Heyricke’s grandfather moved to Leicester in the late fifteenth or early sixteenth century. His father established himself as a prosperous ironmonger and served twice as mayor of the borough. The family business was inherited by Heyricke’s elder brother, Robert, who was elected to Parliament for Leicester in 1589, and was mayor three times before his death in 1618. Heyricke was the youngest of five sons and was apprenticed to the second brother, Nicholas, a successful London Goldsmith. By 1590 he had set himself up in business on his own account at the Rose in London’s Cheapside. He quickly diversified into money-lending to the nobility, and prospered sufficiently to buy the manor of Beaumanor, 12 miles north of Leicester, from the 2nd earl of Essex in 1595. The following year he married the sister of Humphrey May*, acquiring (Sir) Baptist Hicks* as a brother-in-law, and in 1601 he was elected to Parliament for Leicester with the support of both the corporation and the 4th earl of Huntingdon, for whom he acted as financial agent.
According to a petition he presented to Charles I in 1626, Heyricke made himself useful to King James before the latter’s accession to the English throne, presumably as a financier.
Heyricke was knighted in April 1605. According to Samuel Calvert, this honour was bestowed in recognition of the quality of his workmanship, but it seems likely that his substantial loans to the Crown also helped.
Heyricke retained close links with Leicester in the new reign. Indeed, in 1603 he provided plate, which the corporation presented to Anne of Denmark and Prince Henry on their journey south from Scotland.
Heyricke made no recorded speeches during the first Jacobean Parliament, but he was appointed to 14 committees, all of them in the second and third sessions, and most of them concerned with London or trade. On 22 Jan. 1606 he was named to the committee to consider the bill for the better execution of penal statutes, which was intended to abrogate patents dispensing with the penalties imposed by economic legislation. Two days later, when the committee was due to meet, the text of the bill and the committee membership list was delivered to Heyricke and George Blincowe. However, the following day Richard Martin reported that the committee had failed to meet. There is no evidence that Heyricke played any subsequent role in proceedings concerning the bill, which finally passed the Commons on 17 April.
In the third session Heyricke was named to five committees. The first, on 10 Dec. 1606, concerned the bill to reform abuses in the Court of Marshalsea.
In July 1607 Heyrick joined Sir Walter Cope*, Arthur Ingram*, Sir Thomas Lake I* and others in a syndicate for the sale of Crown lands, chiefly rectories and ex-chantry lands.
Over the next few years Heyricke continued to cultivate his interest at Leicester. In late 1613 he was active in helping the corporation with the purchase of property and the incorporation of Newarke hospital. On 12 Jan. his brother assured him that the corporation would ‘never forget your pains and kindness’.
With an eye to the future, Heyricke continued to help the corporation with the affairs of the hospital, receiving letter of thanks the following August for his ‘great pains, travel and good endeavours to many persons and places on behalf of our poor town’, together with a bottle of claret, a quart of sack and a pound of sugar.
In 1618 Heyricke was re-elected first warden of the Goldsmiths’, and in November, as part of a Privy Council investigation into the shortage of coin, helped examine the recent production of silver plate.
The appointment of his brother-in-law (Sir) Humphrey May* as chancellor of the duchy in 1618 strengthened Heyricke’s interest at Leicester, and he was re-elected for the borough in 1621. He was named to three committees and made 11 recorded speeches, but is not mentioned in the records of the Parliament after 26 March. His only legislative appointment of the Parliament was on 15 Feb., when he was appointed to the committee to consider the Sabbath bill.
On 26 Feb. Heyricke spoke in the debate about the ‘scarcity of money’. His primary concern was to place the blame for the country’s economic problems on merchants and patentees rather than his fellow Goldsmiths. One of the culprits he identified was the East India Company, for since its establishment in 1600 the output of the Mint had fallen dramatically. He also highlighted the export of coin to Poland, and raised the issue of the patents for making gold and silver thread and the manufacture of gold leaf, the former of which was a long-standing grievance of the Goldsmiths’ Company. Defending his colleagues, he cited the findings of himself and his fellow investigators in 1618, that the production of silver plate had declined rather than risen. Consequently, he argued, the ‘making of plate is not the cause of want of coin’. In Cheapside, where the ‘show of goldsmiths shops’ had been ‘the greatest in Christendom’, he complained that many premises were now empty and rents had declined, a further ‘sign that trade is decayed’.
On the following day Heyricke reiterated his argument that large amounts of coin were being exported.
Heyricke’s opposition to patents was not restricted to those that affected the goldsmith’s craft. On 12 Mar. he attacked Sir Francis Blundell’s* patent for licensing pedlars, stating that Blundell had sued over 1,000 petty chapmen in the Exchequer, including ‘divers of good worth, as the mayor of Leicester’.
On 29 Apr. three Leicester wool merchants wrote to Heyricke complaining that four years earlier the Staplers’ Company had been granted a monopoly of the domestic wool trade, as a result of which they had been forced to purchase their admission from the earl of Kellie for £111 each. Hearing that the monopoly was questioned in Parliament, they feared that their membership of the Company would be rescinded without compensation. They wanted either their money back or some guarantee that they would retain the privileges they had bought, and they asked Heyricke to advise them whether they should ‘exhibit a bill of grievances into Parliament-house’. If one had already been preferred by others, then they wanted him to add their names to it. Heyricke, however, seems to have done nothing to help, presumably because Kellie was his friend. On writing to the corporation after the end of the first sitting he claimed that ‘I cannot do them no good’ because Parliament had condemned the Staplers’ monopoly as illegal.
Heyricke’s career declined after 1621, probably because of his increasing money problems. He reckoned in the summer of 1621 that he was owed £8,104 by the Crown, of which £3,500 had been advanced in the previous May. In 1623 he sold his tellership to Edward Carne*. He relinquished his position as royal jeweller the following year, and thereafter lived mostly at Beaumanor.
