Charles Edward Sangster was born in Southampton, Hampshire, England in 1882 and his birth was registered in the June quarter of that year. He was the son of William Sangster (1851-1946) and Louisa Ward (1852-1937), both natives of Southampton who had married there in 1873.
Charles was one of twelve known children born to his parents, his siblings being: William James (b. 1874), Louisa Jane (b. 1876), Ellen Eliza (b. 1878), Alice Emily (b. 1880), George (b. 1884), Edward (b. 1886), Elizabeth Jane (b. 1888), Hilda Jessie (b. 1890), Lillian (b. 1892), Albert Henry (b. 1895) and Arthur (b. 1897)
Charles first appears on the 1891 census when he and his family are living at 18 York Street, Northam, Southampton and where his father is described as a boilermaker. Charles is absent from the family home by the time of the 1901 census but his family is listed as living at 1 Grove Street, St Mary, Southampton.
Charles was married in Southampton in mid-1908 to Charlotte Tyler (b. 1880 in Southampton, daughter of William Tyler) but he was widowed within a few months when his wife died in early 1909. He did not remarry. When he appeared on the 1911 he was again living with his parents and siblings at 46 Wilton Street, Southampton and was described as a widowed marine fireman.
When Charles signed on to the Titanic, on 6 April 1912, he gave his address as 83 Bevois Street (Southampton). His previous ship had been the Olympic and as a fireman he could expect to earn monthly wages of £6.
Charles Sangster was lost the Titanic disaster. His body, if recovered, was never identified. His mother and father continued to live in Southampton where his father died in 1946 and his mother in 1937.
