Uffenham’s origins are obscure, although he is known to have been living in Wilton by the late 1430s, and to have held property in the town, in South Street, by 1443, when he settled it on William Lok and his wife. Yet his place of residence was then given as Heytesbury.
Presumably, these interests in land had been accumulated by investing the profits of a successful career as a lawyer. Uffenham’s election for Old Sarum in 1433 came at the beginning of this career, and probably owed something to his choice of profession. His links with nearby Wilton are regularly documented from then on. In 1435 he was employed by John Whithorne*, a veteran of 11 Parliaments for Wilton, to render his account at the Exchequer as bailiff of the Wiltshire liberties of the bishop of Winchester, and at the elections held at the county court at Wilton for the Parliament of 1437 he stood surety for John Mundy*, one of those returned for the borough.
Meanwhile, in 1445 Uffenham had taken over from a fellow lawyer, John Giles*, the post of clerk of the peace in the county, which he was to keep for at least 13 years. While so engaged he attested the Wiltshire election indentures of 1447 and 1453. A significant factor in his several elections to Parliament is likely to have been his business in the law courts at Westminster. There he regularly acted as an attorney in the common pleas and King’s bench for landowners from his home county, such as Henry Chancy*.
Uffenham often had personal dealings with his fellow MPs. In April 1449 William Kayser* of Wilton (who was to be his companion in the Parliament which met in November) mortgaged his lands to him for 40 marks,
On occasion, Uffenham’s probity might be called into question. As a feoffee for John Bartour of tenements in Sutton Mandeville and Tisbury, he conveyed them to Bartour and his wife Edith in 1454, only for Bartour to claim in a petition sent to Chancery several years later, that after Edith’s death he had refused to release his title.
Uffenham was actively employed throughout the 1460s and 1470s as bailiff of the liberties in Wiltshire belonging to Bishop Waynflete of Winchester, and certain major religious houses, and he continued to be favoured as a candidate at parliamentary elections. At Wilton on 30 Aug. 1469 he was elected to the Parliament summoned to assemble in York, although in the event it did not meet,
John Uffenham the younger had followed his father into the legal profession, becoming a member of the Middle Temple.
