Location of Dufferin, County Down, Northern Ireland.
|Sovereign state||United Kingdom|
Dufferin is a historic barony in County Down, Northern Ireland. It is on the south-east shore of Strangford Lough, and is bordered by three other baronies: Castlereagh Lower to the north; Castlereagh Upper to the west; and Lecale Lower to the south. Dufferin derives its name from the Irish [A]n Duibhthrian, meaning "the black third".)
Dufferin, along with the barony of Kinelarty and part of Castlereagh was at one time part of the territory of the Cenél Foghartaigh (Kinelarty), ruled by the Mac Artáin (MacCartan) sept. The Ó Labhradha (Lowry, Lavery) sept are also noted in Dufferin.
