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.

The name carries deep associations with the bardic tradition of Celtic Ireland and was borne by numerous kings, saints, and mythological figures throughout Irish history. Its anglicised forms — Thaddeus, Timothy, Teague — spread widely through the Irish diaspora, though none capture the full resonance of the original.”
Íde
“From the Old Irish "íde" possibly meaning "thirst" (for goodness or knowledge) or from an earlier root meaning "prosperity". Saint Íde (also Ita or Mide) of Killeedy was a 6th-century abbess and saint known as the "foster mother of the saints of Ireland", who according to legend fostered the young Saint Brendan and other monastic leaders. She is one of the most important female saints in the Irish tradition, whose monastic community in County Limerick became a centre of education and spiritual formation.”
Etain
“From the Old Irish "Étaín", possibly related to "ét" (jealousy) or to a root meaning "zeal" or "passion". Étaín is one of the most beautiful heroines of Irish mythology, the subject of the tale "The Wooing of Étaín" (Tochmarc Étaíne) — a woman transformed by a jealous rival into a fly and later reincarnated, living multiple lives without memory of her previous existence until her husband Midhir reclaims her from the human king she has become.”
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.”
Caoilfhinn
“Compound Old Irish name from "caol" (slender, narrow) and "fionn" (white, fair, blessed). The name combines physical grace with the light-filled beauty implied by "fionn". It is an authentically traditional Irish name that represents the layered compound structure common in early medieval Irish personal naming. Several saints and noblewomen in medieval Irish records bear this name.”
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.”
