in the service of the new force in northern politics, Richard, duke of Gloucester. The feoffees Leigh himself chose, in the following January, for his manor of Surlingham can be interpreted as marking recognition on his part of these new political realities: Huddleston and two of his sons headed the feoffees, and they were joined by two members of the Dykes family, long connected with the Percys, and our MP’s kinsman, Robert Lowther.
From the mid-1470s advancing age meant Sir William surrendered some of his responsibilities to his eldest son, Thomas, who replaced him on the Cumberland bench in May 1483. He died a year later. Inquisitions were held in Norfolk, where his manor there was returned as in the hands of the feoffees of 1475, and Cumberland, where the jurors mentioned only his lands in Stainton, which he had given to his brother Robert for life on 4 Dec. 1460. His heir was returned as his son Thomas, who, for a mysterious reason, was said to be only a year old. The Chancery did not act on this erroneous finding for no grant of wardship was made. Thomas died in 1493 and was succeeded by Sir William’s younger son, Robert.
