Although we know him to have been the son of Geoffrey Barkworth of Terrington, and to have changed his name to that of his place of birth, little direct evidence survives about this MP’s early life. One of his kinsmen (who was also his namesake) took holy orders, and, in 1374, agreed to act for him as a trustee of the manor of Aspley Guise. The latter may almost certainly be identified with William Terrington, a clerk of the privy seal and distinguished notary, who held office from 1350 to 1370, being duly rewarded with a variety of lucrative prebends and canonries. Another William Terrington subsequently prospered in the service of Richard II, and even though we cannot now establish what relationship—if any—existed between him and the shire knight, the possibility of some family connexion should not be ignored.
The problem of recovering the land which Joan had received as dower from her first husband, Robert Fitzwith, meanwhile proved far more serious. Her rightful third of the manors of Bubbenhall and Shotteswell in Warwickshire and Wigginton, Weston and Ardley in Oxfordshire had been seized in the early 1360s by her stepdaughter’s husband, Sir John Beauchamp† of Holt, a powerful and tenacious adversary who claimed that she had forfeited her title to the estate by deserting Fitzwith to live in adultery with one Roger Careswelle at St. Thomas’s hospital in Southwark. Although highly implausible, her own version of this escapade was accepted in court, and in the autumn of 1369 she obtained formal restitution of the property. Beauchamp later agreed to pay her an annuity of £20 in return for the land itself, and when he fell victim to the Merciless Parliament of 1388 this arrangement was upheld. Joan’s difficulties were not, however, at an end, for before his death Beauchamp had granted a life tenancy of the manors of Shotteswell and Bubbenhall to John Catesby, who categorically refused to honour his commitment to pay part of the pension. Once again, Terrington and his wife went to law, winning their suit against Catesby in 1391 after considerable delays and prevarications. Much later, in April 1405, they were obliged to petition Henry IV for a special assize to be held after their eviction from the three Oxfordshire manors, but nothing seems to have disturbed their tenure of the property between these two dates.
While still a comparatively young man, Terrington had taken part in various campaigns overseas, serving in the retinue of Humphrey, earl of Hereford. He first appears to have gone abroad in July 1366, when he obtained royal letters patent permitting him to appoint two attorneys to supervise his affairs at home. Together with his friend and future parliamentary colleague, Ralph Walton, he fought under Hereford’s banner on two more expeditions, one of which, in the summer of 1371, resulted in a naval engagement with the French.
Terrington drew up his will on 22 Dec. 1408, and died at some point over the next six months. He wished to be buried in a side chapel in the parish church of Aspley Guise, where his tomb, with its fine panelled tracery, still stands. He had by then married his second wife, Anne, to whom he left the residue of his goods, and to whom, along with William Lawnsleyn, the family chaplain, fell the task of executing his will. He fathered at least one child, a daughter named Ellen, about whom little else is known.
