Mr Hubert Prouse Perriton was born over the summer months of 1880 in Southampton, Hampshire, England.

He was one of five children and the eldest son born to John Prouse Perriton (b. circa 1835), a ship's quartermaster, and Edith Cass (b. 1842). His father was originally from Ringmore, Devon and his mother from the Isle of Wight and they had married in Southampton on 24 September 1872.

His siblings were: Ida (b. 1873, later Mrs Julius Petersen), Laura Christian (1876-1958), Edwin John (1878-1878) and Archibald (b. 1882).

Hubert first appears on the 1881 census and at that time he and his family were living at 24 Nelson Street, St Mary, Southampton. The 1901 census shows that Hubert is absent from the family home, perhaps already at sea, but his family are by now living at Clifford Street in Southampton.

He appeared on the 1910 US census as a steward serving aboard the St Louis. When the 1911 UK census was conducted Hubert was described as an unmarried ship's steward and still living with his family, now at 11 St Andrew's Road, Southampton. His mother was now a widow, his father having died in 1907 aged 71. Also present was his married sister Ida Petersen and her two sons Norman (b. 1896) and Cecil (b. 1902). His sister Laura had emigrated around 1910 and lived in Manhattan where she worked as a hotel waitress.

Hubert signed-on to the Titanic, on 4 April 1912, and gave his address as 11 St Andrew's Road, (Southampton). He stated that his previous ship had been the St. Louis and as a saloon steward he received monthly wages of £3, 15s.

Hubert Perriton died in the sinking. His body, if recovered, was never identified. The following death notice appeared in the Hampshire Independent:
