Eoghan Ó Donnghaile (Owen O'Donnelly) (fl.
Eugene O'Curry wrote of Ó Donnghaile in his Manners and Customs , saying that: "About 1680 a controversy sprang up among some of the bards of Ulster as to what race by ancient right belonged the armorial bearing of Ulster – the Red Hand – belonged.
Eoghan Ó Donnghaile took part in the controversy and claimed the Red Hand for the O'Neills of Tyrone."
Robin Flower believed that Ó Donnghaile was a member of the bardic family that had fostered Séan 'an díomais' Ó Néill (Shane O'Neill), and there is a lament for Shane – Ceist ar eolchibh iath Éireann/A question for the learned of Ireland ... – attributed to Ó Donnghaile.
Seosamh Ó Dufaigh held that he may be identical with the Eoghan Ó Donnghaile listed in the 1704 registration of clergy for the parish of Armagh, a priest and the author of Comhairle Mhic Clámha, and Mo choin do theacht Fheidhlime ... Ó Dufaigh sees the latter as salutation to his kinsman, Pádraig Ó Donnghaile, also known as Feilim Brady, The Bard of Armagh.
