This enterprise was a table knife maker and was first listed in a Sheffield directory in 1797.  The partners were Robert Brady (1764-1822) and Samuel Marshall.   The latter is unidentified.  Robert Brady was the son of Thomas Brady and his wife, Rachel née Saunderson.  Thomas was a carpenter, who lived at Thorne, Yorkshire.  The family members were Quakers.  Possibly the family had links to Jarvis Brady, who was also from Thorne.  Robert was apprenticed to Joseph Clarbour, a cutler, in 1778 and was granted his Freedom in 1791.  Clarbour was also a member of the Society of Friends.  In 1795, at a Quaker Meeting House at Doncaster, Robert married Elizabeth, the daughter of Thomas Holland, a cutler at Grimesthorpe.  In 1805, Brady and Marshall ended their partnership.  In 1811, Samuel Marshall (possibly the same individual) was listed as a table knife cutler at West Street; but not thereafter.  Robert Brady, too, disappeared from directories.  He died on 16 August 1822.  His ‘relict’, Elizabeth, died on 2 March 1823, aged 51.
