Nothing is now known about this Member’s family background save for the fact that one of his immediate ancestors evidently purchased the manor of Broughtons in Offord Darcy at some point during the early 14th century. Although not specifically described as such, Waryn may well have been a lawyer, since most of the evidence which has survived to illuminate his career concerns his involvement in the affairs of various local landowners. Despite an attempt to remove him from office in 1372 on the ground that he lacked the necessary qualifications, his appointment as coroner of Huntingdonshire certainly suggests a legal training of sorts; so too does his period of service on the county bench, and his appearance among the justices of assize chosen in 1381 by the abbot of Ramsey to hear pleas of the Crown within his liberty. Throughout his life, Waryn was active as a feoffee-to-uses for his friends and neighbours, among whom were several members of the influential Styuecle family, whose estates he held in trust for many years. He was particularly close to John Styuecle, being a party with him in December 1391 to the endowment of Sawtry abbey.
Waryn’s circle did, however, include a number of distinguished laymen, such as Sir Thomas Dengaine (d.1367), who made him a trustee of his estates in Huntingdonshire and Hertfordshire, and also, in August 1364, entrusted him with the task of supervising his affairs in England while he was abroad. Another of Waryn’s friends was the distinguished soldier, Sir William Moigne, for whom he witnessed several deeds. Together with Robert Lovetot, he was one of the securities named by Moigne during the complex financial transactions which led, in 1391, to the latter’s purchase of the manor of Sawtry Beaumes (Huntingdonshire), although both men were shrewd enough to obtain substantial guarantees from the knight to cover their own pledges.
In contrast to his busy public career, the more personal side of Waryn’s life is sparsely documented. From 1364 onwards, if not before, he lived at Offord Darcy; and at some point over the next 11 years he acquired an interest in other holdings in the nearby villages of Grafham and Hail Weston, which he and his wife then settled upon feoffees. He was later confirmed in possession of his manor of Broughtons, but there is no evidence to suggest that he was tempted to follow the example of his friends and speculate in the land market himself. Although he appears to have been so ill in 1379 that the sheriff of Huntingdonshire received orders to replace him as coroner, his indisposition did not permanently damage his career, and he retained the post for another 12 years, if not longer. He must have been in his late 60s at least, when, in July 1407, similar orders were issued for his removal from the post of verderer of the royal forests of Weybridge and Sapley, this time on the dual grounds that he was both too aged and too sick to discharge his duties effectively. Even so, he was still alive in December 1414, the date of a grant made to him and a clerk named William Weston by Henry V. The two men were to farm the temporalities of the nunnery at Stowe, although it is not known if Waryn lived long enough to enjoy the profits of this award. He may have been the father or uncle of Henry Waryn, who represented Huntingdonshire in the Parliament of March 1416, but we cannot be certain about this.
