The Ó Dubhda story spans roughly 2,200 years – a figure rooted not in legend but in the named-king genealogies preserved in the Book of Lecan and corroborated by O’Donovan’s 1844 pedigree of the family. Our line reaches back to the kings of Uí Fiachrach Muaidhe in the centuries before Christianity took hold in Ireland, and forward through every century since.

We tell that story in five acts on the site.

Act I – Deep Ireland. The Iron Age and pre-Christian centuries: the founding kings, the lake-and-river kingdom of the lower Moy, the cosmology that placed Carn Amhalghaidh on Ben Buí as the centre of the world.

Act II – Fiachra and the Kings. The Christianisation of Connacht, the formal naming of Uí Fiachrach Muaidhe, the high-king dynasties that produced one of the most powerful clans of medieval Connacht.

Act III – Sea-Kings of the Moy. The medieval high-water mark: a clan that held the coast from Killala to Sligo Bay, built a wall of castles along the Moy, and controlled the rich Atlantic fisheries.

Act IV – Pressure and Dispossession. The Anglo-Norman incursion, the Tudor reconquest, the Cromwellian transplantation, and finally the Famine – the events that drove the Ó Dubhda off the lands they had held since the early medieval period.

Act V – Return and Revival. The diaspora, the slow recovery of memory, the formal revival of the clan as a living institution in the modern era.

Empires came. Empires went. The river kept flowing, and so did the family.
