William ‘Billy’ Carlisle was baptised in Sheffield on 16 May 1785.  He was the son of Joseph Carlisle (1762-1837), a table blade forger, and his wife, Mary.  By 1828, he was listed as a manufacturer of table knives at Grindlegate.  By the late 1830s, he had moved to Orchard Lane and was also an ivory cutter (which suggests a link to the Carlisle brothers).  William was insolvent in 1846, but apparently recovered from the setback and continued to operate in Orchard Lane.  He told the Census in 1851 that he employed thirteen men.  In the following year, he vacated the Orchard Lane premises in favour of horn merchant Thomas Jarvis (who had partnered John Merrill).  William moved to Orchard Street and was listed in the directory of 1856, but not thereafter.  His death and burial are untraced so far, but he may have died by 1858.  His 76-year-old widow, Mary, was living in Orchard Street (Webster Place) in 1861 and told the Census that she was ‘formerly table knife manufacturer’.  She died on 9 September 1861, leaving effects under £100.  An advertisement appeared for the sale of William’s effects in The Sheffield Independent, 3 October 1861.
