William Holmes à Court, 3rd Baron Heytesbury

William Frederick Holmes à Court, 3rd Baron Heytesbury (25 June 1862–15 August 1903) was a British peer and landowner in Wiltshire, a member of the House of Lords from 1891 until his death.

He was the elder son of William Leonard Holmes à Court (1835–1885) and his wife Isabella Sophia, a daughter of the Reverend Richard à Court Beadon,^[1] whose mother, Annabella à Court (1781–1866) had been a daughter of Sir William à Court, 1st Baronet.^[2]

On 21 April 1891, he succeeded his grandfather William à Court-Holmes as Baron Heytesbury (1828) and as a Baronet (1795). He was a Justice of the Peace for Wiltshire.^[1]

On 19 November 1887, he married Margaret Anna Harman, daughter of J. Nixon Harman, and they had two children:^[1]

• Margaret Elinor Holmes à Court (1888–1957)
• William Leonard Holmes à Court (born and died 1889).

Heytesbury's entry in Who's Who 1903 said he "owned about 13,400 acres" and lived at Heytesbury, Wiltshire, and Westover, Newport, Isle of Wight.^[3] He died in 1903, at Heytesbury House, and since 1901 had been master of the South and West Wilts Hunt. He was succeeded by his younger brother, Leonard Holmes à Court.^[4][1] His sudden death at the age of 41 came as a shock, as he was thought to be in excellent health.^[5]

In 1907, Heytesbury's daughter Margaret Elinor married Henry Edward FitzHerbert, a younger son of Sir Richard FitzHerbert, 5th Baronet, who later became a Church of England clergyman. They had four daughters and three sons, including Sir John Richard Frederick FitzHerbert, 8th Baronet (1913–1989), who inherited the Tissington Hall estate in 1963.^[1]
