The fact that Thomas named his illegitimate son Gilbert may suggest a relationship with Sir Gilbert Haydock, the Lancashire knight of the late fourteenth century, especially as no Hampshire origins for him have been discovered. It is likely that he was the Thomas Haydock appointed a commissioner for levying debts owing to the Crown in Cheshire in 1425, and to conduct inquiries in the same region of the north-west three years later. Trained as a lawyer, he was probably practising in the central courts by August 1426, when, in association with two Chancery officials and styled ‘gentleman’, he received from a London tailor a ‘gift’ of his goods and chattels.
Haydock purchased property in the locality piecemeal. In 1433 he and certain colleagues from Winchester College (apparently acting as his feoffees) acquired tenements and messuages in Rotherwick, Mattingley and Hartley Wintney from George Denton, the son and heir of a London mercer, who released him from all legal actions. Haydock later sued in Chancery for the return of a chest of muniments relating to the estate.
Haydock’s position as steward of Winchester College necessitated his involvement in numerous transactions as the college increased its landed holdings, and led to close dealings with its warden, Robert Thurbern, successive bursars and the fellows. While completing certain of these transactions at the time of his only Parliament in 1442 he became acquainted with Henry VI’s secretary, the Wykhamist Thomas Bekynton. Both men were feoffees of the manor of Fernhill and a moiety of that of Allington, which in 1445, with licence from the King and from Richard Neville, earl of Salisbury, they granted in frank almoin to the college to find vesture for the choristers and to meet other charges in accordance with the will of the former steward, John Fromond (d.1420) of Sparsholt. Bekynton agreed to act as a feoffee of Greywell on Haydock’s behalf in 1444, as also did Master William Waynflete, the former headmaster of Winchester College, who was then provost of the King’s foundation at Eton. Haydock’s dealings with Bekynton and Waynflete continued throughout the 1440s and after the promotion of the former as bishop of Bath and Wells and the latter as bishop of Winchester.
Besides his employment by the Crown as a j.p., Haydock was regularly appointed to ad hoc local commissions (frequently as one of the quorum), and from 1437 until his death he served as steward of the royal lordship of Odiham. His legal expertise was also valued when it came to settling intransigent disputes. Often chosen as an arbiter, in 1431 he had mediated in a quarrel between Sir Henry Hussey* and the abbot of Durford (Sussex) regarding title to a heath next to the abbey and rights to hold a fair; and in 1434 he was asked by the prior of St. Swithun’s, Winchester, to arbitrate in his suit against the authorities at Southampton over the imposition of tolls, a matter which was not easily resolved and required Haydock’s attention for more than three years. Further from home, he was ‘indifferently chosen’ to help resolve a dispute over land in North and South Mimms on the border of Hertfordshire and Middlesex in 1441, and he was one of a body of ten men, headed by (Sir) John Lisle II*, who in 1447 ruled on a partition of land in Kingsclere between William Warbleton* and William Fauconer.
Naturally enough, Haydock was often called upon to be a feoffee, performing this task for John Feriby*, the controller of the Household, and his wife the heiress Margery Berners, with respect to her manor of West Horsley in Surrey,
A final concord of 1448 may throw some light on Haydock’s family. Four messuages and land at Charlton in Dorset were settled on Walter Panter and his wife Alice for term of their lives, rendering Haydock £1 a year, with remainder to John Grey and Alice his wife and the latter’s issue, the premises to revert to the lawyer and his heirs in default of Alice Grey’s line. It may be that the latter was one of Haydock’s daughters, to each of whom he left 100 marks for her marriage.
