Baron Galtrim was an Irish feudal barony: in other words, the holder of the barony, which was hereditary in the Hussey family, was entitled to style himself Lord Galtrim, but was not entitled as of right to sit in the Irish House of Lords, although at least two holders of the title did receive a summons to sit in Parliament, and a third sat in the House of Commons. The title was created in the late fourteenth century by summons to Parliament. Use of the title lapsed in the early nineteenth century: from then on the former Lord Galtrim was usually referred to simply as "Mr. Hussey of Rathkenny" (Rathkenny was the Hussey family home in County Meath from the early fifteenth century).
