Eidhean mac Cléireach

Who is Eidhean mac Cléireach?

Eidhean mac Cléireach, ancestor of the Ó hEidhin/Hynes family of County Galway, fl. 800.

Eidhean was a member of the dynasty of Uí Fiachrach Aidhne, and a descendant of Guaire Aidne mac Colmáin, Fiachrae mac Eochaid Mugmedon and thus distantly related to the dynasty of Uí Néill. His descendants ruled Aidhne for a time, most notably in the 1090s when Flaithbertaigh Ua Flaithbertaigh seized the kingship of Connacht and installed an Ó hEidhin as a puppett-king for a time.

Eidhean was a kinsman of a number of other men whose descendants also took their surnames from them, such as
