Eochaid Feidlech

A king of Tara. Eochaid Feidlech was better known because of his children, particularly his daughters. His consort may have been Crucaha, who was the mother of Medb (Maeve). Among his other daughters were Clothra, Eithne, Ele and Mugain. His sons included Furbaide and the triplets – Bres, Lothar and Nar. But the triplets were known collectively as Tri Finn Emna (or just Finn Emna, which is the Three Finns of Emain Macha.

Each one of his daughters was married to Conchobar Mac Nessa, king of Ulster, including Medb.

Trouble erupted in his family when Eochaid's wife left Tara, taking the Finn Emna with her to Emain Macha. Conchobar encouraged the Finn Emna to rebel against their own father. The Finn Emna gathered an army and tried to enlist aid from their sister, Clothra, who was queen of Connacht at this time. She refused to aid them, but Clothra did sleep with each of her brothers, and she became the mother of Lugaid Riab nDerg. Lugaid was born with two strange red lines; one line ran across his body, just under his shoulders, and the other ran across his belly. The three divisions indicated that he had three biological fathers.

In the fighting, Lothar managed to strike with a sling stone and knocked his father senseless, but the war still went against the Finn Emna, because the Ulster captured them and decapitated the three brothers. Eochaid Feidlech died from sorrow at the loss of his rebellious sons.

Clothra did not only commit incest with her three brothers. Later, she also slept with their son. Clothra conceived another son, Crimthann Nia Nair, through her incestuous union with Lugaid Riab nDerg.

Clothra was later a wife of Conchobar. Her sister Medb murdered her while Clothra was pregnant with Conchobar's child. The child was saved, and he was named Furbaide Ferbend. Furbaide would later avenge his mother's death by killing his aunt.
