The first of his family to settle in East Anglia, it is often difficult to distinguish Timperley from his son and namesake, whose own son was yet another John. The various (and conflicting) pedigrees relating to the Timperleys of Suffolk do not help matters, since one of them suggests that the MP had a younger brother of the same name.
Timperley had become active in East Anglian affairs by the later 1430s, since he attested the return of Suffolk’s knights of the shire to the Parliament of 1437 and was appointed escheator in Norfolk and Suffolk in November 1439. It is even possible that he saw military service abroad in the meantime, since John Timperley was a member of the force with which Sir William Bucton, captain of Lisieux, rode to the relief of the fortress of Le Crotoy in Picardy in the latter part of 1437.
In spite of serving as escheator, Timperley never became a j.p. and his role as an ad hoc commissioner was an extremely limited one. He did, however, help the duke of Norfolk to put down the disturbances which broke out at Norwich in January 1443. After quelling the trouble, Mowbray sent him to London with several prisoners, who were committed to the Tower. The King’s Council, which entrusted him with various messages to take back to his master, gave him £3 6s. 8d. as a reward, along with a further five marks for his expenses.
Given the duke of Norfolk’s limited influence in East Anglia politics in the 1440s, it is unlikely that Timperley owed his seat in the Parliament of 1445 solely to his master’s support. He certainly did not depend on Mowbray patronage alone during his career. In 1439 the Crown had provided him with a corrody at Thetford priory as a reward for his good service;
Timperley remained active in East Anglian affairs after acquiring his interests in Surrey. He was one of those who attested the return of Suffolk’s knights of the shire to the Parliament of February 1449, and in 1451 he appears to have assisted John Paston* in his dispute with Robert Hungerford, Lord Moleyns.
Yet, notwithstanding his actions at Stockton, Timperley managed to maintain a friendly relationship with prominent members of the de la Pole affinity like Sir Thomas Tuddenham* and Reynold Rous*. In March 1454 the Crown licensed him to have the manor and advowson of Hintlesham (which he had probably only just acquired) settled on himself and his feoffees, among them Tuddenham, Rous and John Wymondham, of whom the latter was by then another de la Pole man.
In spite of his association with members of the de la Pole affinity, it is likely that Timperley accompanied the duke of Norfolk to St. Albans in May 1455. Norfolk’s party arrived there on 23 May, a day after the duke of York’s defeat of the King’s army, no doubt because the duke was too circumspect to commit himself to either side.
For want of a will or inquistion post mortem, evidence for the MP’s lands is piecemeal. As already noted, he had held several manors at Sutton in the right of his wife, acquired property at Hintlesham and received lands in Surrey and elsewhere from the duke of Norfolk. He may also have held a manor at Merstham, given the licence to empark there granted to him in 1449 and the pardon he received, as of that Surrey parish, in 1452.
