Walter Thomas Doughty was born in Bristol, Gloucestershire, England in early 1890.
He was the son of Edward Frederick Doughty (b. 1859 in Lambeth), a confectioner, and Eliza Mary Ann Russell (b. 1862 in Rotherhithe), both Londoners who had married in St Pauls, Bermondsey on 14 November 1880. His mother and father initially lived with his widowed maternal grandmother Eliza Russell in London before resettling in Bristol around 1883.
Walter had six known siblings: Frederick Alonso (1882-1954), Alice Sarah (b. 1884), William Henry (b. 1886), Albert Victor (b. 1888), Grace Adeline (1892-1973) and Cecil Rhodes (1897-1959).
Walter first appears on the 1891 census living at 39 Martin Street, St Pauls, Bristol. The family relocated a number of years later to his parents' native London and show up on the 1901 census living at 7 Hockley Street in Hackey.
When the 1911 census was taken Walter was absent, apparently already at sea. His father was living at Bessbrook Home, a lodging house located at 39 Queen Square, Bloomsbury, London. He described himself as a widowed confectioner's sugar boiler. His youngest two children, Cecil and Grace, were recorded at 1 Suffiled Road, Walworth, Newington, London under the care of their paternal aunt and uncle, Thomas and Alice Miller.
When he signed-on to the Titanic, on 4 April 1912, he gave his local address as 65 Bridge Road, (Southampton) but he was living with his father at 39 Queen Square, London. His last ship had been the Oruba. As a second class steward he received monthly wages of £3, 15s.
Doughty, who was unmarried, died in the sinking. His body, if recovered, was never identified.
What became of Walter's father is unknown but he is believed to have remained in London.
His brother Albert later served in the Canadian Infantry and was killed on 27 September 1918.
