In 1776, William Urton was granted the trade mark ‘URTON’.  In 1787, William and George Urton (possibly brothers) were listed as pen and pocket knife cutlers at Colston Croft (trade mark ‘URTON TAGLIO’).  In the following year, William Urton registered a silver mark at Hall Street.  William and George later traded at Norfolk Street, but in 1791 were also in possession of a dwelling house with workshops at the bottom of New Hall Street, which was off Westbar (Sheffield Register, 15 April 1791).  In the Sheffield directory (1797), William and George Urton were listed together as surgical instrument makers at Norfolk Street (trade mark ‘URTON MADRID TAGLIO’).  They were bankrupt in the following year.  In 1811, William Urton was listed as a cutler at Queen Street.  The burial register of St Peter & St Paul churchyard recorded the deaths of George Urton on 15 July 1803; and William Urton on 15 November 1807.  Both were cutlers and presumably the individuals described above.
