Character Name

Lasair

Meaning — From the Old Irish "lasair" meaning "flame" or "blaze". Saint Lasair was a 6th-century Irish saint, daughter of the king of Connacht, whose feast day is celebrated in March. The name is strikingly evocative — flame as a feminine quality, the brightness that illuminates and warms but can also consume. It belongs to the tradition of Irish nature-names that describe a quality of being rather than a social role.·Old Irish origin·Female·LAS-ir

The flame quality suggests brilliance that requires tending and direction: extraordinary heat and light that, undirected, becomes dangerous and that directed becomes transformative. A name for characters who change every situation they enter.

More Old Irish names

Conan

Derived from the Old Irish "cú" (hound, warrior) or from a root meaning "high" or "chief" — giving possible meanings of "little warrior" or "little high one". Conan mac Morna was a figure in the Fenian Cycle, a member of the Fianna known for his sharp tongue and comic boastfulness. The name also has Breton connections through Saint Conan and a lineage of Breton/Cornish rulers.

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.

Diarmait

The original Old Irish spelling of Diarmuid, from elements possibly meaning "without envy" from "di" (without) and "airmit" (jealousy or envy). Diarmait mac Cerbaill was the last High King of Ireland to hold the ancient pagan ceremony of the "Feis Temro" (Feast of Tara) around 560 AD. The name appears across Irish history and mythology and reflects the older, more austere orthographic tradition.

Sorcha

Derived from the Old Irish word "sorcha" meaning "brightness", "radiance", or "light". It shares the same root as the modern Irish adjective "sorch" meaning "clear" or "bright". Sorcha has been used as an Irish equivalent of Sarah or Clara in anglicised contexts, though it is entirely distinct in origin. The name has been popular in Ireland and Scotland for centuries.

Rónán

Derived from the Old Irish "rón" meaning "seal" combined with the diminutive suffix "-án" — giving the meaning "little seal" or "young seal". In Irish tradition, seals were often believed to be fallen angels or transformed humans (selkies), and the name carries overtones of the liminal space between the natural and supernatural worlds. Several Irish saints bore the name.

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.
