i.e. the descendants of Eoghan Mor, the eldest son of Olioll Olum. Of this tribe the Mac Carthys, though not the senior descendants of Eoghan Mor, were in latter times by far the most powerful and distinguished. It is remarkable that, at the period when this tract was written, O'Kelly should not be considered more closely linked with his neighbours the Dal Cais, than with the Eoghanachts, who were far from his neighbourhood, being then principally settled in the present counties of Cork, Kerry, and Limerick. And yet, the Dal Cais, that is, the O'Briens and their correlatives, in Thomond, were as often kings of Cashel as the Eoghanachts.
