An old East Anglian family, the Kerdistons attained the peerage in 1332 but died out in the legitimate male line in the person of William, Lord Kerdiston, nearly 30 years later. According to modern theory, the peer’s heir was his grandson, Sir John Burghersh† (son of Maud, his only legitimate child) but he had preferred to leave most of his lands to his bastard sons, Roger and Sir William Kerdiston†. Following Lord Kerdiston’s death, Burghersh and Sir William went to law over his estates. At a trial at Lincoln in 1370, the latter managed to persuade the court that he was in fact legitimate, so winning a verdict in his favour. Although Burghersh appealed against the verdict, the parties reached an out-of-court settlement in November 1371, by which Sir John was to have a manor and other lands in Lincolnshire and the manor and advowson of Stratford in Suffolk. Kerdiston was nevertheless able to gain Stratford in 1372, after his opponent failed to appear during further litigation in Chancery. Having obtained the Kerdiston lands in East Anglia, he was able to pass them on to his son, Sir Leonard, whose own successor was his son, Thomas, the subject of this biography. The existence of other claimants to these properties meant, however, that Thomas’s hold on his inheritance was never completely secure.
Evidence for Kerdiston’s early career and knighthood is lacking, but the fact that he associated with noted soldiers like Thomas, Lord Morley, Sir Thomas Erpingham KG, Sir John Keighley and Sir Brian Stapleton strongly suggests that he himself served in the King’s wars.
It is likely that Kerdiston was a retainer of one of his most important feoffees, the earl of Stafford. He again chose the peer for that role – along with two Stafford retainers, John Harper* and John Heton* – in early 1444, and he would appoint Stafford, by then duke of Buckingham, the supervisor of his will.
Either soon before or shortly after his father’s death, Kerdiston become embroiled in a dispute with Sir John Howard*. At one point their quarrel threatened to spill over into violence, prompting Sir Thomas Erpingham, one of the most important servants of the Crown in East Anglia, to write to the chancellor, Thomas Langley, bishop of Durham. Noting that the chancellor was probably aware of a ‘certayne travace’ between the two knights, Erpingham informed him that an assize in Suffolk would hear their dispute in a few days time. As both parties were planning to bring considerable numbers of supporters (who included lords as well as knights and esquires) to the assize, he feared a riot unless the bishop and other councillors took action. He suggested that the duke of Gloucester should intervene to ensure that the law took its course. The Council responded to the information from Erpingham by despatching privy seal letters to Kerdiston and Howard ordering them to behave peaceably at the assize.
The Kerdiston-Howard dispute was almost certainly about the Kerdiston estates. Howard’s wife, Alice, was a descendant of Margaret, an illegitimate daughter of William, Lord Kerdiston, and she may have laid claim to some of the Kerdiston lands, in spite of her ancestor’s illegitimacy. Although any such claim was probably frivolous, it is possible that Lord Kerdiston had provided for his bastard offspring with land.
The Howards and their associates were perhaps not the only members of the gentry with whom Kerdiston quarrelled in the 1420s, for he entered a recognizance for £100 to Lewis John* in 1426, possibly in connexion with another dispute.
More constructively, the disputatious Kerdiston also sometimes helped to resolve disagreements among his fellow gentry. When, for example, an attempt was made to end a quarrel between Walter Tailboys* and Sir John Keighley in 1427, he was one of those who received a recognizance from Tailboys and his feoffees on Keighley’s behalf, and he was a party to the settlement made when this dispute was eventually resolved.
As a knight with considerable estates, Kerdiston was well qualified to sit in Parliament, to which he was first returned alongside one of his feoffees, Sir John Carbonel*,
During the early 1440s, Kerdiston’s most immediate concern were his estates. His father had apparently enjoyed undisputed possession of the lands in East Anglia that the illegitimate Sir William Kerdiston had won for himself, but he faced a serious challenge to his own title. In 1425 he had come to an arrangement with Maud, the surviving daughter and coheir of Sir John Burghersh, and her husband, Thomas Chaucer*, by which he had conveyed his estates to them and they had re-conveyed them back to him, to hold from them as their feudal tenant.
It was perhaps some consolation to Kerdiston that both his wives had property interests, although there were disputes over those of his second wife. During his first marriage, he must have enjoyed possession of the Burnell manor of Great Holland in Essex, a lordship which Elizabeth Kerdiston held in jointure by reason of her first marriage.
Much more significant was the manor of Flore in Northamptonshire, one of the principal Trussell holdings. A lawsuit heard in King’s bench in 1443 indicates that the Kerdistons had obtained possession of it by this date. The suit, which took the form of an appeal made against Kerdiston by the widow of a murdered man, came to pleadings in Michaelmas term 1444. The widow alleged that early in the previous year he had provided shelter at Flore for the killers of her husband, William Birche, after they had shot him in the head and stomach with their bows and arrows. Kerdiston appeared in person in King’s bench to declare himself not guilty of this charge and to opt for a trial by jury, but there is no record of any such trial in the plea rolls, suggesting that the suit ended in a settlement out of court.
In the meantime, the Kerdistons appear to have surrendered their claim to Gayton, another Trussell manor in Northamptonshire, since that autumn they formally conveyed it to Zouche and two other feoffees of Margaret Trussell, Sir Thomas Green* and James Swetenham.
Kerdiston died on 20 July 1446.
Kerdiston’s heir was Elizabeth, his daughter by his first wife, since his only son, William, had predeceased him.
In January 1451 the escheator in Norfolk and Suffolk presided over inquisitions for the lands Kerdiston had held in those counties. The juries found that he had not died seised of any of the properties listed and that the MP, the grandson of a bastard, had unjustly intruded on to the Kerdiston estates. They also declared that the de la Poles had taken possession of Kerdiston’s lands in Suffolk during his lifetime (in accordance with the arrangement of 1442) and that they had entered those in Norfolk after his death. Finally, they stated that the heirs to the estates were Alice de la Pole, by now the dowager duchess of Suffolk, and John Howard*, even though the latter (the grandson of the Sir John Howard with whom Kerdiston had squabbled in the 1420s), was also descended from a bastard child of William, Lord Kerdiston.
