Oneilland West

Oneilland West (, the name of an ancient Gaelic district) is a barony in County Armagh, Northern Ireland. It is also called Clancann (Clann Chana), after the Mac Cana clan. It lies in the north of the county on the south-western shore of Lough Neagh and the border of County Tyrone. Oneilland West is bordered by five other baronies: Armagh to the west; Dungannon Middle to the north-west; Oneilland East to the north-east; Orior Lower to the south-east; and Kinelarty to the south.

History
Oneilland West along with Oneilland East used to form the barony and Plantation of Ulster precinct of Oneilland. When it was split in two, Oneilland West consisted of the barony west of the River Bann, corresponding to the ancient Irish districts of Oneilland and Clancann.

Mount Roe house is located in this barony. The Battle of the Diamond on 21 September 1795, which led to the foundation of the Orange Order, occurred within this barony at The Diamond crossroads.
