Ó Mainnín

Rev Patrick Woulfe

Ó MAINNÍN—IO Mannine, O Mannin, O Manynge, Mannin, Mannion, Manion, Manning, Mangin, (Mangan); 'descendant of Mainnín' (perhaps the same as Mainchín); the name of a Galway family who were formerly chiefs of Sodhan, a district nearly co-extensive with the barony of Tiaquin. Ó Mainnín, King of Sodhan, is mentioned in the Chronicon Scotorum as early as the year 1135, and the O Mainnins continued to form a distinct clan down to the time of James I. The chief resided at Menlough Castle, in the parish of Killascobe. In 1617, Hugh O'Mannin surrendered his estates to the king and received them back by letters patent. The whole property was confiscated after the Cromwellian wars, but a small portion of it was restored under the Act of Settlement in 1676. The name is still common in Galway and Roscommon, and has spread into other parts of Ireland. It is sometimes pronounced Ó Maingín and so incorrectly anglicised Mangin and Mangan.
