Aodh Ua Goirmghiallaigh, King of Partraige Cera, died 1206.
Ua Goirmghiallaigh was king of an Irish population-group called the Partraige, believed to be of pre-Gaelic origins.
Ua Goirmghiallaigh's branch of the Partraige were located around Lough Carra in what is now County Mayo, and have given their name to the parish of Partry and the Partry Mountains.
Ua Goirmghiallaigh is notable as almost the only member of the Partraige to occur in any of the extant Irish annals, which refer to his death by the Men of Cera in 1206.
One of their most famous members was the Irish Confederate, Patrick D'Arcy (1598–1668).
