Granuaile

The Old Irish form of Grace, from "Gráinne" (itself possibly related to "grán", grain or sun) combined with the epithet "Mhaol" (bald, or of the cropped hair). Granuaile (Grace O'Malley, c. 1530–1603) was the legendary Irish chieftain and pirate queen of Connacht who commanded a fleet of ships, led her clan in armed rebellion against English expansion, and famously negotiated face-to-face with Queen Elizabeth I.

Dagda

From the Old Irish "Dagda" meaning "the Good God" from "dag" (good, noble) and "día" (god).

Fearghal

From the Old Irish "Fearghall" or "Fergal", composed of "fear" (man) and "gal" (valour, ferocity), meaning "man of valour" or "super-valour". The name was borne by Fergal mac Máele Dúin, King of Ireland from 710 to 722 AD, and by Saint Fergal (Virgilius) of Salzburg — an Irish monk who became Bishop of Salzburg and controversially taught that the Earth was spherical, centuries before it was widely accepted in Europe.

Derived from the Old Irish "rón" meaning "seal" combined with the diminutive suffix "-án" — giving the meaning "little seal" or "young seal".
