A cadet member of a prominent East Anglian family, Clifton was a distant cousin of his contemporary Sir John Clifton of Buckenham Castle.
Clifton had an important responsibility thrust upon him at an early age because he was pricked as sheriff of Norfolk and Suffolk in November 1412, an appointment confirmed upon the accession of Henry V a few months later. When he came to render his account in 1413, he was pardoned the considerable sum of £160 since many of the old increments and profits of his bailiwick were no longer collectable or were of less value than in the past, and because the death of Henry IV had disrupted the exercise of his official duties.
The duke of Exeter returned to England after Henry V’s death, but it is possible that Clifton arrived home before him. Clifton continued his association with Beaufort following his return to England, since he acted as a mainpernor for the duke three years later, when the Crown granted Beaufort the keeping of certain estates which the late earl of March had held in East Anglia and south-east England.
Clifton did not begin his second term in the shrievalty until February 1423, although he accounted from the previous Michaelmas. As sheriff his name appears on the returns for Norfolk and Suffolk to the Parliament of that year, but he is unlikely to have attended both elections in person, since the two indentures bear the same date, 4 Oct.
Clifton was returned to his only known Parliament in the summer of 1433. During it the Commons granted the King a fifteenth and tenth, and shortly after it was dissolved he and John Roys*, his fellow knight of the shire, were commissioned to distribute allowances for that tax within Norfolk. One of the Parliament’s primary concerns was the problem of lawlessness, and the government imposed an oath for keeping the peace throughout the realm. It was again in their capacity as former MPs that the two men helped to administer this oath in their county in 1434.
In the same year Clifton was involved in a transaction by which Thomas Charles and his wife settled certain lands in Barmer and elsewhere in north-west Norfolk on him and his heirs.
In the same month the King’s Council appointed Clifton and the canon lawyer, Stephen Wilton, ambassadors to treat with the Holy Roman Emperor, the archbishop of Cologne and other imperial princes, and made each of them an advance of 100 marks. The purpose of the mission, during which both men received daily wages of 10s., is nowhere stated but it came in the wake of a rapprochement between France and Burgundy. The Emperor had recently declared war on the duchy’s ruler, Philip the Good, and it is clear that the English were seeking to form an alliance against their erstwhile Burgundian allies.
Clifton returned to the continent in the summer of 1439, following his appointment as constable of Bordeaux the previous March. He travelled to the duchy of Guyenne as a member of an expedition led by John Holand, earl of Huntingdon, whom the Crown had made lieutenant of Gascony. Holand’s household servants and retainers made up the bulk of his force, but it also contained contingents led by Clifton (who brought with him no fewer than 15 lances and 90 archers),
In the midst of this crisis Clifton died at Bordeaux, in the early hours of 23 Sept. 1442.
Clifton had made his will in the low chamber (‘camera bassa’) of Bordeaux castle, in the presence of John Blakeney*, a public notary from the diocese of Norwich who had accompanied Bekynton to France. Not surprisingly, given that he was in extremis when he made it, the will is a short one.
In December 1442 the Crown ordered the escheator to assign Alice Clifton her dower and to allow Clifton’s son to take possession of the lordship of Freebridge.
