Wylne came from a family of yeomen established at Melbourne, a few miles to the south of Derby on the border between Leicestershire and Derbyshire. In the subsidy returns of 1431 his putative father, William Wylne of Melbourne, described as a yeoman, was returned as holding a free tenement in Normanton on the outskirts of Derby. This partly explains and justifies Robert’s later connexion with the borough and suggests that he was a descendant of Gervase Wylne†, MP for Derby on several occasions in the first decade of the fourteenth century.
During the late 1430s and 1440s Robert made significant gains from royal patronage. On 8 Mar. 1437 as a yeoman of the Crown he was granted 6d. a day assigned on the issues of the shrievalty of Oxfordshire and Berkshire; at the end of the year he was appointed to the duchy parkership of Stockley with its wages of 1d. a day; and in the autumn of 1438 he joined Edmund Archer in the parkership of Castle Donington (near Melbourne) in Leicestershire. This last grant is another indication of a connexion with the Stauntons for the younger Thomas was soon to be appointed constable there.
Wylne’s duties in the royal household kept him often away from his native shire not only when required in the King’s presence but on miscellaneous administrative tasks. For example, on 13 Nov. 1448 he found himself at St. Mary’s church in Nottingham on royal business: with the lawyer Thomas Chaterley*, another Derby MP, he questioned an executor of a canon of Southwell concerning a bequest. On the following 17 Feb. he was at St. Bride’s in Fleet Street, London, to take an oath regarding the same matter. His appointment in June 1452 to secure the appearance of a Norfolk chapman before the royal council is similarly to be seen as an aspect of his Household service.
In the wake of the confiscations which followed the rout of the Yorkists at Ludford Bridge, Wylne received the most substantial mark of royal favour that was to come his way: on 12 Feb. 1460 he was granted for life the office of keeper of the park of Sheriff Hutton in Yorkshire, forfeited by Richard Neville, earl of Salisbury. By this date he had been promoted within the ranks of the Household for he was then one of the gentlemen ushers of the Chamber.
Very little can be discovered about the last years of Wylne’s life, which he presumably lived out quietly in retirement at Melbourne. On 29 May 1469, described as an esquire, he witnessed a deed at King’s Newton near his home, and on 20 Jan. 1472 he again sued out a general pardon.
