Waterton’s father had a very distinguished career in the service of the house of Lancaster. In the 1390s he was steward, constable and master forester of the duchy honour of Pontefract, and he was among the first to rally to Henry of Bolingbroke in the campaign that resulted in Richard II’s deposition. On close personal terms with the new King, he was appointed as master of the King’s horse in 1399 and was later, albeit only briefly, chief steward of the north parts of the duchy.
Robert the father died on 17 Jan. 1425, when, according to the inquisitions taken soon after, our MP was still five years short of his majority. These inquisitions concerned themselves only with the lands the father had held in right of his first wife, to which his stepson, Robert Elys, was heir.
Waterton’s early knighthood was justified by his wealth. Aside from the valuable manors at Gosberton and Methley and the less valuable manor at Fangfoss, he also inherited from his father the manors of Halton and Barlow (in Brayton) in the West Riding, Waterton in north Lincolnshire and some scattered properties centred around Clarborough in north Nottinghamshire.
The first part of Waterton’s career followed the predictable course of a man of such wealth. As if to justify his recent knighthood, he participated in the coronation expedition, probably crossing to France in May 1430, but this is the only evidence that he undertook military service.
Soon after, Waterton began the administrative career typical of one of the greater gentry. He was named to his first ad hoc commission of local government in July 1434; on 12 Sept. 1435 he was elected to represent his native county in Parliament in company with Gascoigne; and in the following year he was added to the West Riding bench.
Waterton’s affairs continued to prosper in the first years of the new decade. On 2 Jan. 1442 he was appointed feodary of the honour of Pontefract for life, and six days later he had a pardon of account as sheriff in £150 in recognition of his expenses in supporting the duchy tenants at Knaresborough in their dispute with John Kemp, archbishop of York.
It is impossible to say what brought about this reversal in Sir Robert’s fortunes. Debt may have been a contributory factor. He certainly owed money to the Crown, and in the mid 1440s several pleas of account were pending against him in the Exchequer. These difficulties seem to have been resolved in his favour. On 9 July 1446 he sued out a privy seal writ ordering the Exchequer to allow him to appear by attorney (notwithstanding the course of the Exchequer) to answer these pleas; and he immediately appeared to plead a pardon granted to him in the previous December against the Crown’s claim that he account for an alien subsidy collected during his shrievalty.
Although, however, there is evidence that Waterton was in debt, this can serve as no more than a partial explanation for so complete a reversal of fortune. A more attractive, but admittedly speculative, explanation is some sort of mental or physical collapse. A feoffment made on 16 July 1446, a few days after he had pleaded his pardon in the Exchequer, is suggestive here. In the previous April, at the time of the sale of Fangfoss, he had placed the bulk of his lands in the hands of feoffees closely associated with himself, headed by his brother-in-law, Lord Welles, and including his kinsman, Richard Waterton.
From the late 1440s Waterton almost disappears from the records. His administrative career effectively ended. In 1447 he was replaced as feodary and armourer in the honour of Pontefract and as alnager in Yorkshire,
Very little is known of the last years of Waterton’s life. On 12 Feb. 1465 he sued out a general pardon. More interestingly, on 1 Aug. 1466 he entered into an agreement with his nephew and coheir-presumptive, Richard, Lord Welles and Willoughby, charging his lands in Yorkshire with an annual payment of 100 marks to Welles in discharge of a debt contained in 27 obligations.
