It is often difficult to identify Timperley since he shared his name with both his father and eldest son. He is first heard of when John Mowbray, duke of Norfolk, appointed him and his father joint stewards and constables of the Mowbray pocket borough of Reigate in 1446, and it was probably about this time that he became the duke’s parker at Great Chesterford. By the second half of the 1440s a John Timperley was an esquire of the King’s household,
Like his father, Timperley played an extremely limited role as a royal commissioner in East Anglia and never served as a j.p. He was appointed to his first ad hoc commission a few months into the reign of Edward IV. Issued in July 1461, this ordered him and his fellow commissioners to take Buckenham castle and several manors in south-east Norfolk into the King’s possession. Sir Andrew Ogard* had purchased these properties from his father-in-law, Sir John Clifton, in 1447 but his young son and heir, Henry Ogard, was a ward of Henry VI’s queen and seen as a rebel by the new government. By the summer of 1461 the estate was in the hands of Clifton’s nephew, John Knyvet, and Knyvet’s son, William†, who had taken advantage of Henry’s absence to seize it for themselves. In September that year three of the commissioners (although not Timperley) rode to Buckenham, but they were refused entry to the castle, where John Knyvet’s wife, supported by a garrison of 50 men, had raised the drawbridge. In the following month Timperley was included in a new commission – which now included his patron, the duke of Norfolk, and John de la Pole, duke of Suffolk – but the Knyvets were able to persuade the Crown that they had a just claim to the Clifton lands before the commissioners could take action.
It is likely that Timperley owed his annuity to his association with the duke of Norfolk, since his letters patent referred to him as the duke’s servant. After his patron died leaving a 17-year-old heir in late 1461, Timperley remained loyal to the Mowbrays, becoming one of the new duke’s councillors.
It was as ‘late of Framlingham castle’ that Timperley acquired his royal pardons of 1462, 1468 and 1472,
Another widowed great lady for whom Timperley acted as a feoffee was Elizabeth de Vere, the dowager countess of the twelfth earl of Oxford, although in 1473 he and five co-feoffees discreditably agreed to convey her lands to the King’s brother, Richard, duke of Gloucester, who had coerced her into selling them to him.
No doubt through his association with the Mowbrays, Timperley came to form an important connexion with their relative and councillor, (Sir) John Howard*, subsequently Lord Howard. A member of Edward IV’s household and an important figure in his own right, Howard issued a livery of crimson cloth to either Timperley or his eldest son in May 1465.
Two years after the accession of Henry VII, the MP conveyed his manor and advowson of Hintlesham to a powerful group of trustees (possibly feoffees to the use of his last will) headed by John Morton, archbishop of Canterbury, and including the eminent lawyer (Sir) John Sulyard* as well as his son, William Timperley.
Shortly after Timperley’s death, his heir fell out with another of his sons, William Timperley. William staked a claim to certain of their late father’s lands in Suffolk, but the younger John Timperley declared that the lands in question were his by virtue of the settlement made for his marriage to Jane Howard.
