Fionn

Old Irish · “Derived from the Old Irish "find" meaning "white", "fair", or "fair-haired". It is one of the most celebrated names in Irish mythology as the given name of Fionn mac Cumhaill, the legendary leader of the Fianna warrior band. Fionn gained supernatural wisdom as a boy by accidentally tasting the Salmon of Knowledge, and he became Ireland's greatest hero and protector.”

Fergus

Old Irish · “Derived from the Old Irish elements "fer" meaning "man" and "guss" meaning "vigour", "strength", or "force" — together meaning "man of vigour" or "strong man". The name was borne by several early rulers of Ireland and Dál Riata, and most notably by the hero Fergus mac Róich of the Ulster Cycle, a warrior of extraordinary physical power and loyal character.”

Cormac

Old Irish · “Derived from the Old Irish "corb" meaning "chariot" (or possibly "raven") and "mac" meaning "son" — giving the meaning "son of the chariot" or possibly "charioteer's son". The name was borne by the legendary High King Cormac mac Airt, considered one of Ireland's greatest and wisest kings, whose court at Tara became associated with an idealised golden age of justice and prosperity.”

Conor

Irish · “Anglicised form of the Irish "Conchobar" or "Conchobhar", derived from "con" (dog or wolf, used as an honorific for a great warrior) and "cobhar" (desiring or loving) — together possibly meaning "lover of hounds" or "wolf-lover". Conchobar mac Nessa was the king of Ulster in the Ulster Cycle of Irish mythology, the lord who ruled over the great warriors including Cúchulainn.”

Lír

“From the Old Irish "lir" meaning "sea" or possibly related to the Proto-Celtic sea deity. Lír (or Lir) was the Irish god of the sea and father of the four children who were transformed into swans in the most beloved of Irish mythological tales. The related figure Llyr appears in Welsh mythology in the Mabinogion, and scholars identify him with the legendary British king whose story Shakespeare transformed into King Lear.”

Declan

“Possibly derived from the Old Irish "Deaglán" or "Diaglán", with the most accepted interpretation being "full of goodness" or "man of prayer", though an alternate reading suggests "full of God" from "Dia" (God). Saint Declan of Ardmore was one of the earliest Christian missionaries in Ireland, predating Saint Patrick, and his name has been honoured in the Munster province for over fifteen centuries.”

Donal

“From the Old Irish "Domhnall", composed of the Celtic elements "dubno" (world) and "val" (rule), meaning "ruler of the world". This was an extremely common name among Irish and Scottish kings and chieftains — multiple High Kings of Ireland bore the name, as did numerous Scottish monarchs and clan chiefs. The name projects both worldly authority and a specifically Celtic conception of kingship as stewardship of the land.”

Ruairi

“Derived from the Old Irish "Ruaidhri" composed of "ruadh" meaning "red" or "red-haired" and "rí" meaning "king" — together meaning "red king" or "red-haired king". The name was popular among Irish and Scottish nobility. Ruaidrí Ua Conchobair (died 1198) was the last High King of Ireland before the Norman invasion, making the name historically resonant with the final era of Gaelic sovereignty.”

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.”

Niamh

“Derived from the Old Irish word "niamh" meaning "bright" or "radiant". The name belongs to one of the most celebrated figures of Irish mythology, Niamh of the Golden Hair, a princess of Tír na nÓg (the Land of Eternal Youth) who fell in love with the poet-warrior Oisín and carried him away on her white horse across the sea.”
