More Old Irish names

Lugaid

Derived from the Old Irish god-name Lugh, with the suffix "-aid" making it a personal name in the human sphere. Lugaid was an extremely common name in early medieval Ireland — several kings and mythological figures bear it, including Lugaid mac Con, Lugaid Riab nDerg (of the red stripes, a legendary High King), and Lugaid mac Maic Con. The name carries the solar brightness of Lugh into a human register.

Oisín

Derived from the Old Irish "os" meaning "deer" combined with the diminutive suffix "-ín", giving the meaning "little deer" or "young fawn". In Irish mythology, Oisín was the greatest poet and warrior of the Fianna, son of the legendary hero Fionn mac Cumhaill. His mother Sadhbh had been transformed into a deer, and so the name carries a poetic link to his origins.

Sadhbh

From the Old Irish "sadb" meaning "sweet" or "goodly". In Irish mythology, Sadhbh is the mother of Oisín: she was transformed into a deer by the Dark Druid Fear Doirc and returned to human form when she entered the protection of Fionn mac Cumhaill. Their son Oisín ("little fawn") was born while she was again in deer form after she was recaptured. The name carries both gentleness and the tragedy of transformation.

Deirdre

The etymology is uncertain, but possible derivations include Old Irish "derdriu" meaning "sorrowful" or "broken-hearted", or alternatively related to a root meaning "wanderer" or "she who chatters". Deirdre is the tragic heroine of one of the Three Sorrows of Storytelling in Irish mythology — the tale of Deirdre of the Sorrows — whose beauty was prophesied to bring ruin to Ulster.

Aoife

Derived from the Old Irish "Aífe", itself from the word "oíph" meaning "beauty" (modern Irish "aoibh"). This ancient Irish name has been borne by several legendary figures, most notably a fierce warrior woman who engaged in single combat with the hero Cúchulainn, and a jealous queen in the tale of the Children of Lir who transformed her stepchildren into swans.

Aisling

From the Old Irish "aisling" or "aislinge" meaning "dream" or "vision". In Irish literary tradition, an aisling is a specific genre of poem in which a poet encounters a beautiful woman in a dream — the personification of Ireland — who laments the country's suffering under foreign rule and prophecies its liberation. The name thus carries the weight of an entire literary and political tradition within Irish culture.
