By 1828, Kitchen & Peacock was active as a factor and button maker at Fargate.  The partners were Richard Kitchen (who had been listed alone in 1825) and John Thornton Peacock (1800-1864).  The latter had been born in Sheffield, the son of John (a cutler) and Hannah, and baptised on New Year’s Day in 1801.   The partners ended their arrangement in 1830.  Richard Kitchen later became a busk manufacturer and died on 23 April 1859, aged 72.  In 1833, John T. Peacock was listed as a merchant and bread, butcher, shoe, and pocket knife manufacturer at Pond Street.  In 1837, he was at Boardman’s Bridge (near Suffolk Road).   However, he was bankrupt in 1840, when he was described as cutler and dealer in knives.  He sold his stock – made for the ‘country trade’ – which included various blades, travelling cards, a hearth of tools for forging table blades, and a phaeton (Sheffield Independent, 28 March 1840).  In the Census (1861), Peacock was a lodger, living at Willey Street in the Wicker, and working as a steel merchant’s clerk.  He died in 1864, though no further details have been found.
