Admiral Sir William Edmonstone, 4th Baronet CB, DL (29 January 1810 – 18 February 1888), also 14th of Duntreath, was a British naval commander, courtier and Conservative politician.
[1] Born at Hampton, Edmonstone joined the Royal Navy in his teenage years, serving as a midshipman on the frigate HMS Sybelle and was subsequently promoted Commodore.
On return from naval service off West Africa he was made an Aide-de-Camp to Queen Victoria and appointed a Companion of the Order of the Bath (CB).
He was promoted Rear-Admiral on 3 July 1869, the day before he retired from the Royal Navy, a common practice at that time.
[4] Edmonstone married Mary Elizabeth Parsons (Newburn, Fife, 21 June 1823 – Edinburgh, Lothian, 11 August 1902), daughter of Lieutenant-Colonel Parsons, on 13 July 1841 at Zakynthos, Greece, who was resident on the island of Zante, at a time when the Ionian Islands were a British Protectorate.
