Ruaidrí Ó Gadhra


Ruaidrí Ó Gadhra, was an Irish king of Sliabh Lugha and Chief of the Name, died 1256.
During Ruaidrí's lifetime the territory of Sliabh Lugha was conquered by the Sheriff of Connacht, Jordan de Exeter, ancestor of the Clan Mac Siúrtáin. Sliabh Lugha would from this time become known as Tir Mac Síurtáin, in time becoming the barony of Gallen.
As a result of this, the Clan Ó Gadhra were forced north into Cuil Ui Fionn, which would become their new home.
The Annals of the Four Masters record a number of incidents concerning the Ó Gadhra family during Ruaidhri's reign:
In 1256, Ruaidhri was slain by David, son of Richard Cuisin, who was apparently of the family that would go on to produce Ádhamh Cúisín, a scribe and genealogist who lived c. 1400 and was a compiler of Leabhar Ua Maine.
Ruaidhri was succeeded by Ruaidri Ó Gadhra.
