Henry Agar, M.P.

Henry Agar's son, another James (1734-89) was made a peer as 1st Baron Clifden in 1776 and elevated to be 1st Viscount in 1781. He and his son, Henry, 2nd Viscount Clifden (1761-1836), were active in politics in both England and Ireland, but the 2nd Viscount largely left Ireland for England after taking a prominent part in the suppression of the 1798 rebellion in Ireland. In 1802, he inherited the GB peerage title of Baron Mendip on the death of his maternal uncle (whereupon he added Ellis to his surname), and also inherited his uncle’s house at Twickenham (Middx), Pope’s Villa, which he sold in 1807, buying Holdenby House in Northamptonshire from his father-in-law, the Duke of Marlborough, as a replacement English seat. He remodelled or rebuilt Gowran Castle in 1817-19, but it was probably not much used by the family in the early 19th century.

"1747 - Following the death of Henry Agar in 1746 his wife Ann offered for sale stock of Henry Agar decd, sheep, cattle horses, at Castle. Also colts & fillies got on mares by horses from England. Henry inherited the Gowran Castle estate from his father James in 1733. As a result of his marriage he acquired an interest in the Ellis family's Dublin property on the R. Liffey between Arran Quay and Phoenix Park; this property later passed into the Agar family. He died 18 November 1746. His widow married 2nd, 20 January 1753, George Dunbar of Co. Fermanagh, and died 14 April 1765; she was buried in Christ Church Cathedral, Dublin, 17 April 1765. Administration of her effects was granted by the Prerogative Court of Armagh to her second husband, 11 September 1765."
