The Three Collas (Modern Irish: Trí Cholla) were, according to medieval Irish legend and historical tradition, the fourth-century sons of Eochaid Doimlén, son of Cairbre Lifechair. Their names were: Cairell Colla Uais; Muiredach Colla Fo Chrí (also spelt Colla da Chrioch, or Fochrich); and Áed Colla Menn. Colla Uais ruled as High King of Ireland for four years.[1] Recent DNA analysis confirms the history of the Three Collas in fourth-century Ireland, but questions their descent from Eochaid Doimlén and Cairbre Lifechair.
