Mr Christopher William Light was born in Southampton, Hampshire, England on 25 December 1891.

He was one of thirteen children born to James John Light (b. 1862), a coal porter, and Annie Emma Nicholas (b. 1870), Hampshire natives who had married in Southampton in 1887. 

His siblings were: Frederick James (1889-1959), George Thomas (1890-1971), James John (1893-1909), Thomas Alfred (b. 1894), Annie Kate(1) (1896-1985), Bertie (1897-1897), Edith Rosetta (1899-1899), Colin Henry (1900-1926), Alfred Edward (1901-1933), Florence Emily (b. 1903), William Henry (1906-1960) and Rosetta Ethel(2) (1908-1969).

Christopher first appears on the 1901 census living with his family at 25 Back of Walls, Holy Rood, Southampton. When the 1911 census was conducted the family were listed at that same address (now described as Lower Back of Walls) but Christopher was absent and presumably at sea.

When he signed on to Titanic on 6 April 1912 Christopher gave his address as 24 Lower Back of Walls, Southampton and his previous ship as Olympic. As a fireman he could expect monthly wages of £6.

Christopher Light died in the sinking and his body, if recovered, was never identified. 

His grieving family back in Southampton were dealt a further blow when Christopher's mother died before the close of the year. His father died in 1921 and several of his surviving siblings went on to die as young adults. His last known surviving sibling was his oldest sister Annie who died in Southampton in 1985.
