Samuel Marshall may have been baptised in Sheffield on 17 May 1786, the son of Martin (a cutler) and Ann.  By 1822, he was listed as a pen and pocket knife maker in Allen Street and continued to work there during the 1830s.  In the Census (1841), he was enumerated with his son Samuel in Allen Street.  Father and son were partners, but in 1843 Samuel Sen. became insolvent at an address in Eyre Street.  His son continued in business.  In 1851, Samuel Jun. was listed in the Census as a 36-year-old manufacturer of cutlery, who lived in Eyre Street.  In that year, Samuel was an exhibitor at the Great Exhibition, where he described himself as a ‘designer and manufacturer’.  He displayed ‘specimens of illustrated cutlery, consisting of razors, etc., carved in mother-of-pearl handles.  Gentleman’s pocket combs, etc.’ In 1852, the directory listed him as a table and spring knife, and razor manufacturer in Surrey Lane (with his home in Eyre Street).  His subsequent history has not been traced.  His father, though, emigrated to America.  The Sheffield Independent, 27 November 1852, reported his death in Matteawan, Duchess County, in New York.  He was aged 66.  Matteawan was the location of a group of Sheffield cutlers (see Thomas Bradley, James Roberts).
