Charlotte FitzRoy, Countess of Euston (née Lady Charlotte Maria Waldegrave; 11 October 1761 - 1 February 1808), was the wife of George FitzRoy, 4th Duke of Grafton. Although she is sometimes referred to as "Duchess of Grafton",[1] her husband did not inherit the dukedom until 1811, after his wife's death.
She was a daughter of James Waldegrave, 2nd Earl Waldegrave, and his wife, the former Maria Walpole, the granddaughter of Robert Walpole, first Prime Minister of Great Britain. Maria later became Duchess of Gloucester and Edinburgh through her marriage to Prince William Henry, a grandson of King George II.[2] The Prince became stepfather to Charlotte and her sisters in 1766, when he secretly married Maria at his house in Pall Mall. Charlotte's elder sister was Elizabeth Waldegrave, Countess Waldegrave, whose children inherited the earldom. Charlotte's younger sister, Horatia, married Lord Hugh Seymour.
She married the future Duke of Grafton on 16 November 1784 at Navestock, Essex, when he was styled Earl of Euston.[3] She was therefore known by the courtesy title Countess of Euston.
Their children were:

Charlotte FitzRoy died at her home in Lower Brook Street, London, aged 45,[5] of "a liver complaint and bilious fever", and was buried in the family vault. Her obituary described her as "an example of every thing amicable in woman".[6]
