Barker & Davy was listed in 1797 as a table knife manufacturer  at Coalpit Lane (trade mark ‘BARKER / DAVY’).  The partners were William Barker (c.1769-1834) and David Davy.   Apparently, they were Quakers.  Davy was probably David Davy (1768-1846), from Keighley, who later launched his own cutlery business.  William Barker’s family origins are unknown, too, but he may have been baptised on 2 April 1769 by William and Sarah Barker from Newsholme, near Keighley (albeit the ceremony was at the parish church, not a Quaker meeting house).   Barker and Davy were briefly joined by Joseph Robinson, but he left in 1803.  Barker, Davy & Co was listed in 1811 as a merchant and manufacturer, Union Street.  Barker and Davy parted in 1816.  The former continued as a merchant and table knife manufacturer at Carver Street.  William Barker, merchant, ‘deservedly respected’, died at his residence at Western Bank on 18 July 1834, aged 65.  He received a Quaker burial in Sheffield.
