Of obscure origin, the Slegges probably lived in west Kent, perhaps at Brenchley near Tonbridge, in the early fifteenth century.
Whether through Clifton or the mooted association with the Brenchesles, Slegge had formed the connexion with the Fiennes family that would dominate the remainder of his career by the early 1440s. During this period James Fiennes*, who lived at Seal, a few miles to the west of Brenchley, was emerging as the dominant figure in Kentish politics, and in the summer of 1441 he was employing Slegge as an attorney at the Exchequer.
At the beginning of 1445 Slegge was elected as a baron for the Cinque Port of Hythe to the Parliament of that year, and in 1446 he claimed exemption from the parliamentary subsidy by virtue of his freedom of the Port.
In January 1447, following the summoning of the succeeding Parliament, Slegge attested the return of Fiennes and William Cromer* as the knights of the shire for Kent. The Parliament of 1447 saw the destruction of the duke of Gloucester and the elevation of Fiennes to the dignity of Lord Saye and Sele, and Slegge participated in the election alongside several of the latter’s supporters in the county.
If such grants were not undue reward for his service, Slegge’s involvement in private land transactions with Fiennes and others of his circle was potentially more controversial. The primary purpose of these, it seems, was to extend Fiennes’s influence in east Kent. In 1447 he witnessed a charter of quitclaim to Mereworth, a manor which Fiennes had purchased, and in the following year the widow of the long-dead Thomas Basings granted the manor of Kenardington to him and his patron. This may have been part of a deal by which Fiennes received the Basings lands in Kent in return for securing a pardon in the court of King’s bench for Alice, widow of Thomas Makworth*, the common law heir to the Basings inheritance who had been indicted for forcible entry.
On 6 Nov. 1448 Slegge became sheriff of Kent, an unusual appointment given his relatively humble origins. Marking the peak of his career, it was undoubtedly a measure of Fiennes’s influence in the administration of the county. In the following month Bishop Low of Rochester appointed him to arbitrate in a dispute between the cathedral priory of St. Andrews and the citizens.
As sheriff, Slegge also presided over the Kent elections held at Penenden on 6 Oct. 1449 to the following Parliament, although on this occasion only 14 men attested the return of the county’s knights of the shire, his friends John Warner and William Isle*.
Accordingly, the Crown was forced to issue a commission of oyer and terminer to investigate the charges levelled by Cade and his followers. Between 20 Aug. and 22 Oct., indictments were heard at Rochester, Maidstone, Canterbury and Dartford. The jurors made five specific charges against Slegge. The first indictment alleged that he and Fiennes had acted together in forcibly expelling Humphrey Eveas from his property at Elmley on the Isle of Sheppey in 1447. The second stated that he, Robert Est and several others had stolen animals and goods belonging to Roger Clitheroe in July 1449. A third alleged that, with Fiennes, he had unlawfully distrained the tenants of John Arundell for refusing to pay a rent surcharge unjustly imposed by them after Arundell’s death. A fourth made a more substantial allegation against him, namely that he, along with Fiennes and his wife, threatened Reynold Peckham* with imprisonment and death, forcing the latter to surrender property at Seal to Fiennes. Fiennes was supposed to have made over other lands to Peckham in exchange, an undertaking he had failed to honour. Soon afterwards, moreover, Fiennes and Slegge had unjustly distrained Peckham’s tenants at Kemsing and Sele. Finally, in September 1450 the hundred jury of Calehill and Chart accused Slegge of having, while under sheriff, extorted ten marks from a local man in 1441.
The modern editor of these indictments argued that the oyer and terminer commission was an attempt to respond to the complaints about the extortions and malpractices that Fiennes and his associates had committed in Kent over the past decade.
During the Parliament of 1450-1, Slegge was among those whom Commons, addressing the King, alleged ‘hath been mysbehavyng aboute youre roiall persone, and in other places, by whos undue meanes youre possessions have been gretely amenused, youre lawes not executed, and the peas of this youre reame not observed nother kept’. Headed by the duke of Somerset, the list was comprised mainly of men associated with the King’s household under the duke of Suffolk and Fiennes. The petition demanded that those named should remove themselves from the King’s presence and remain at least 12 miles from the Court for the rest of their lives. The King, while denying knowledge of any wrongdoing, assented to the petition with certain provisos, namely that the lords named in the petition and those that ‘have be accustumed contynuelly to waite uppon his persone’ should be exempted. The ban was reduced to a year, however, during which time all allegations against those named in the petition would be investigated.
The petition also opened the door to a raft of further charges against him. On 7 Feb. 1452, a Canterbury jury heard that in 1449 he and Robert Est had broken the closes of Edward Neville, Lord Abergavenney, at Shinglewell and Ifield and assaulted his servants.
On 22 June 1452 Slegge took out a general pardon, but this did not forestall further allegations against him.
Despite all the charges he faced, Slegge appears not to have suffered imprisonment, fine or forfeiture as a result of his part in the supposedly corrupt county administration of the late 1440s. As already indicated, most of the charges had local and personal roots. Doubtless, he had obtained land, grants and the advancement of his legal disputes through Fiennes’s patronage, but there is little to suggest that, helped by his patron, he had systematically and deliberately abused his position at either a local or national level. Similarly, although malpractice may have occurred at the parliamentary election for Kent in January 1449, there were no specific complaints about his conduct as sheriff. Nevertheless, Slegge played no part in the administration of the county after the events of 1450. Instead he seems to have concentrated on his connexions with Bishop Low and the group of lawyers at Rochester who were increasingly dominating the business of the city’s bridge. There are just a few references to his activities in the later 1450s. In February 1458, he demised his interest in the manor of Kenardington to a new group of feoffees acting for Sir John Cheyne II*.
Slegge made his will, dated 30 June 1460, at London, in the parish of St. Nicholas in Farringdon Ward. He sought burial in the chapel of St. Blaise in the parish church at Wouldham, to which he left bequests for its fabric and clergy. Slegge assigned his lease of the manor of Wouldham (which the prior and convent of Rochester had granted to him free of rent as a reward) to Simon Clive, and other properties to Thomas Clive with remainder to Rochester bridge. He also rewarded his servants with small sums of cash and ordered the settlement of debts with the executors of Lady Brenchesle. Whatever the extent of his past misdeeds, the will demonstrated a concern for his soul and a desire to right any wrongs he had committed during his lifetime. He instructed his executors to transfer possession of his manor-house at Wouldham to the abbot of St. Augustine’s, Canterbury – except for the chamber at the ‘nether end’ which was to provide a home for his widow – in return for an obit in perpetuity. Should the abbot not agree to this condition, his executors were to sell the property, ‘to make satisfaction of any wronges that any man resonably canne preve that I have in any wise trespasid too’. Slegge was also eager to right a wrong done against William Adam, with whom he had exchanged lands in Romney Marsh for others at Goudhurst. Adam had received the holdings in Romney Marsh, only for James Bowes, apparently with Slegge’s connivance, to dispossess him of them. Slegge ordered his executors to provide Adam’s heirs with land in the vicinity worth five marks p.a., and enough money to purchase a similar amount of land elsewhere. For the further good of his soul, Slegge bequeathed wheat to the poor of Wouldham and a year’s wages to each of his servants in return for their prayers. He also gave money towards the repair of Bishop Low’s house in Oxford, on condition that the bishop arranged masses for the souls of his father and mother, and made further provision for the spiritual welfare of his parents and others, among them three of his patrons, Archbishop Stafford, Lady Brenchesle and James Fiennes. For his executors, Slegge chose Thomas Cotyng, the chaplain William Gace and Simon Newton, awarding each of them £10 for their expenses and labours, and he named Edmund Chertsey as overseer of the will. He died before 21 Oct. 1460 when probate was granted.
The performance of Slegge’s will did not pass without incident. As instructed, the executors sold his property in Ruckinge, Snaith, Horsleton and Warehorne. The highest bidders were George Knolden and Alan Gayler, who promised to pay £83 6s. 8d., only for William Gace to sue them in Chancery for paying £80 rather than the full sum due.
