Eadaion is in Origin.

Eadaion is a rare Anglicized respelling of the Irish Gaelic name Éadaoin, the modern form of Old Irish Étaín, borne by the heroine of the medieval saga Tochmarc Étaíne. The myth links the name to themes of beauty, transformation, and enduring love, which helped sustain its quiet use in Gaelic tradition and fueled its 20th-century revival in Ireland. Outside Ireland, Eadaion remains uncommon but is sometimes chosen by parents seeking a distinctive Celtic heritage choice.

Meaning is debated: some scholars derive Étaín from Old Irish ét “jealousy, passion” with the diminutive suffix -án; others view it as uncertain or pre-Gaelic, so symbolic associations often stand in for a gloss. Established variants and anglicizations include Étaín, Éadaoin, Eadaoin, Aideen, and Etain; rarer modern spellings such as Aedine also occur. Eadaion fits with modern Irish revival names while preserving a deep mythic pedigree.
