John Thelwall, a younger son of the Plas y Ward family, acquired a lease of Bathafarn Park near Ruthin early in the sixteenth century. Sir Eubule, his grandson, was the fifth of ten brothers, another of whom, Simon, sat for Denbigh Boroughs in 1593.
Thelwall’s inexorable rise up the legal profession was doubtless sponsored by a powerful patron, although none has been identified. He never gave a reading at Gray’s Inn, but, probably because of his position as a master in Chancery, he became both a bencher and treasurer of the society.
Always keen to further his own interests, Thelwall began pressing Ellesmere for an increase in Chancery fees immediately upon his appointment. Advised to investigate the legal precedents, he submitted his findings to the new lord keeper, Bacon. The case was referred to the judges, who hesitated to offer a ruling but were allegedly moved to approve a Privy Seal by Bacon, whose support for his subordinates’ case had been assured by a gratuity of £1,200. The impropriety of this transaction came to light during Bacon’s impeachment, and on 23 Apr. 1621 Thelwall was grilled before a distinctly hostile committee for grievances. Sir Edward Coke*, who was opposed to any diminution of the power of the Common Law judges, scorned the masters’ claims to be able to give ‘references’ which amounted to surrogate judgments upon suits, and other speakers attacked Thelwall personally for bending the rules on fees for his personal profit. Coke made a damning report to the House four days later, whereupon the masters’ Privy Seal was condemned.
In 1624 Thelwall, doubtless keen to avert any repetition of the 1621 fiasco, put himself forward for election in Denbighshire. He probably saw off a challenge from Sir John Trevor II*, who, though he had sat for the county in 1621, was forced to come in for Flintshire at a by-election. As might be expected, Thelwall’s staunchest supporters were his own family: the surviving returns for both 1624 and 1626 were signed by three of his brothers, a nephew and his more distant relative, Simon Thelwall* of Plas y Ward.
During the Parliament Thelwall was notably reluctant to involve himself in the investigation of lord keeper Williams, having to be ‘pressed’ to exonerate the latter from a corruption charge arising from his handling of a suit over the will of Sir Roger Aston*.
Williams may have attempted to revenge himself upon his infuriating subordinate at the general election of 1625, when he nominated his brother-in-law (Sir) Peter Mutton*, another of the masters in Chancery, for the Denbighshire seat, a scheme which came to nothing, as Mutton preferred to try his chances in Caernarvonshire. Nevertheless, Thelwall found himself facing two other candidates, Sir Thomas Myddelton II* of Chirk and Sir Thomas Wynne of Melai, who was supported by the Gwydir interest. Deeply apprehensive about his family’s prospects in a three-way contest, Thelwall’s nephew John Thelwall of Plas Einion went to Melai to ask the Wynnes ‘to slacken in the business’. His request fell upon deaf ears, and some days later Myddelton secured the support of the Wynnes on the understanding that he would pass his borough seat at Weymouth on to Sir Thomas Wynne. By the day of the election news of Sir Thomas’s death in the Low Countries had apparently reached Wales, which simplified matters greatly, as Thelwall accepted Myddelton’s nomination at Weymouth once it became clear he could not carry the day in Denbighshire.
Like many other Members, Thelwall steered clear of attacks on the duke of Buckingham in 1626: his only speech on the subject called for relief for those English merchants whose goods had been embargoed in France in response to the favourite’s detention of a French ship, a remark which may have reflected a new warmth in his relationship with the Myddeltons.
Thelwall opened his attack on 13 Feb. 1626, interrupting a debate about the improvement of ministers’ stipends to complain that Bayly had neglected to catechize his diocese, had made no attempt to provide many churches with regular sermons and had preferred an unordained man to a benefice. He enlarged upon these charges in a formal petition on 17 Apr., which accused the bishop of simony; of fathering a bastard child upon one of his servants; of granting parliamentary protections to ‘dissolute and vile persons’; of embezzling funds intended for the repair of his cathedral; of assault; and of nominating unqualified men ‘and others ... that understand not the language’ to benefices. As a result of Thelwall’s intemperate complaint an investigation was begun, but on 22 May Thelwall protested that Bayly had attempted to suborn the witnesses, an accusation which was added to the existing charges. The House agreed to allow the investigation to continue during the Whitsun adjournment, but the committee’s labours were lost at the dissolution on 15 June.
During the 1628 session Thelwall was one of the minor government officials who feebly attempted to smooth over the differences between Crown and Commons. Inclined to generosity in the supply debate of 4 Apr. 1628, he argued that ‘although no man serves for a poorer country than myself, yet I would give five subsidies’. Most Members flatly rejected the Lords’ proposed amendment to the Petition of Right on 20 May, but Thelwall attempted to paint the proposal in a favourable light: ‘neither the Lords nor we do anything in the Petition that may prejudice the king’s prerogative ... If we add anything to his prejudice, then we have cause to suspect this may prejudice the liberty of the subject which we have voted’.
While hardly a major politician, Thelwall made regular contributions to the Commons’ debates in several areas. His attack on Bishop Bayly may have been partially motivated by personal enmity, but it also drew upon his misgivings about the way in which the clergy valued their own preferment above spiritual matters, which he expressed most clearly at the third reading of the scandalous ministers’ bill on 16 May 1628:
I think it is time to complain of ministers when I, that have a dozen or fourteen of them within ten mile of me round about, the least of their benefices to the value of £50 per annum, may ride my horse a month and not hear a sermon. I believe they are not busied as they should be, and therefore it is time to think of a reformation.
Ibid. iii. 436.
A number of the bill committees to which he was nominated reflected this concern: the endowment of three lectureships (20 Apr. 1624); scandalous ministers (1 May 1624); simony (14 Feb. 1626, 23 Feb. 1629), which he claimed was commonplace under Bayly; advowsons (14 Feb. 1626); and encouragement of preaching (25 May 1626).
Thelwall regularly placed his legal expertise at the service of the House. In his maiden speech of 3 Mar. 1624 he secured a committee to draft a bill restricting the use of writs of habeas corpus by defaulting debtors, to which he was the first named; the scheme came to nothing, as no bill was subsequently tabled.
The only local legislation in which Thelwall showed any sustained interest was the bill to confirm copyhold tenures in Bromfield and Yale lordship in Denbighshire (1 June 1626; 9 Apr., 13 June 1628). He was the first MP named to the committee in 1628, and probably took charge of the bill during this session. At the third reading on 19 Apr. 1628, when Sir Dudley Digges criticized it for converting the estates to socage tenure, Thelwall insisted that the king ‘loseth nothing in his revenue future or present’. Despite his assurances, it was ordered that the bill be altered; the new draft eventually passed both Houses and received the royal assent.
Beyond the environs of the Palace of Westminster, Thelwall spent much of the 1620s atoning for the sins of his professional life with a vigorous programme of charitable works. At Gray’s Inn, he supervised the building of the chapel and the paving of the courts, while building a large set of chambers for himself. At Oxford he secured the first proper set of statutes for Jesus College, of which he became president in 1621, and was said to have bestowed nearly £5,000 of his own money upon the chapel and the library.
By the time Thelwall drafted his will on 24 June 1630, he had apparently already settled his main Denbighshire estate upon John Thelwall the younger of Bathafarn, heir to his eldest brother. He left a house in Theydon Garnons, Essex to his lawyer brother Simon and divided his chambers and law books at Gray’s Inn between the latter’s son Daniel and two other nephews. The rest of his books went to his brothers Simon and Sir Bevis, who were also to share his lease of the tithes of Llanrhydd, Denbighshire, while he left a mourning ring to his ‘cousin’ John Griffith II*. Having modified the will a few weeks later to take account of the death of his brother Simon, he died on 8 Oct. 1630. He was buried in the chapel of Jesus College, which still acknowledges him as one of its greatest benefactors.
