High Quality Content by WIKIPEDIA articles! Archibald Brabazon Sparrow Acheson, 4th Earl of Gosford KP (2 August 1841 – 11 April 1922) was a British Peer. The son of Archibald Acheson, 3rd Earl of Gosford, he succeeded to the earldom upon the death of his father in 1864. Since there are two United Kingdom peerages subsumed in that Irish Earldom, he was entitled to an automatic seat in the House of Lords. He was Lord Lieutenant of Armagh from 1883 to 1920. Gosford died in London in 1922.
