Thomas came from a family established at Newmarket in Suffolk, but close to its border with Cambridgeshire, of which Ralph Wykes, the sheriff of 1379-80, was a member. The latter had a son called Thomas, who in the early years of Richard II’s reign had dealings with the earl of Oxford’s uncle, Sir Aubrey de Vere (in connexion with the de Veres’ estate at nearby Dullingham). The shire knight would seem, however, to have been a different person.
Wykes was present at the shire court at Cambridge to attest the indentures of election for the Parliament of 1413 (May), and he himself was returned for the county three years later. His Membership of the Commons seemingly failed to bring him to the attention of the government, for he was never appointed to royal commissions. Following the death in September 1416 of his kinsman, John Wykes, Thomas was drawn into the struggle of John’s widow, Agnes, to retain possession of an estate in the Isle of Thanet, Kent, which her husband had acquired through his first marriage, to a member of the Kyriel family. The widow married William Goodred the elder, and it was in association with his son, William the younger, another lawyer, that Wykes was bound over in February 1419 to keep the peace towards Hugh Strauley, esquire, who was also a claimant to the disputed estate. The title of the Wykes family appears to have been proved satisfactorily for a while, for in February 1427 the property was granted out, on an Exchequer lease, for the duration of the minority of John Wykes’s son, John. Thomas provided securities for the lessees, only to take over custody himself just three months later, when he agreed to pay the Crown an annual farm of 20 marks. This transaction led to his involvement in a lawsuit four years later, when Sir Thomas Kyriel tried to gain possession of the property. In the meantime, Wykes had attended the Cambridgeshire elections to the Parliament of December 1421, and in the following May he had appeared in Chancery as a mainpernor, under penalty of £100, that a local esquire would keep the peace.
In the 1420s Wykes moved to Kent, where he settled at Nackington near Canterbury and farmed Nether Court, a manor adjacent to the one in the parish of St. Lawrence on the Isle of Thanet which he was currently disputing with Kyriel. In a will made on 27 Sept. 1425 he left his daughter, Joan, his lands in the county, together with 100 marks as her dowry, stipulating that in the event of her death without issue her heirs should be the three daughters of his kinsman, Edmund Wykes, to whom he left 20 marks each for their marriage portions. Only if all four girls died childless was his son, another Edmund (quite likely a bastard), to inherit the estate, although the latter was to receive certain moveable goods if he made no trouble over the will. Wykes’s property in Newmarket and Exning was to be sold for pious uses. He asked to be buried in St. Augustine’s abbey, Canterbury, to which he donated 20 marks. A further sum of 20 marks was to be doled out to the poor attending his funeral, while £4 was bequeathed to St. Sepulchre’s priory to pay for a window dedicated to St. Ethelbert. Wykes, who in July 1426 joined with John Deken the London grocer in offering sureties to John, duke of Bedford, for the payment of £177 in damages owed by the abbot of St. Augustine’s to certain foreign merchants, died at an unknown date between the following January (when he was discharged of his obligations) and February 1431.
