“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.”
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.”
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.”
Ciara
“Derived from the Old Irish "ciar" meaning "dark", "black", or "dark-haired". Saint Ciara of Kilkeary was a sixth-century Irish saint, and the name appears throughout early Irish ecclesiastical records. The meaning reflects an older Celtic aesthetic that prized dark colouring, and the same root gives the male name Ciarán, meaning "little dark one".”
Liadan
“From the Old Irish "líadan" meaning "grey lady" or "lady of the grey hair", from "lía" (grey) and the feminine suffix. Liadan is the protagonist of one of the most moving love stories in early Irish literature — the tale of Líadan and Cuirithir, two poets who fall in love but whose relationship is destroyed when Líadan takes holy vows, choosing religious devotion at the cost of human love. The surviving lament attributed to her is among the earliest and most beautiful poems in Old Irish.”
