This cutler and silversmith became active during the First World War at Holly Street. The partners were George Arthur Clark (1865-1940) and Gertrude Brown nee Marshall (1858-1938). Clark had been born at Leeds, the son of George (a Sheffield-born cabinet maker) and his wife, Emma.  Gertrude had married in 1882 Henry John Brown (1846-1912), who was a nickel silver caster. Unusually, in 1890 she (and not her husband) had registered a silver mark (GB) from Globe Works, Penistone Road.  She was listed in the local directory at that address as a silversmith and pepper and mustard top maker. She resided with her husband at 78 Malinda Street. For some reason, he was not listed in the local directory (was this to avoid a clash with other Browns with similar initials?).  Only later – for example in 1901 – was Henry John Brown listed as a silversmith. The couple lived at 8 Stumperlowe Avenue. Henry John died on 24 October 1912, aged 65, and was buried at Ecclesall. 

By 1925, Gertrude had apparently withdrawn from the partnership with Clark and was listed as a nickel silver ingot caster at Carver Street. Clark & Brown (under George A. Clark) was still at Holly Street. But within a year of so, Clark had become a partner in Clark, Hardwick & Co.  Clark & Brown disappeared from directories. Gertrude Brown died in 1938, aged 79. George A. Clark, who lived at Totley, died on 6 February 1940, leaving £4,083. His grave is at Abbey Lane Cemetery.
