Cerf hailed from a family of small freeholders established at Newhay near Hemingbrough since at least the reign of Edward III.
Cerf, however, also had interests in Northumberland. In November 1420 he was named as escheator there, and three months later he was described as of that county when he entered into a recognizance with the King that royal rights would be honoured in respect of the marriage of Alice Cramlington of Cramlington, a few miles to the north of Newcastle-upon-Tyne. What is not clear is whether he held property in the county in his own right; it is known only that, while serving as escheator, he was granted the keeping of land there in royal wardship. On 17 July 1422 Henry V committed to him the wardship and marriage of John, the young son and heir of a wealthy Newcastle merchant and landholder, Thomas Hebburn†. Since the heir was a mere infant this grant was a potentially valuable one, and our MP had acted quickly to obtain it for it was made only 16 days after Thomas’s death.
Northumberland was, however, too remote a base for one who hoped to make a career in the Exchequer. Indeed, it may be that Cerf only fitfully discharged his responsibilities for, throughout his tenure of the office, he periodically acted as Exchequer attorney, routinely appearing for the sheriffs of the northern counties when they came to make their proffers at Easter and Michaelmas.
In the late 1420s Cerf spent enough time at his home at Hemingbrough to fall foul of a knightly neighbour. On 24 June 1427, according to an indictment laid before the East Riding j.p.s at York castle two months later, he, at the head of armed gang of some 100 men, destroyed various enclosing ditches set up by Sir Robert Babthorpe at ‘Brakenholmebyrnd’, which, it was subsequently claimed, illegally impeded the rights of common pasture enjoyed by the prior of Durham’s tenants in the lordship of Hemingbrough. Babthorpe, who as steward of the King’s household was a powerful adversary, added to the pressure by suing out, in the following October, a commission of oyer and terminer in respect of the same offence.
In any event, Cerf’s career at the Exchequer was unaffected. He benefited from minor Exchequer leases in 1427 and 1428, and began to act routinely as a mainpernor for grantees of increasingly higher standing. Between 1430 and 1432 he offered surety for Robert Warcop*, Sir Robert Roos*, Sir Thomas Cumberworth* and Richard Neville, earl of Salisbury.
Yet, although Cerf maintained and extended his local interests – he even found time to act as under sheriff in Yorkshire under Sir Henry Brounflete – the main focus was the Exchequer. His career there reached its apogee on 8 Nov. 1435, when the treasurer, Ralph, Lord Cromwell, named him to the important office of remembrancer. This brought, above a generous annual salary of 40 marks, an additional fee of the same sum and other unquantifiable benefits, notably a fee from each official who came to make account at the Exchequer.
The office of remembrancer left Cerf less time for local affairs. Significantly, when his income was assessed at £20 p.a. for the subsidy return of 1436, the assessment took place in London rather than Lincolnshire or Yorkshire.
Ill-health may explain Cerf’s replacement as treasurer’s remembrancer in February 1444 by the rising official, Thomas Thorpe*. He certainly did not long survive his loss of office, making his will on the following 17 July. Thirty years of service in the Exchequer had eroded his local connexions, emotionally if not physically. Describing himself as a citizen of London, he wanted to be buried in the cemetery of the cathedral of St. Paul’s and he left ten marks for a chaplain to celebrate for his soul in the church of the Holy Sepulchre outside Newgate. His wife was to have the manor of Saxby All Saints for her life on condition that she remained single; on her death or marriage it was to pass to their grandson, Marmaduke Holme, in fee tail with a final remainder to Cerf’s right heirs. The condition that his widow should remain single was an ungenerous restriction, but it was balanced by the will’s final clause: she was to have all his un-bequeathed lands in Yorkshire not simply for life but in fee simple. He also remembered generously his former ward, Thomas Lisle, bequeathing the large sum of £100 to the marriage of Thomas’s daughter, Juliana. More strikingly, she was also to have to her and her issue the manor of Sawcliffe and lands in Whitton; the most likely explanation is that she was his grand-daughter and thus one of his coheirs in company with Marmaduke Holme. Cerf was dead by the following September when his will was proved.
Cerf’s widow later married, as his second wife, Master John Somerset*, the King’s physician and chancellor of the Exchequer. On 4 Aug. 1446 Brian Boys, presumably as a feoffee of our MP, released to the new couple and others all his right in Cerf’s lands. Among the rest were two other couples, John Holme and Denise, and Richard Portington and Juliana: since one of Cerf’s daughters is known to have married Holme, the probability is that Portington, who was probably a younger son of John Portington, j.c.b., of Eastrington (not far from Hemingbrough), was also our MP’s son-in-law. This latter couple were probably remembered in the will’s lost section.
