Mr William Moss was born in Cotham, Nottinghamshire, England in the closing months of 1876.
He was the son of William Moss (b. 1843), a domestic groom and gardener, and Mary Cutton (b. 1844), both Nottinghamshire natives who had married in 1870. His siblings were: Mary (b. 1871), Robert George (b. 1875) and Frank (b. 1878).
William first appears on the 1881 census living with his family at an unspecified address in Cotham. Sadly, his mother passed away later that year aged 37 and his father was remarried to the following year to Betsy Caunt (b. 1853 in Elston, Nottinghamshire). William gained three half-brothers: Herbert (b. 1885), John (b. 1888) and Harry (b. 1890) and the family moved to Grantchester, Nottinghamshire. On the 1891 census only William's sister Mary is shown living at their family address, Paradise, in that parish; William shows up as a visitor to an address in Balderton, Nottinghamshire, namely Horn Lane, the home of a Mr Lewis Hatfield and his family but he had no stated profession. His father died sometime around 1893.
When William went to sea is not certain but he had worked for the White Star Line for over a decade and had served aboard both the Cymric and Majestic between the years of 1901 and 1907.
He was married around 1905 to a lady named Susan (b. 1881 in Perthshire, Scotland) and they had a daughter, Elizabeth Mary, towards the close of that year. At the time of their daughter's baptism at St Michael's Church, Toxteth, on 7 January 1906, they were resident at 19 Lisburn Road in that locale and William was described as a seaman. The family's last known address in Liverpool was 38 South Front before they relocated to Southampton, likely to coincide with the movement of White Star's main port.
William would be absent from the 1911 census and likely at sea but his wife and child were listed as living at 37 Charlton Road, Freemantle, Southampton.
William was on board the Titanic for her delivery trip from Belfast to Southampton and when he signed-on again, in Southampton, on 4 April 1912, he gave his address as 37 Charlton Road, (Southampton). As first saloon steward he received monthly wages of £6. His last ship had been the Olympic.
William Moss died in the sinking. His body, if recovered, was never identified.
What became of William's widow and child is not clear.
