Character Name

Sadhbh

Meaning — 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.·Old Irish origin·Female·SIVE (rhymes with "five")

Sadhbh Sadhbh carries the quality of gentleness under siege — a sweetness that the world repeatedly tries to transform into something lesser, and a resilience that preserves the essential self through those transformations. Characters with this name are often at the centre of stories about love separated by circumstance, about the cost exacted by those who cannot bear to see goodness flourish freely.

Brigid

Derived from the Old Irish "Brigit" or "Bríg", meaning "exalted one" or "the high one", from a Proto-Celtic root "briganti" meaning "high, lofty, the exalted one". Brigid was one of the most important goddesses of pre-Christian Ireland, associated with poetry, healing, smithcraft, and the hearth fire. The Christianised Saint Brigid of Kildare (c. 451–525) became one of Ireland's three patron saints.

Orla

Anglicised form of the Irish "Orfhlaith" (also spelled Orlaith), meaning "golden princess" or "golden sovereign", from the Old Irish "ór" (gold) and "flaith" (sovereignty, princess). The name was borne by several early Irish noblewomen, including a sister of Brian Boru — the High King of Ireland who defeated the Vikings at the Battle of Clontarf in 1014.

Doireann

Derived from the Old Irish "doire" meaning "oak grove" (a sacred space in Celtic tradition) combined with a suffix — giving the meaning "daughter of the oak grove" or "she of the sacred grove". The oak was the most sacred tree in Celtic religion, associated with druids and the divine, making this name deeply rooted in pre-Christian Irish spirituality.

Finn

An anglicised form of the Old Irish "Fionn", meaning "white", "fair", or "bright". The name is inseparable from the legendary figure of Fionn mac Cumhaill (Finn MacCool), the mythological hunter-warrior who led the Fianna — an elite band of warriors — whose exploits form the Fenian Cycle, one of the four great cycles of Irish mythology. According to legend, Finn gained supernatural wisdom by accidentally tasting the Salmon of Knowledge.

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.

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.
