The early life and ancestry of this Member are obscure; and we cannot be entirely certain if he was the William Elys who served as one of Edward III’s serjeants-at-arms. The latter was employed between 1348 and 1352 on various tasks, largely concerning the purveyance and transport of victuals to the royal army in France. It is, however, interesting to note that on two separate occasions he offered property in Yorkshire as security for unpaid debts, so he may perhaps have gone on to represent the county in Parliament, albeit at a somewhat advanced age.
Perhaps through his connexion with the Everinghams (or even as a result of service in the royal household), Sir William came to the attention of Edward Ill’s younger son, Edmund of Langley, duke of York, who retained him at a fee of 40 marks a year. The date of their contract is not now known, but in February 1389 he exchanged the duke’s livery for that of his nephew, Richard II. His annuity (now assigned from the fee farm of Kingston-upon-Hull) remained the same, although his new status as a knight of the King’s body was naturally more impressive. He went bail for Sir John Drayton, then a prisoner in the Tower; and in December 1390 he managed to secure a royal pardon for a Yorkshireman found guilty of robbery. His position at Court, no less than his recently-acquired influence as a local landowner, admirably qualified him to sit in the House of Commons, although he did not live long enough to represent Yorkshire more than once. The second Parliament of 1390, of which he was a Member, was still sitting when he negotiated a lease of the parsonage of Harswell, Yorkshire, at the Exchequer, agreeing to pay an annual rent of 14s. for the tenancy. His attempts to acquire the bailiwick of Strafforth involved a far greater outlay, for the office was then occupied by John Wightloke, a serjeant of the chamber to King Richard, who would not surrender it without a handsome payment. In September 1391, Sir William promised him a rent of £10 p.a., payable for life from his manor of Fairburn, guaranteeing his offer with securities of £200 as an earnest of good faith. Richard II was happy to sanction the transfer, which received his approval in royal letters patent of the same date. Save for a dispute with one of his neighbours, which reached the York assizes in August of that year, Sir William thus had every reason to congratulate himself upon his good fortune.
