Mrs Charles Valentine Clarke was born as Ada Maria Winfield in Netley near Southampton, Hampshire, England on 14 December 1883.
She was the daughter of Menel 1 John Winfield (1852-1932) and Maria Gallon (1855-1943) who had married in 1878 in Hampshire. Her father, a general labourer was a native of Great Ponton, Lincolnshire whilst her mother was from Newcastle-upon-Tyne, Northumberland. The couple had five daughters: Mary Ann (b. 1879), Margaret Elizabeth (b. 1881), Ada Maria (b. 1884), Martha (b. 1885) and May (b. 1888).
The family appears on the 1891 census living at 13 Victoria Road, Netley, moving to 5 Arthur Terrace by the time of the 1901 census. Ada wasn't present with her family and was listed elsewhere as a servant (kitchen maid) at Rownhams House in Rownhams, Hampshire in the employ of a wealthy family.
She was married on 29 June 1908 to Charles Valentine Clarke (b. 1883), a dairyman and native of Cosham, Hampshire. The couple would have no children and appeared on the 1911 census living at Sea View on Solent Road, Drayton, Hampshire.
Ada and her husband boarded the Titanic at Southampton on 10 April 1912 as second class passengers (ticket number 2003 which cost £26) and their last address was Colaba, Grange Lane, Netley, the home of her parents. They were destined for San Francisco, California. She had a sister living at 142 Ox Point, Richmond, California.
Ada survived the sinking, escaping in lifeboat 14. Her husband died in the sinking.
Ada elected not to continue to San Francisco and returned to Britain on board the Celtic on 25 April 1912. She never remarried and remained close to her parents, later living with them at Mayarda on Archery Road, Woolston, Southampton. She died there on 8 February 1953 aged 69 and is buried in Holy Trinity churchyard, Weston Lane, Southampton.
