Sir John Perceval, 1st Baronet (7 September 1629 – 1 November 1665) was an Irish nobleman and landowner. He was knighted by Henry Cromwell for his services to the Commonwealth government of Ireland during the Interregnum. Shortly before the Restoration, he held the offices of Chief Prothonotary of the Common Pleas and Clerk of the Crown. After the Restoration, he was granted a baronetcy and given a full pardon for his activities during the Interregnum. He was appointed Privy Councillor to King Charles II, a Knight of the Shire for County Cork, and was a member of the Council of Trade.
John Perceval was born on 7 September 1629 in Dublin. He was the eldest son and heir of Sir Philip Perceval (1605–1647) (the son of Richard Perceval) and of Catherine, the daughter of Arthur Usher of Dublin, and grandson to George Perceval. He was tutored in the home counties of England alongside Lord Inchequin's eldest son who had been placed under the guardianship of Sir Philip Perceval while his father was engaged in the Civil War in Ireland. John Perceval went to Cambridge University in February 1646 when he was sixteen.
While at Cambridge he met and befriended Henry Cromwell. His father died the following year, and John Perceval decided that, with wars raging in both England and Ireland, he would remain at university and so remain out of public life to avoid choosing sides in the wars. In 1649, after the execution of Charles I, the rebellion in Ireland was crushed by the New Model Army under the command of Oliver Cromwell. Given Perceval's large holdings in Ireland, he thought it politic to return to protect his interests. This was difficult because his father had opposed the English Independents who were now in the ascendancy.
As well as protecting his lands, Perceval proposed to marry the daughter of the Speaker of the Rump Parliament William Lenthall who would then protect his estates for the benefit of his daughter. However, with the diminution of Lenthall's influence within the Commonwealth, the marriage fell through.
Perceval's father Sir Philip Perceval, was in the Irish government and originally supported Cromwell. However, he later opposed the New Model Army. On his death, Cromwell calculated that his son could be of use and he protected John Perceval's interests in the short term, hoping to use him as an ally in the longer term. The first example of this support occurred in England in 1650 when the Somerset sequestration committee proposed that Perceval's holdings in Somerset should be sequestrated. The matter was taken up in London and, through Cromwell's intervention, settled in favour of Perceval.
In Ireland, the Commonwealth sequestered all of Perceval's estates. Perceval prevented absolute confiscation and as his interests improved, this severity relaxed. However, he was obliged to pay large sums to the Commonwealth. For example, in the year 1 May 1650, to 1 May 1651 for his Munster estate, he contributed £1,965 and, in the following year, his contribution amounted to £200 more than the estate produced.
Once Sir John Perceval was of age, he laid claim to all of his father's estates in Ireland, amounting to seventy-eight and a half Knight's Fees, containing 101,000 acres, of some of the best land in Ireland. There were holdings in the counties of: Cork, Tipperary, Catherlough, Waterford, Kerry, Mayo, Kildare, and Dublin. There were some other estates over which he had control, some were already in his possession, some belonged to his mother, and he was also paid a small amount of rent from housing in Dublin City. Oliver Cromwell, who was in Ireland finishing his campaign against the Irish confederates and Royalists, supported Perceval in his claim.
When Cromwell left Ireland in the middle of May 1650 to take the war to Scotland, (and on to the Commonwealth's ultimate victory at the Battle of Worcester on 3 September 1651), Henry Ireton, his son-in-law, remained in Ireland as Lord Deputy in Cromwell's place. Militarily he met little further resistance and was left with a mopping-up operation. After his death, his successor, Edmund Ludlow, was faced with even less effective military opposition, and after Charles Fleetwood arrived in Ireland with supreme command, the English establishment was confident enough of their hold on Ireland that the English Parliament declared the rebellion totally subdued on 26 September 1651.
The next issue facing the English Parliament was what sort of settlement to impose on Ireland. This included a High Commission to try those who had been in arms against the Commonwealth, many of whom were transported and their lands sequestrated, and the banishing of known Roman Catholics to Connaught and the confiscation of their lands. Oliver Cromwell sent Sir John Perceval to assist General Charles Fleetwood with this task. Fleetwood was impressed with Perceval's service, and wrote to England saying as much. In recognition of this service, Perceval was granted the office of King's Bench, which had been sequestrated with his estate from the time of his father's death. On 6 July 1653, the office of Commissioners of Revenue was told to allow him to receive the entire income from his estates. To provide a suitable living for himself, pay off some of his father's debts, and form a dowry for his sister, he sold 15,000 acres of his best land in a depressed market.
In December 1653 the Council of Officers introduced a written constitution into the Commonwealth called the Instrument of Government and under its provisions declared Oliver Cromwell Lord Protector. Perceval travelled to London in May 1654 and while there renewed his friendship with Henry Cromwell and had an audience with Oliver. He was invited to sit in the First Protectorate Parliament but declined because he thought that his public and private commitments in Ireland should take priority.
When he saw what a debacle the First Protectorate Parliament had become, Perceval decided to distance himself from the regime, concluding that it could not last. He had been working with Roger, Lord Broghill and one of his tenants, Vincent Gookin, in the interests of the Commonwealth but, on his return from England in July 1655, he retired to his castle at Liscarroll and tried to keep out of public affairs as much as possible. It was during this sojourn that he married and started a family (see below). He worked to improve his estates by inviting Protestant farmers to take up tenancies while retaining Roman Catholic tenants who had proved loyal to his family during the rebellion. When his friend Henry Cromwell arrived in Ireland as the New Deputy Governor, Perceval had no choice but to take a more active role in government as to do otherwise would have aroused suspicion. In November 1656 Oliver Cromwell appointed him one of the "commissioners of the Security of his own Person and Continuation of the Nation in Peace and Safety". This meant that Royalist supporters saw Perceval as one of the stalwarts of the Protectorate. Cromwell invited Perceval to sit in Cromwell's Other House but he declined. Despite this he was knighted by Henry Cromwell on 22 July 1658 for his services to the Commonwealth.
It was largely due to the counsel of Perceval that Henry Cromwell stayed out of the anarchy that engulfed England after the death of his father; in particular his passive behaviour over his elder brother Richard's removal from the office of Lord Protector. This political move by Perceval stood him in good stead during the brief return of the Long Parliament and the Convention Parliament. In turn, he was appointed one of the four councillors to the President of Munster, and appointed by those commissioned by the President to manage the government of Ireland, Clerk of the Crown, Prothonotary of the Common-Pleas, and Keeper of the Public Accounts on 7 May 1660 preceding the return of the King on the 29th of the same month.
Soon after the restoration of the monarchy he was sworn in as a member of the Privy-Council, and on 9 September 1661 created Baronet Perceval of Kanturk. To secure his position, and so that his political enemies could not in the future use his conduct under the Commonwealth to attack him, Perceval obtained a Patent of Special Pardon for all treasons, rebellions, etc. and for all engagements, of which he might have been guilty, either under the Parliament of the Commonwealth, or the Protectorate, from the beginning of his life, to 29 December 1660. The Patent was dated Westminster, 22 April 1662 and was passed under the Great Seals of England and Ireland.
