Ó Cléirigh (Seán) ... d. 1846
Seán (or John) Ó Cleirigh, Irish scribe who could probably claim descent from certain illustrious scholars of the Uí Chléirigh, even if his own testimony seems fuzzy and inconsistent. He appears to have had, perhaps inherited, an unknown number of Irish manuscripts written by or associated with Cú Choigcríche Ó Cléirigh, five of which he brought to Dublin in 1817.
