Henry Butler-Johnstone (28 August 1809 – 1 April 1879)[1] was a British Conservative Party politician, born Hon. Henry Butler, a younger son of James Butler, 13th Baron Dunboyne. He later assumed the surname of Johnstone,[2] due to his marriage with Isabella Margaret Munro, daughter of Sir Alexander Munro and niece and heiress of General Johnstone of Corehead.
He was elected at the 1852 general election as a Member of Parliament (MP) for Canterbury,[3][4] but in 1853 the election was declared void on petition, and the writ was suspended until 1854.[4]
Johnstone regained the seat at the 1857 general election,[4][5] was re-elected in 1859[4][6] and resigned from the House of Commons[4] on 27 January 1862 by the procedural device of accepting appointment as Steward of the Manor of Northstead.[7] At the resulting by-election on 6 March 1862, his son Henry Munro-Butler-Johnstone[2] was elected to succeed him as MP for Canterbury.[4]
Butler-Johnstone died on 1 April 1879 at his residence in Mayfair after a long illness.[8]
