Ada Annie Watney

[3] On 15 August 1889 at St Luke's Church, London, Ada Annie Nunn aged 21, "reputed to be a former ballet-dancer" had married 19-year-old Sherman Martin, the eldest son of the banker and socialite Bradley Martin, but when his parents found out some weeks later, they were "overwhelmed with mortification", and Ada was offered $10,00 to divorce.

[4] Martin relapsed and was sent to the Hartford Retreat for the Insane in March 1894, and after a few months was released apparently cured of his dipsomania, but died on 22 December 1894 in Baltimore after a very brief illness.

In the late 1890s they moved to 20 Charles Street, Mayfair, London, which became the family home.

[5] During the First World War, Ada turned part of the house into a nursing home for officers "furnished and equipped with every requirement of modern surgery, and fully staffed by trained sisters and nurses".

The latter was also used as a convalescent home for soldiers during the First World War, and in 1929 it was transferred by Ada, then a widow, to the Sisters of the Sacred Hearts of Jesus and Mary, who turned it into St Dominic's School, a "residential school for delicate boys".
