Clemens’s parentage is obscure, but he may have been a son or other kinsman of Richard Clemens who in 1450 was said to hold 40s. worth of property in Cornwall, and alongside whom he witnessed a Liskeard property transaction in December 1447.
As Clemens grew in standing in his profession, and found increasingly frequent employment with a range of individuals and corporations, mostly in Cornwall,
It was during the 1440s that Clemens was drawn into the orbit of one of the leading Cornishmen of his day, the duke of Exeter’s retainer Thomas Bodulgate, an esquire of Henry VI’s household, a connexion that would shape the course of his career for much of the remainder of the reign. Clemens had perhaps first come to Bodulgate’s attention during the 1442 Parliament, when the older man had been one of the knights of the shire for Cornwall, and later that year he was employed by Bodulgate as his attorney in the court of common pleas. He would perform similar services for him on later occasions.
Occasional appointments to ad hoc commissions followed, but in the autumn of 1455 even these dried up, and Clemens’s career of office holding under the Crown remained unimpressive. It is possible that his relations with Bodulgate had cooled, for although the two men continued to share the constableship of Tintagel, by the summer of 1459 they were in open conflict. The background to their disagreement is uncertain, but it may in some way have been connected with the de Brune inheritance which was then in dispute between Bodulgate and, among other claimants, the Somerset gentleman Peter Shetford*, for Shetford headed the list of south-westerners (which also included Clemens) whose offences were submitted to the adjudication of a high-powered commission (headed by Bodulgate’s patron, the duke of Exeter) in June of that year.
Clearly, Clemens’s disaffection with the Lancastrian administration was absolute, for following the victory of the Yorkist earls at the battle of Northampton in June 1460 he rapidly rose to considerable prominence in the administration they established in Henry VI’s name. In this, he may have been assisted by the family ties he had established in the Yorkist camp through the marriage of his eldest son to the heiress of the Beaucombs of Beaucomb, who had for several generations headed the household of the father and grandfather of the earl of March’s confidant, John Dynham of Nutwell.
As an important Crown servant, as well as a prominent lawyer, Clemens’s professional services were widely sought after throughout the West Country. Apart from the towns of Liskeard, Saltash and Truro, which employed him as their steward in these years, he acted as legal counsel for the duke of Buckingham, the bishop and dean and chapter of Exeter, the priors of St. German’s and Tywardreath and the Pomeroys of Berry Pomeroy, and estate steward of Sir John Marney of Colquite.
In the event, Glyn regained his freedom and survived his ordeal. Once at liberty, he lost little time in striking back at his enemy. Throughout the late spring of 1470, so Clemens complained later that year, Glyn and his servants had lain in ambush for him, and had all but prevented him from going about his business. Yet, in October Edward IV’s exile and Henry VI’s restoration once more placed Clemens in the ascendant. On 20 Oct. his attorney, John Penlyn†, appeared in the court of common pleas, and charged Glyn, who was present attending to his duties as a filacer, with repeated threatening behaviour towards his employer, claiming the vast sum of 1,000 marks in damages.
If Clemens had been stripped of his offices in early 1470, he was evidently restored to them by the Readeption government.
Parliament assembled not long after the murder, and Glyn’s distraught widow successfully petitioned the Commons for an act of attainder against her husband’s murderer. The murdered filacer’s synonymous son, a Lincoln’s Inn lawyer, proved even more resourceful, and with the support of the King’s brother, the duke of Clarence, secured Clemens’s arrest and imprisonment in London’s Newgate gaol on 16 Nov. There he languished for two months until, probably succumbing to the conditions of the notorious prison, he died on 17 Jan. 1473.
