More may be added to the earlier biography.
Vernon was born at his mother’s manor of Stackpole on the south Pembrokeshire coast.
As noted in the earlier biography, Vernon’s wardship was granted by the Crown to Sir Roger Leche†. Ward and guardian appear to have been on poor terms. According to an indictment laid before royal commissioners of inquiry in June 1414, the young Vernon, when only 15 years old, had gathered 100 men at Haddon because he feared that Leche intended to kill him.
Vernon’s connexions with men of higher rank were extensive. In the summer of 1417 he mustered in the retinue of John Mowbray, earl of Norfolk, and it was his service in the first part of the ensuing campaign that earned him his knighthood.
Much more important to Vernon, however, was his later connexion with a lord of greater political weight. His friendship with Ralph, Lord Cromwell, may have been closer than the earlier biography allows. On New Year’s Day 1448 he was present at Cromwell’s new manor house at South Wingfield to hear an oath by Richard Willoughby* that he would not impede the performance of his father’s will. Earlier, in 1437, he and his friend, Sir John Cockayne*, had joined Cromwell in receiving a quitclaim from Elizabeth Swillington of her right in the disputed Heriz inheritance.
Vernon was ready to exploit his offices and influence in the furthering of his own private quarrels. As mentioned in the earlier biography, his alleged extortions as steward of the High Peak provoked a complaint to the royal council in 1440, and there can be no doubt that his great influence could be an impediment to justice in his home county. One victim was Nicholas Fynderne of Findern, who, in the late 1430s, complained to the chancellor that Vernon had disseised him of property in Willington and then employed his ‘gret rule’ over the county’s jurors to obtain a verdict destructive of his title.
Vernon’s power began to wane in the later years of his life, and there are early indications of the problems that were to dog the career of his son and eventual heir, William. Perhaps the most threatening development was the claim of Sir Richard’s erstwhile friend, Sir William Ferrers of Chartley, to the important manor of Tong in Shropshire, which had descended to our MP from his great-uncle, Sir Fulk Pembridge†. Ferrers’s claim lay through his own mother, Ellen, grand-daughter and coheir of Sir Thomas Birmingham†, and was based on an entail of the early 1320s. In February 1450, with a trial pending at common law, their rival claims went to the arbitration of Sir John Talbot and Ralph, Lord Sudeley, who confirmed Vernon’s title, but acknowledged that the rival claim was not without merit by awarding Ferrers £60 in compensation. Nor was this the end of the matter. Indeed, Ferrers’s death in the following June may have intensified rather than diminished the threat, for his daughter and heiress, Anne, was the wife of the young and vigorous Walter Devereux II*, a servant of the duke of York. Death saved our MP from further trouble, but the Devereux claim was to pose serious difficulties for his son and heir. Ominously, in our MP’s Shropshire inquisition post mortem, the jury returned that he had Tong ‘per intrusionem’ to the disseisin of the heirs in tail, Anne Devereux and her kinsman, Richard, son and heir of George Longville†.
Other legal difficulties troubled Sir Richard’s last years. At the assizes at Stafford on 23 July 1451, a month before his death, damages of £100 were won against him by two prominent lawyers, Thomas Lyttleton and William Burley I*, who claimed the manor of Kibblestone as lessees of Sir William Trussell†. This was an important reverse in his attempt to make good his groundless claim to the lands of Margaret Trussell, who had been the wife of his paternal great-uncle, Sir Fulk Pembridge. It made a mockery of the verdict and damages (absurdly assessed at £2,080) Sir Richard had won against Sir William, seemingly by the bribery of the jury, at an assize of novel disseisin in September 1448.
Legal difficulties were matched by financial ones arising out of Vernon’s tenure of the treasurership of Calais. The revenues of the town made only a limited contribution to the costs of its defence and Exchequer advances were inadequate to cover the shortfall. His six years in the office left him with an accounting deficit of over £17,000 and his heir and executors with a considerable problem.
In happier times Vernon’s great wealth had enabled him to contract a series of advantageous marriages for his younger sons. One of these matches has previously escaped notice: in the 1440s Edmund Vernon married his father’s ward, Joan, the heiress of both her father, William Hondisacre alias Frodesley of Handsacre in Staffordshire, and her mother, Margaret, daughter and coheiress of Sir Robert Mavesyn (d.1403) of Mavesyn Ridware in Staffordshire. Sir Richard’s daughter, Elizabeth, married the King’s attorney-general, John Vampage*, to whom he mortgaged his manor of Aylestone (Leicestershire) in 1447.
Vernon’s wealth was also manifest in an extensive building programme at Haddon Hall and the remodelling of the parish church.
