“From the Old Irish "muir" (sea) and "geal" (bright, white), meaning "bright as the sea" or "bright sea". The name appears in early Irish sources and belongs to the tradition of Irish feminine names formed from natural imagery — particularly the sea, which held enormous symbolic importance in a country surrounded by it. It represents the feminine form of the "sea" name cluster alongside Muireann and Muirenn.”
Áine
“Derived from the Old Irish "áine" meaning "brightness", "radiance", or "splendour", possibly related to "áin" meaning "joy".

She was the queen of the Munster fairies and was closely connected with the sun and the ripening of crops.”
Morrigan
“From the Old Irish "Mór Ríoghain" meaning "great queen" or possibly "phantom queen" (with "mór" as great or "mor" as related to "muir", sea). The Morrígan is one of the most significant and complex figures in Irish mythology — a triple goddess of fate, war, and sovereignty who appears as a raven, a wolf, a crow, and a beautiful woman. She confronts heroes at critical moments, testing their courage and foretelling death.”
Conn
“Derived from the Old Irish "conn" meaning "chief", "reason", "intelligence", or "head" — the same root that gives the modern Irish "ceann" (head). Conn of the Hundred Battles was one of the legendary High Kings of Ireland, ancestor of the Connachta dynasty, and the name was borne by numerous historical and legendary Irish rulers. It projects both intellectual authority and natural leadership.”
Lasair
“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.”
Niamh
“Derived from the Old Irish word "niamh" meaning "bright" or "radiant". The name belongs to one of the most celebrated figures of Irish mythology, Niamh of the Golden Hair, a princess of Tír na nÓg (the Land of Eternal Youth) who fell in love with the poet-warrior Oisín and carried him away on her white horse across the sea.”
