By 1849, James Innocent was a spring knife manufacturer and ironmonger in Trafalgar Street.  By 1852, he had moved to Charles Street, where he specialised in spring knives.   In 1854, the business was restyled ‘& Son’ and described as a ‘general cutlers’.  The son was apparently Joseph Innocent, who by the early 1860s lived in Sheaf Gardens Terrace.  However, James Innocent, ‘cutler’, Charles Street, died on 23 December 1861, aged 56.  He was buried in the General Cemetery (where his wife, Ann, had been interred in 1859, aged 52).  Joseph died, aged 30, on 23 July 1862.  The company ceased trading and was apparently acquired by John William Waterhouse.
