Robert was mentioned in 1423, as the son of the Yorkshire knight Sir John Langton, in the will of a family friend, Robert Wycliffe, chancellor and receiver to the bishop of Durham, who left him a bed of red worsted, embroidered with Wycliffe’s arms.
In the early part of his career, Robert followed his brother Henry into the service of both the Mowbray dukes of Norfolk and the Crown, and this service took him away from Yorkshire to pursue his fortunes in the far south of England. This move was made concrete in 1441 by his appointment by the 3rd duke of Norfolk as constable of Bramber castle in Sussex, a post which earned him a fee of as much as 20 marks p.a. That the appointment was for term of his life indicates that he was then no newcomer to the duke’s affinity. Yet he was also retained by Henry VI, and it was as ‘King’s esquire’ that in November 1446 he was granted a lease of 60 acres of land called ‘the port of Hulkesmouth’ at Shoreham, just down-river from Bramber. The lease was to last for as long as 40 years.
In the spring of 1453 Langton was in trouble: the sheriff of Sussex was instructed to put him in exigent for a breach of the peace. He prudently obtained a royal pardon on 5 July for any trespasses or other offences. While the cause of his difficulties is uncertain, a year later he was fined two marks in respect of a trespass against one Henry Compton, in which Compton was awarded damages of £24 6s. 8d. in the King’s bench.
The background to Langton’s election to Parliament in 1455 for the distant borough of Tavistock in Devon remains a mystery. He had no known connexion either with the borough or its lord, Tavistock abbey, or even with the county. Perhaps the political circumstances of the summoning of the Parliament lay behind it. Following the victory of the Yorkists at the battle of St. Albans the duke of Norfolk, as Richard of York’s ally, sought to engineer the return of members of his affinity to the Commons. His success at the elections for Norfolk and Suffolk is clear enough, but since returns for Sussex and Surrey have not survived, it is impossible to ascertain whether, as on other occasions, Mowbray retainers took some of the borough seats in those counties. If Langton had originally hoped to be elected at Bramber, on Mowbray territory and within his own sphere of influence, we do not know which other candidate defeated him there. After sitting in the Commons, Langton continued to make Sussex the focus of his interests, remaining constable of Bramber castle for at least 20 years more.
In 1462 Langton had been among those commissioned to arrest and bring before the King’s Council certain persons who had been ‘wandering about’ Surrey and Sussex with masked and painted faces, and had broken into parks, warrens and closes and wounded and killed the keepers.
It looks as if Langton ceased to be constable of Bramber on the death of the fourth duke of Norfolk, for the receivers’ accounts for the former Mowbray estates for 1476-7 (by which date they had come into the possession of Norfolk’s son-in-law the young Duke Richard of York), while referring to him as farmer of certain lands within the lordship of Bramber did not list him among those still receiving fees by grant of the Mowbrays. However, Henry Langton, a kinsman of his (probably his nephew), one of the yeomen of the King’s pantry, was made porter of the castle by royal grant in January 1477.
Despite his interests in Sussex, Langton himself had married a woman with property in London, in this respect, as in others, following the example of his brother Henry. This marriage had taken place by the autumn of 1462, when his wife, Dorothy Wakefield, was referred to by her married name. She was then in possession of a tenement in Lombard Street.
