King Alfrid [Aldfrith] of Northumbria, for instance, is said to have partaken of Lismore's hospitality, and certainly Cormac of Cashel, Malachy and Celsus of Armagh and many others of the most distinguished of the Scots partook thereof.

This Evir-Allen was the mother of Oscar, Fingal's grandson, but she was not alive when Fingal went to Ireland to assist Cormac against the invading Norsemen, which forms the subject of the poem called Fingal, in six books.

Fingal went with a large army, utterly defeated Colculla "lord of Atha," and re-established Cormac in the sole possession of Ireland.
