Originally from Devon, Sturgeon was one of three brothers, all of whom retained a connexion with their native county while pursuing successful careers within their chosen professions elsewhere. Their father was named Nicholas, almost certainly the Nicholas Sturion (fl.1398) of Ashburton who, along with another relative, Richard, exported tin, cloth and other goods through the ports of Dartmouth and Exeter in the late fourteenth century.
Younger by several years than his siblings, John Sturgeon did not embark upon his career as a London mercer until 1415-16 when he was apprenticed to William Ernton. He completed his apprenticeship and duly obtained the freedom of the city of London in 1425. His subsequent advance through the ranks of the craft was rapid: two years later, having presumably established a business of his own, he took on the first of the 14 apprentices which he enrolled during his career. He also passed through the first of the three stages of admission to the livery of the Mercers’ Company, a process which he completed in 1429. In July 1434 he was chosen as one of the four wardens of the craft (a position to which he was elected on another three occasions over the course of the next 20 years), and in 1436 he was among the ‘good men’ of the Mercers who approved the translation of Geoffrey Boleyn* from the craft of hatters to their Company.
Like many of his fellow mercers Sturgeon was active in overseas trade, and by 1436 had become part owner of a ship called the Marie which was based in the port of London. In September that year he and his partners were licensed to send their ship to sea for ten weeks against the King’s enemies and to take possession of any merchandise they seized from enemy vessels. Another man granted a similar licence that year was the Devon shipman Thomas Gille II* with whom Sturgeon may have maintained ties, for it was probably around this time that he profited from one of Gille’s acts of piracy. A petition submitted to Chancery by a merchant of the Hanse, Lambert Smyth, alleged that Gille’s ship, the Anthony of Dartmouth, had intercepted two vessels belonging to Smyth off the coast of Normandy and seized 26 tuns of white wine from La Rochelle. Some of the wine, bearing Smyth’s mark, was later found in Sturgeon’s possession.
The extent of Sturgeon’s domestic business dealings is apparent from the numerous debts owed to him by individuals from various parts of the country. Many of the debtors failed to answer in court and were outlawed, and it is likely that Sturgeon was never able to recover the sums owed to him. In January 1438, for example, Sir Thomas Malefaunt of Windsor was pardoned his outlawry in respect of a debt of £12 1s. 8d. owed to Sturgeon, while in October 1440 a similar pardon was granted to a chapman from Carlisle, perhaps one of his distributors. Other debtors hailed from Kent, Wiltshire, Lincolnshire and, significantly, Devon.
Sturgeon’s connexion with the Frowyks was a particularly close one, for by 1447 Thomas had married Sturgeon’s niece, Joan, the daughter of his brother Richard. In 1447-8, the Mercers allowed Richard Sturgeon to become a freeman of their mystery by redemption, on payment of 20s. to the Company. This was probably perceived as advantageous by the Mercers, for whom Richard may have been a valuable contact within the royal Chancery, but it also reflected his position as, respectively, father-in-law and brother of two prominent members of the Company.
Sturgeon also established connexions with other prominent mercers in the capital, by whom he was clearly regarded as a reliable trustee. In April 1443 he and John Gedney* were among those who entered into bond in £1,000 with the chamberlain of London for the patrimony of Richard, son of Robert Large*;
As well as frequently finding sureties for his fellow mercers, Sturgeon also occasionally acted as a feoffee in London and elsewhere: in 1437 he was one of the feoffees of a brewery in Thames Street which was acquired by a brewer named John Broke; and by the early 1440s he had become a trustee of property in Rochester for William Chapman, a former master of the Tailors’ Company who died in 1446.
Sturgeon’s public career is well documented in the records of the City of London. In November 1437 he had been appointed as one of the receivers of the city’s portion of the tenth and fifteenth, and less than a year later he was chosen as one of the two common councilmen who were to serve as auditors, the traditional first step to higher office.
Sturgeon’s career as a common councilman in fact continued to prosper, suggesting that he had not lost the confidence of those in authority. In April 1443 he had been placed on an important committee with Stephen Forster*, Thomas Canynges*and others which was to deal with a dispute between the city’s linen-weavers and woollen-weavers. Another appointment came his way in October 1444 when, presumably in his capacity as a former auditor, he was chosen as a member of a committee which was to investigate William Wetenhale’s accounts as master of London Bridge; this inquiry dragged on for several years, and it was only in December 1447 that the committee made their report.
Yet once again this slight to his reputation did not prevent Sturgeon from continuing his work on the common council, and in October 1447 he was one of its two representatives entrusted with a key to the great chest in the city chamber. In September 1450 an opportunity for further advancement came his way following the appointment of the chamberlain, John Middleton*, as one of the sheriffs. Sturgeon was duly elected as chamberlain in his place, a natural appointment perhaps given his experience as an auditor and as a repeated member of financial committees. He held the post for four years, and in September 1454 in recognition of his good and diligent service he was granted an annual livery robe by the City as well as various rewards totalling £22 16s. 8d.
Sturgeon maintained a close relationship with his two brothers throughout his life. Nicholas died in the summer of 1454 and was buried in the chapel of St. Mary and St. Nicholas in St. Paul’s. In his will he left John ‘the hallyng with the ix wirthy and vi cuppes of sylver stondyng’, and bequeathed other silver vessels to John’s wife Beatrice. Not surprisingly both John and Richard were chosen as executors, along with their close associates Thomas Frowyk and Thomas Rykes, and over the next few years the executors were active in trying to recover sums of money from Nicholas’s debtors.
The date of John’s own death is uncertain, but it had evidently occurred by November 1464 when another mercer, Everard Brigge, was pardoned his outlawry in respect of a debt of £8 he owed to him. He left as his heir his synonymous eldest son who had already risen to prominence in Edward IV’s service and established himself in Hertfordshire. Another descendant was Henry Sturgeon (d.1526), a London ironmonger, whose own son and heir, John†, was returned to Parliament in the 1540s.
