The Conmaicne Mara ( ; Modern ) were an early people of Ireland. Their tuath was located in the extreme west of County Galway, Ireland, giving their name to Connemara, an anglicised form of Conmhaicne Mara.
The Conmaicne were a people of early Ireland, perhaps related to the Laigin, who dispersed to various parts of Ireland. They settled in Connacht and Longford, giving their name to several Conmaicne territories. Other branches of the Conmaicne located in County Galway included the Conmaicne Dúin Móir and the Conmaicne Cúile Tolad.
Conmaicne Mara comprised all of the barony of Ballynahinch and the civil parish of Inishbofin, which is in the barony of Murrisk. The territory contains the five civil parishes of Ballynakill (), Ballindoon, Moyrus (), Omey () and Inishbofin (). The territory contains the five Catholic parishes of (Clifden, Omey & Ballindoon), (Carna), (Roundstone), (Ballynakill) and ( Inishbofin).
The area of County Galway in which Connemara lies is known as Iar Connacht i.e. the portion of County Galway west of Lough Corrib and a small piece of County Mayo. The parish of Kilconickny, which means "church of the Conmaicne"is located west of the town of Loughrea.
The chiefs of the Conmaicne Mara were the OâÂÂKealys, and their cadets were the MacConneelys, OâÂÂDevaneys, and OâÂÂClohertys, with the OâÂÂFalons [Folan] as their hereditary brehons. The OâÂÂKealys relocated to Ui Oirbsen, but they were to find themselves imposed upon again after just a few decades. The MacConneelys stayed in their home at Ballyconneely Peninsula, but soon found themselves neighbors of the OâÂÂFlahertys.
A court inquisition in 1607 includes the following as leading chiefs of name in the barony of Ballynahinch: OâÂÂFlaherty of Bunowen, MacConroy, MacConnor, MacDonough, OâÂÂDuan, OâÂÂLee, and MacConneely. MacConnor and MacDonough, are chiefs of branches that separated from the OâÂÂFlahertys, while the two after that, OâÂÂDuan and OâÂÂLee, headed old followers of that family. The MacConneelys were the eldest cadets of the OâÂÂKealys of Conmaicne Mara.
