Chaloner was the son of
Richard Penruddocke Long, an MP from 1859 to 1868, and younger brother of
The 1st Viscount Long. His family owned
Rood Ashton House in Wiltshire and had lived in the county since the end of the 14th century. Chaloner's maternal grandfather was
William Dick, a member for
Wicklow from 1852 to 1880. In 1888, he assumed the surname of Chaloner by royal licence in accordance with the will of his maternal great-uncle Admiral Thomas Chaloner, who had inherited
Gisborough Hall and the Gisborough estate in North Yorkshire through his mother, a descendant of
Robert de Brus. Chaloner was educated at Winchester College and the
Royal Military College,
Sandhurst, after which he was commissioned a
second lieutenant in the
3rd Hussars on 30 January 1878. He served in the
Second Anglo-Afghan War 1879–1880, and was promoted to
lieutenant on 1 July 1881. Promotion to
captain came on 1 July 1887, followed by
brevet appointments as
major and
lieutenant-colonel on 10 February 1894. He transferred to the
Reserve of Officers, and became lieutenant-colonel in command of the 1st
Wiltshire Volunteer Rifles. Following the outbreak of the
Second Boer War in October 1899, many volunteer officers were commissioned as part of the
Imperial Yeomanry which was created in December 1899. Chaloner was appointed in command of the 1st (Wiltshire) Company of the 1st Battalion, and left
Liverpool for
South Africa on the
SS Cymric in March 1900. Chaloner was first elected to
Parliament for
Westbury in the
1895 general election. At the next general election in
1900, he was defeated by the
Liberal candidate
John Fuller. In the
January 1910 general election, Chaloner was re-elected to Parliament succeeding the Liberal MP
J. E. B. Seely in the constituency of
Liverpool Abercromby. He retained this seat until 18 June 1917, when he was made
Steward of the Chiltern Hundreds, a post that expelled him from the Commons, thus effectively
resigning from the Commons. On 23 June 1917, he was made the
Baron Gisborough, of
Cleveland in the
County of York, and became a member of the
House of Lords. A
by-election was held in Liverpool Abercromby to replace him. Lord Gisborough died in 1938 in Cleveland, aged 81, and was succeeded in the barony by his second son,
Thomas. ==Family==
