Henry Butler-Johnstone (28 August 1809 – 1 April 1879)[1] was a British Conservative Party politician, born Hon.
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.
[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.
