The name ‘John Simpson’ was listed in directories between 1822 and the 1840s – first in Bailey Lane, then Pea Croft, then Scotland Street, and finally Edward Street.  He manufactured Spanish knives (daggers), lock knives, pocket knives and spoon knives.  However, John Simpson, pocket-knife manufacturer, Scotland Street, died on 20 November 1831 (aged 34) after ‘a lingering illness’.   He was buried in St Peter’s churchyard.   His wife, Mary, and her son Joseph Ridge Simpson (1820-1880) were both enumerated as cutlers in Scotland Street in the Census (1841).  In 1849, they were listed in a directory in Allen Street as shopkeeper and spring knife manufacturer, respectively.  Mary Simpson, the 62-year-old ‘relict’ of John Simpson, Solly Street, died on 8 April 1853.  She was buried at St Peter and St Paul.  By then, Joseph was listed as a patent lock knife and spoon knife manufacturer in Solly Street, where he also operated the Red House pub.  He combined the jobs of cutler and victualler (later running the Dolphin Hotel, Division Street), but by 1854 was declared bankrupt.  By 1861, he was living on the Ecclesall Road and working as a brewer’s traveller.  Joseph died in Netherfield Terrace on 20 August 1880, aged 61.  He was buried in Fulwood.
