Gilla na Naemh Crom Ó Seachnasaigh

Gilla na Naemh Crom Ó Seachnasaigh (died 1224) was an Irish Chief of the Name.

Ó Seachnasaigh was lord of Cenél Áeda na hEchtge, but is only recorded in the Irish annals towards the end of his era.

• 1222: Gilla Mo Choinni Ó Cahill, Lord of Kinelea East and West, was slain by Shaughnessy, the son of Gilla na Naemh Crom Ó Seachnasaigh, after having been betrayed by his own people.
• 1223: Seachnasaigh Ó Seachnasaigh, the son of Gilla na Naemh Ó Seachnasaigh, was slain by the Clann-Cuilen, a deed by which the Bachal mor of St. Colman, of Kilmacduagh was profaned.
• 1224. Gilla na Naemh Crom Ó Seachnasaigh, Lord of the Western half of Kinelea of Echtge, died.

Only three more Ó Seachnasaigh's would be named in the annals before the 16th century (1240, 1403, 1408), none of them chiefs. Thus the succession of the lordship is unclear till c. 1533.
