Long ago the Yeomen were attacked by the O'Connors and the O'Hartes. The O'Connors went one of the Yeomen and the O'Hartes on the other. At the end of the battle the Yeomen were beaten. The O'Connos the the O'Hartes cut the heads off their enemies and after this, that place was called [Tobar?] na gCeann.
