Henry Vivien Pierpont Conyngham, 8th Marquess Conyngham (born 25 May 1951), styled Viscount Slane until 1974 then Earl of Mount Charles from 1974 until 2009 and predominantly known as Lord Mount Charles, is an Anglo-Irish aristocrat who is best known for the rock concerts that he organises at his stately home Slane Castle, and for his column in the Irish Daily Mirror under the byline "Lord Henry".
He succeeded his father in the marquessate of Conyngham and other hereditary peerages in March 2009 but, notably in Ireland, he is still frequently referred to as "Lord Mount Charles", his former courtesy title.
Lord Conyngham and his wife, born Iona Grimston, divide their time between Beauparc House [3][4] and Slane Castle in County Meath; the latter was the family's principal ancestral seat until it was badly damaged by fire in 1991, but has since been restored.
