Old Irish · “Derived from the Old Irish "Aífe", itself from the word "oíph" meaning "beauty" (modern Irish "aoibh").

The Christianised Saint Brigid of Kildare (c. 451–525) became one of Ireland's three patron saints.

Lugh

Derived from a Proto-Celtic root possibly meaning "light", "brightness", or related to the word for "oath". Lugh (also Lug) was one of the most important of the Tuatha Dé Danann in Irish mythology, associated with the sun, craftsmanship, skill, and warfare. He was known as "Lugh Lámhfhada" (Lugh of the Long Arm) for his mastery of every art, and the harvest festival Lughnasadh bears his name.

Lir

From the Old Irish name Ler or Lir meaning "sea" or "ocean". Lir is the Irish sea god, cognate with the Welsh Llŷr (father of Brân the Blessed). His most famous appearance in Irish mythology is as the father in the Children of Lir, whose four children are transformed into swans by their jealous stepmother for nine hundred years. The Children of Lir is one of the Three Sorrows of Irish Storytelling.

Cillian

Probably derived from the Old Irish "cell" meaning "church" combined with a diminutive suffix, giving the sense of "associated with the church" or "little church". The name was borne by the 7th-century Irish saint Killian of Würzburg, who evangelised in Franconia and was martyred there, spreading Irish Christianity across continental Europe.

Conn

From the Old Irish "conn" meaning "chief", "head", or "sense/wisdom". Conn of the Hundred Battles (Conn Céadchathach) was a legendary High King of Ireland and ancestor of the Connacht and Leinster dynasties.

In the Ulster Cycle, Nessa was the mother of King Conchobar mac Nessa — his name means literally "son of Nessa" — a woman of great political cunning who manipulated the hero Fergus mac Róich into surrendering his kingship to her son by agreeing to marry Fergus only on condition he let Conchobar reign for a year.

Aoibhinn

Derived from the Old Irish "aoibhinn" meaning "delightful", "pleasant", or "beautiful" — an intensified form of "aoibh" (radiance, beauty). The word is used in Irish to describe something deeply enjoyable or beautiful, and as a name it expresses pure delight in the bearer. The name is closely related to Aoife and Caoimhe in its root concepts of beauty and pleasantness.
