In 1861, this firm registered a silver mark from Division Street.  The partners were John Pryor (c.1820-1900) and Edward Tyzack (1825-1910).   Pryor was a silver brazier, who may have been the silversmith recorded in the Census (1841) in Granville Street.  If so, his mother was probably Ann Pryor (though a link with the scissor-making Pryor Bros has not been confirmed).  Edward Tyzack was apparently the son of William Tyzack, a silversmith, and his wife, Ann.  In 1841, William lived in Wicker Lane.  

Pryor and Tyzack recruited Charles Sharman as partner, who is difficult to identify, but may have been the individual who became manager at George Wostenholm and was later an Alderman.  Sharman’s obituary stated that his wife was a ‘Pryor’ (Sheffield Independent, 8 October 1900).  In 1864, this partnership ended and the firm became Pryor & Tyzack.  This was, in turn, dissolved in 1867.  Edward continued alone as a plated ware manufacturer in Division Street.  In the Census (1871), when he was living in Brincliffe Edge, he stated that he employed forty workers (22 men, 6 boys, 10 women, two girls).  He did not employ them for long, as in 1874 the premises in Division Street were offered for sale.  

Edward Tyzack continued to work as a silversmith, while his former partner became a manager in an electro-plate enterprise.  John Pryor, silversmith, died at his residence in Upper Pearl Street on 19 May 1900, aged 80.  He was buried in the General Cemetery.  Edward Tyzack’s burial in Ecclesall churchyard was on 5 November 1910.  He was aged 86.
