Note: She was not a daughter of king Cerball of Osraige (Ossory). The name of the father of Echrad has sometimes been erroneously give as Cerball, an error that is due to the fact that the name Cerball has sometimes been Anglicized as "Charles" (also erroneously). Thus, some have falsely "corrected" the name Carrlus (the middle Irish form of Charles) to Cerball, on the assumption that it had been incorrectly Anglicized. However, the name Carrlus is a genuine name that appears in the Irish sources from the ninth century on (probably as a borrowing from the Norse, or, less likely, in imitation of Charlemagne), and there is no need to make this false "correction" to the name of Echrad's father. The error that Echrad's father was Cerball of Osraige is apparently another blunder added to this original mistake. -- Stewart Baldwin (Edited)
