Baron of Dunsany
The title Baron of Dunsany or, more commonly, Lord Dunsany, is one of the oldest (1439 or 1461/2) dignities in the Peerage of Ireland, one of just a handful of 13th- to 15th-century titles still extant, having had 21 holders, of the Plunkett name, to date. Other surviving medieval baronies include Kerry (1223, now a subsidiary title of the Marquess of Lansdowne), Kingsale (1344, feudal barony 1223), Baron Louth (second creation, 1541), and Dunboyne (1541, feudal barony 1324).
