William Holmes à Court, 3rd Baron Heytesbury

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

1. Margaret Elinor FitzHerbert (née Holmes à Court) (1888–1957), married in 1907 to 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]
2. William Leonard Holmes à Court (born and died 1889)

His sudden death at the age of 41 came as a shock, as he was thought to be in excellent health.^[3]

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.^[4] 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.^[5][1]
