Eithne is an Irish feminine given name, derived from the Old Irish word 'Eithni', which means 'she who goes forth'. This name was borne by several figures in Irish mythology and history, including Eithne, a daughter of Cormac mac Airt, the legendary High King of Ireland. The name gained further prominence through the medieval poem 'The Wooing of Eithne' or 'Eithne and Midir', which tells the story of a love triangle between Eithne, her husband, and the bardic poet Midir.
"Eithne was given to five babies born in 2007."
