Circumstantial evidence
Lúrach mac Cuanach is the 6th-century patron of the eccesliastical parish, with the local parish church, St. Lurachs, named after him. Lúrach's family held a degree of political importance in the area, with seven descendants of Lúrach's father Cuanu being kings of Airgíalla. Circumstantial evidence places their center of power at "Ráth Lúraigh".
