Diarmuid Diarmuid is the name of an irresistibly charismatic man caught between competing loyalties — to his chief, his love, and his own honour. The name carries deep associations with doomed romance and masculine beauty, with an undertone of tragic inevitability. Characters named Diarmuid tend to be magnetically attractive, scrupulously honourable in their own terms, and ultimately destroyed by forces that their very virtues set in motion.

More Old Irish names

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.

Aoibhe

From the Old Irish "aoibh" meaning "beauty", "radiance", or "pleasantness". Aoibhe is a variant of Aoife and shares the same etymological root, but is treated as a distinct name in Irish usage. The name belongs to the same cluster of Irish feminine names derived from concepts of brightness and beauty that include Niamh and Aoife, and has been in use in Ireland since the early medieval period.

Cian

From the Old Irish "cian" meaning "ancient", "enduring", or "of long standing". In Irish mythology, Cian was a figure of the Tuatha Dé Danann, father of the sun god Lugh by the Fomorian princess Ethniu. The name has been borne by several early Irish saints and kings, lending it a lineage stretching back to the earliest strata of Irish recorded history.

Eoin

The Old Irish form of John, derived from the Latin Iohannes and ultimately from the Hebrew Yohanan meaning "God is gracious". Eoin entered Ireland through the early Christian Church and has remained in continuous use for over a thousand years. It is distinct from the later anglicised "Seán" (which came via Norman French) and is considered the more archaic, native form of the name in Irish.

Méabh

The older spelling form of Maeve, derived from Old Irish "medb" meaning "she who intoxicates" or "mead" — cognate with the drink associated with sovereignty. Méabh is the great warrior queen of Connacht in the Ulster Cycle, the driving force behind the Táin Bó Cúailnge (Cattle Raid of Cooley). She is one of the most powerful and complex female figures in all Celtic mythology — a queen who commands armies, takes and dismisses husbands at will, and matches her political authority with personal sovereignty.

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.
