Parkhurst’s forebears hailed from Norfolk, but settled during the sixteenth century in the adjacent Kentish parishes of Lenham and Boughton Malherbe. Parkhurst’s father has not been certainly identified, but a likely candidate is James Parkhurst, who by the mid-1580s was raising a family at Lenham, Parkhurst’s only recorded home in Kent.
Following Wotton’s recall in 1610 Parkhurst returned to Kent, but rejoined his master in 1612 on a mission to Turin aimed at promoting a marriage alliance between England and Savoy. When discussions collapsed at the end of the year due to Prince Henry’s death, Parkhurst found himself stranded at the duke of Savoy’s Court, Wotton having earlier been summoned home for negotiations in London. Morton, the official replacement as Turin agent, failed to take up his post until January 1615, apart from a brief visit during the previous summer, and Parkhurst by default took on this role.
Three months later Parkhurst was back at Turin, after briefly calling on Wotton in Holland. In June 1615 he provoked further diplomatic speculation by accompanying two Savoyard agents to Berne and Heidelberg, but this particular trip was sanctioned by Morton. Parkhurst finally left Turin for good soon afterwards, as in March 1616 he carried a government dispatch from London to Paris.
Parkhurst’s motives in seeking a place in the 1625 Parliament remain obscure. He was elected at St. Ives, where the borough’s principal patron was the 4th marquess of Winchester. Parkhurst’s route to a nomination there was probably via his Kentish friend and neighbour Sir Anthony Mayney, a former Member for St. Ives and an intimate associate of Winchester’s family, rather than through Buckingham, as has been suggested. Parkhurst was named as Mayney’s executor later that year, but he seems not to have sympathized with the prevalent Catholicism of Winchester’s circle, with which he was not otherwise visibly linked. He left no trace in the Parliament’s records.
Parkhurst was granted the wardenship of the Mint for life, initially in partnership with Villiers and then, from 1629, with Sir Anthony St. Leger. The post was not especially lucrative, offering annual fees of £100 shared between the joint wardens, with little opportunity for additional gain, though Parkhurst seems also to have used the official house provided at the Tower. Most of the routine management of the Mint was conducted by the master, technically a subordinate officer, and apart from a period in 1625-6 when Parkhurst served on a commission intended to reform the mastership, he was free to perform other tasks.
The cash-flow crisis precipitated by the Second Bishops’ War forced the government into a re-coinage programme in mid-1640, which Parkhurst supervised. He had already joined the king’s camp by August 1642 when Parliament seized the London Mint, and by the time he was officially removed from the wardenship in the following year, he had already helped to establish a rival mints first at Shrewsbury and then Oxford.
Parkhurst and St. Leger recovered their wardenship in 1660, and during the next few years presided over the re-minting of the old Commonwealth coinage and the adoption of mechanized production, programmes dictated by the government. Parkhurst’s main personal initiative, the manufacture of farthings of full intrinsic value to replace the customary tokens, was abandoned after 1665.
