To which lines O'Donovan adds the following notes:
"The O'Meachairs. The name of this family is now Anglicized O'Meagher, but more generally Meagher or Maher, without the prefix O'. Their territory of Ui-Cairin is now called Ikerrin, and is a barony in the present county of Tipperary.
"Bearnan Eile, i.e. the gapped mountain of Ely, now called in English the Devil's-Bit Mountain"—(Notes, page lxxxv., n. 71 and 72.)
6. In the Leabhar na-Ceart, edited by the same distinguished Irish antiquary, for the Celtic Society, in 1847, we find some additional evidence not only for the connexion of the O'Meachars with the territory of Ui-Cairin, but also for the royal descent to which they laid claim. It is thus that Leabhar-na-Ceart commemorates the tributes which were due to the king of Eile:—
"Eight steeds to the king of Eile, of the gold
Eight shields, eight swords are due,
Eight drinking-horns to be used at the feast,
Eight coats of mail in the day of bravery"—(pag. 79.)
To which verse O'Donovan adds the following note:—
"Eile. This was the name of a tribe and an extensive territory, all in the ancient Mumha or Munster. They derived the name from Eile, the seventh in descent from Cian, the son of Oilioll-Ollum ... The ancient Eile comprised the whole of Eile Ui-Chearbhail, which is now included in the King's County ... and also the baronies of Ikerrin and Elyogarty in the county of Tipperary.... Ikerrin and Elyogarty were detached from O'Chearbhail shortly after the English invasion, and added to Ormond, but the native chieftains O'Meachair, i.e. O'Meagher, and O'Fogartaigh, i.e. O'Fogarty, were left in possession".
