Like many of the MPs of the borough of Stafford, Clerk was a servant of Humphrey, earl of Stafford and duke of Buckingham. He may have been active as early as 1419 when a Roger Clerk of Cotes, near Stafford, witnessed an exchange of lands between a burgess of Stafford, John Ashby, and the priory of St. Thomas the Martyr in the town.
Although there is nothing to indicate that Clerk attended an inn of court, it is clear that he had a legal training. In the 1440s, if not before, he acted as clerk of the peace in his native county. To this he added a minor place in the administration of the earl of Stafford. On 20 Oct. 1439 he was appointed clerk of the earl’s courts in Staffordshire, and, from the middle of the following decade he became one of the workhorses of the duke’s local administration. On 25 July 1445 he joined a prominent Stafford retainer, Humphrey Cotes, in drawing up a new rental for the duke’s property at Bridgnorth; and by the summer 1451 he was acting as steward of the duke’s manor of Drayton Basset (some miles to the south of Stafford), recently acquired in controversial circumstances from Sir Ralph Shirley†.
The duke’s death did not mark the end of Clerk’s career, for on 16 Apr. 1467 he headed the attestors to the Staffordshire parliamentary election as one of the county’s four coroners. It may be that he had already held that office for some years – it would explain his attestation of two earlier county elections – but he probably did not hold it for much longer. In any event no further references to him have been traced.
