Son of a Northamptonshire clergyman of limited means, Tomkins worked his way through college, where he met Sir John Digby*, who took him into service and later appointed him tutor to his eldest son George Digby†. Tomkins relinquished his post at Magdalen College school in 1610, and probably accompanied Digby to Spain in the following year. Certainly, by his own account he travelled extensively, becoming an accomplished linguist.
It was doubtless Digby, high in favour at Court, who procured Tomkins a pension of £102 per annum in 1613, and arranged for his return for Carlisle on the queen’s interest during a visit to London in the following spring. Tomkins spoke only once during the brief session, on 25 May, when he insisted that Bishop Neile’s attack on the Commons represented a private opinion and not that of the episcopate generally.
At the general election of December 1620 Tomkins was replaced at Carlisle by Sir Henry Vane. Phelips, having been nominated at Christchurch by Lord Arundell of Wardour, chose to sit for Bath, passing his interest at Christchurch to Tomkins, who held the seat for the remainder of the decade.
In 1624 Tomkins and the courtier (Sir) Richard Wynn were returned at Ilchester, which had been enfranchised at Phelips’s behest in 1621. Tomkins turned this seat over to his brother-in-law Edmund Waller and sat for Christchurch, where Arundell promised that he would require no wages. He was not distinguished from James Tomkins* in the records of this Parliament and its two successors, but neither man made any great impact on proceedings.
As a duchy official, Tomkins was summoned before the Privy Council in November 1626 to certify his willingness to pay the Forced Loan. This placed him in a dilemma, as he explained to Phelips:
it was so much against my heart to subscribe in this manner (though the king my master shall command my life and all I have, with more ready obedience than I can well express, being I do not only honour him as my sovereign but love him as my master) that I resolved to avoid it with any fitness I could.
He offered to pay but insisted he was too busy to subscribe in person; this excuse was accepted, although he acknowledged that it might not have been a few weeks later, and admitted ‘if I had been put to it I would have subscribed twice rather than have run the hazard of undoing myself’. He advised Phelips not to temporize, but to either refuse or pay the Loan as the mood of his county suggested: the former would be popular locally, the latter would make a favourable impression on the king.
Tomkins was returned for Christchurch as an Arundell nominee once again in 1628, with the usual undertaking to serve gratis, by which time he had been appointed clerk to Queen Henrietta Maria’s Council, perhaps at the behest of Henry (Rich*), 1st earl of Holland, whose advice he had sought over the Loan 18 months earlier. This connection would explain his nomination to a committee considering petitions against Holland’s monopoly as royal exchanger (13 June). Ten days later, in his only recorded speech during the session, he explained that the grant had been approved by the Privy Council, being contrary neither to law nor to existing interests; nor was it responsible for the dearth of specie, which was caused by war.
In 1640 Tomkins helped to manage the queen’s parliamentary patronage, but did not apparently stand himself.
I have sometimes had conferences and disputes with some Jesuits (in foreign parts chiefly). I thank God my principles of religion were so grounded they could never shake me. I have been called by some of them an heretic in grain. But ... in regard of some relations, and in regard I received very civil usage from those of that religion in foreign parts ... I returned the like civility to them here as I had occasion.
He attributed his involvement in the plot to ‘affection to a brother-in-law, and affection and gratitude to the king, whose bread I have eaten now above 22 years’.
