Barnes’ advertisements in Sheffield directories of 1839 and 1841 featured a quaint engraving of Barnes’ works behind a prim wall.  He made scissors, pen, pocket, and table knives and was also a general dealer in cutlery.  Matthew Barnes (1803-1848) was the son of George (a cutler) and Mary.  The enterprise was listed at Westbar Green (1828) and Cross Smithfield (1833), when Barnes was also running a beer house.  After 1837, his address was Allen Street.  In the Census (1841), Barnes was listed as a cutlery manufacturer, living at Allen Street with his wife, Maria née Turkwine (1806-1861), who was from Haxey, Lincolnshire.  They had married in Sheffield in 1828 and had a son, Alexander (1840-1862).   Matthew Barnes died at Allen Street in 1848 and was buried at St John’s, Park, on 21 May.  Maria continued to trade as a spring and scissor knife manufacturer at Kenyon Alley.  She was joined by Alexander.  In the Census (1861), Maria Barnes & Son was listed at Hollis Croft.  She died in 1861 and was buried at St John’s on 1 November; Alexander’s burial was on 9 March 1862.
