Richard Handcock, 4th Baron Castlemaine (25 July 1826 – 26 April 1892),[1] styled The Honourable from 1840 to 1869, was an Irish peer.[2]
Born at Athlone, he was the oldest son of Richard Handcock, 3rd Baron Castlemaine and his wife Margaret Harris, daughter of Michael Harris.[3] In 1869, he succeeded his father as baron.[4] Handcock entered the British Army as ensign in 1844, was promoted to lieutenant two years later and served eventually as captain of the 41st (Welsh) Regiment of Foot from 1852.[5] In 1874, he was elected an Irish representative peer to the House of Lords.[6] A former Deputy Lieutenant of that county,[4] he was appointed Lord Lieutenant of Westmeath in 1889, a post he held until his death in 1892.[7]
On 10 February 1857, he married Hon. Louisa Matilda Harris, only daughter of William Harris, 2nd Baron Harris at Holy Trinity Brompton Church.[3] They had five daughters and three sons.[3] Handcock died from heart disease at Moydrum Castle[3] and was succeeded in the barony successively by his second son Albert and his third son Robert.[1]
