Harriett Sarah Mordaunt

Harriet Sarah, Lady Mordaunt (7 February 1848 – 9 May 1906[1]), formerly Harriet Moncreiffe, was the Scottish wife of an English baronet and Member of Parliament, Sir Charles Mordaunt. She was the respondent in a sensational divorce case in which the Prince of Wales (later King Edward VII) was embroiled and, after a counter-petition led to a finding of mental disorder, spent the remaining thirty-six years of her life initially in several privately rented houses, and then in various private lunatic asylums, finally ending her days in Sutton, Surrey.
