Eithne Tháebfhota ("of the Long Side") was one of the daughters of High King of Ireland Cathaír Mór. Irish mythology describes her as the queen of two kings of different generations.
Queen of Ireland In most Old Irish writing, she is the wife of Conn Cétchathach. Her marriage was thought beneficial to the kingdom; until her death the fields gave three harvests a year, showing that she was a form of the goddess of Sovereignty.
Esnada Tige Buchet In The Melodies of Buchet's House, Eithne was in fosterage to Buchet when her numerous brothers came and stole his cattleherds. Buchet forced to leave his house, with his wife and Eithne. They lived in a small hut, at the forest of Kells, when she met her future husband, Cormac mac Airt, Conn's grandson. She spends a night with him, to conceive Cairbre Lifechair.
Echtrae Cormaic In The Adventure of Cormac, she also appears to be Cormac's wife.
