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.”
Declan
Old Irish · “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.”
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.”
Padraig
Irish · “The Irish form of Patrick, derived from the Latin "Patricius" meaning "nobleman" or "of noble birth", from "pater" (father). Saint Patrick (c. 385–461 AD), the patron saint of Ireland, was a Romano-British missionary who became the most celebrated figure in Irish Christianity. The Irish form Pádraig has been used in Ireland continuously since the early medieval period.”
Ruairi
Old Irish · “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.”

Cliona
“Possibly derived from Old Irish "clú" meaning "fame" or "renown" with a feminine suffix. Clíodhna (also spelled Clíona or Cliodhna) is a significant figure in Irish mythology — one of the three waves of Ireland and a queen of the sídhe (fairy mounds) of Munster. She was sometimes said to be the most beautiful woman in the world, ruling the otherworldly realm of Tír Tairngire.”
Fionnán
“Diminutive of Fionn, from Old Irish "fionn" (white, fair, blessed) with the suffix "-án" indicating smallness or affection — "little fair one" or "dear fair one". Saint Fionnán (also Finán) of Kinnitty was an Irish monastic saint. The diminutive form gives it a warmth and approachability that the full Fionn lacks, suggesting someone whose brightness invites rather than overawes.”
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.”
Rónán
“From the Old Irish "rón" meaning "seal" combined with the diminutive suffix "-án", giving the meaning "little seal" or "seal-like one". In Irish mythology and folklore, seals were often considered to be transformed humans — the selkie tradition — and Rónán figures in several tragic Irish tales, most notably the tale of Rónán mac Aed, a king whose jealous son falsely accuses his stepmother, leading to a catastrophe reminiscent of the Greek myth of Phaedra and Hippolytus.”
Eoin
“The Old Irish form of John, derived from the Latin Iohannes and ultimately from the Hebrew Yohanan meaning "God is gracious". Eoin entered Ireland through the early Christian Church and has remained in continuous use for over a thousand years. It is distinct from the later anglicised "Seán" (which came via Norman French) and is considered the more archaic, native form of the name in Irish.”
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.”
