Arthur had been born within the parish of St Mary's Church, Stockport. His parents, Arthur and Mary Effie, lived at 19 Clarendon Street, Sandy Lane, Stockport.
The 1901 Census shows Arthur, senior, to have been then aged 35 and working as a bricklayer. Mary, who had been born in Collingwood, Australia, was 36. Building seems to have been a family business as John Ridley, believed have been the grandfather of Arthur, junior, was a builder's foreman. He was then aged 61.
The Census also indicates that Arthur had an older sister, Effie, then aged 7, and a younger brother, John, aged 2. Also listed are two older men, John, aged 20 working as a joiner and Frank, 27. They are probably Arthur's uncles.
His service number confirms he was a pre-war member of the Territorials and would have been mobilised when war was declared in August 1914. The Battalion's early months are described here. An account of the attack in which he was killed can be found here. Arthur's body was never recovered and identified and he is commemorated on the nearby Memorial to the Missing.
