Percival Albert Blake was born on 16 October 1889 in Winchester, Hampshire, England and his birth was registered in the December quarter of that year. He was the son of Edwin Oscar Blake (1862-1942) and Clara Cartwright (1861-1942). His father and mother, who were natives of Winchester and Guildford, Surrey respectively, had married in 1885 and would have six children, three of whom would die in infancy.
Percival first appears on the 1891 census living at 15 Gramville (?) Place in St Peter, Cheesehill, Hampshire, his father working in the building trade. Listed also are his siblings Edwin Ernest (b. 1886) and Millicent May (b. 1891). The family have moved to 27 Dock Street, Southampton by the time of the 1901 census and have an addition, Reginald, born 1896. Percival isn't present at the time of the 1911 census, perhaps at sea, but his parents and sister Millicent are resident at 18 Endle Street, Southampton.
When Percival signed on to the Titanic in Southampton on 6 April 1912, he gave his address as 2 Floating Bridge Road, although his family were still resident at 18 Endle Street. He had transferred from the Olympic. As a trimmer he received monthly wages of £5 10s.
Percival survived the sinking of the Titanic, escaping in lifeboat 15.
Percival Blake, known as "Nunk" to family and friends never married. He died in Gosport, Hampshire in 1968.
