Goll Mac Morna

Captain of the Fianna (rígfhéinnid) and chieftain of the Clan Morna. Goll was the brother of Conan (Mac Morna). Goll's real name was Aed, which means "Red".

Goll challenged Cumhaill for the leadership of the Fianna. Goll became captain of the Fianna after the death of Cumhaill and defeat of Clan Baiscne at the battle of Cnucha (Knock). Goll lost one of his eyes to Cumhaill in the battle. It was for this reason that he changed his name from Aed to Goll, which means "One-eyed".

Years later, Goll lost the captaincy to Cumhaill's son, when Finn became a young man.

Later, the Fianna split again during the reign of Cairbre. Goll and the Clan Morna sided with the high king. He led the Clan Morna against Clan Baiscne in the Battle of Gabhra.
