Jukes Coulson I (1751-1794) was a leading London ironmonger and iron merchant.  When he died at Paddington on 15 August 1794, he left his wife, Martha, £700 a year for life.  His nephew, Jukes Coulson II (1779-1854), next operated Jukes Coulson & Co, export ironmongers, at St Clement’s Lane, London.  He was joined by his eldest son, Jukes Coulson III (1800-1858).   By the 1840s, the former had retired to Clifton, where he died on 24 May 1854, leaving £500 to his son.   By the 1850s, Jukes Coulson & Co had offices in Birmingham and Change Alley, Sheffield.  In 1860, the firm was a general hardware merchant at Queen’s Steel Works in Holly Street (besides London and Birmingham).  Coulson exported trade knives (known as buffalo or chief’s knives) to North American fur companies (such as the Hudson’s Bay Co), trappers, and Native Americans (Russell, 1967).  Marks seen on Coulson knives include ‘FOX’; an arrow head and letter ‘I’; and ‘NON*XLL’ (the use of the latter is perhaps explained by Coulson hiring William M. Broadhurst, as agent).   Jukes Coulson III died on 31 May 1858 at Burleigh Villa, Bridge Road, St John’s Wood, Middlesex, leaving under £8,000.  His widow, Catherine Dunlop Coulson (c.1818-1893), became senior partner.  

During the 1860s, Thomas Newton Stokes (c.1818-1883) became manager.  In the 1861 Census, Stokes – who lived at The Priory, Totteridge – described himself as a wholesale ironmonger, employing 18 men, seven boys, and two women.  By 1870, he was a partner in Jukes Coulson & Co, which was listed in Sheffield at Carver Street.  Stokes died on 11 January 1883, leaving £82,884.  Jukes Coulson, Stokes & Co continued to be listed at Queen’s Works, Furnival Street (with A. C. Goodinson as manager), but switched to selling steel, files, and engineers’ tools.   It was bankrupt in 1908.   JCS High Torque Ltd, an engineering company, became its successor.
