Lua error in package.lua at line 80: module 'strict' not found. Ó Seachnasaigh, O'Shaughnessy, collectively Uí Sheachnasaigh, clan name Cinél nAedha na hEchtghe, is a family surname of Irish origin. The name is found primarily in County Galway and County Limerick. The town of Gort, Ireland, was the main residence of the family since at least the time of their ancestor, King Guaire Aidne mac Colmáin of the Uí Fiachrach Aidhne dynasty.

History

Up until the late 17th century the Ó Seachnasaigh's held the sub district of Uí Fiachrach Aidhne known as Cenél Áeda na hEchtge (modern Irish, Cinéal nAedha na hEchtghe) meaning "kindred of Aedh of the Slieve Aughty", which was also their clan name. Cinéal nAedha na hEchtghe / Kinelea consisted roughly of the civil parishes of Beagh, Kilmacduagh and Kiltartan and also parts of the civil parishes of Kibeacanty and Kilthomas. Their closest related kinsmen were the Ó Cathail / O Cahill clan, originally chiefs of eastern Kinelea, and the other clans of Uí Fhiachrach Aidhne the most prominent of which were the Ó hEidhin / O Hynes, Ó Cléirigh / O Cleary and Mac Giolla Cheallaigh / Kilkelly septs. Up until the mid 17th century the O'Hynes clan were still styled lords of Uí Fhiachrach Aidhne even though the Ó Seachnasaigh's had become more powerful than their kinsmen during this century. In the 1690s Captain Roger O'Shaughnessy had his lands confiscated for supporting the Jacobite cause against William of Orange with the lands going to Sir Thomas Prendergast, 1st Baronet. A legal battle raged on into the first half of the 18th century between the Ó Seachnasaigh and the Prendergasts, the family who were granted the lands, with the Ó Seachnasaigh eventually losing the case. The senior line of the Ó Seachnasaigh's may have died out in the 1780s.

O'Shaughnessy Castles include- Gort Castle, Fiddaun Castle, Ardnamullivan Castle, Newtown Castle, Derryowen, which is just inside the County Clare border, Ballymulfaig, and a castle on one of the islands in Lough Cutra. According to a list naming the castles of County Galway and their owners, drawn up in 1574 by the English administration in Ireland, Islandmore Castle, now known as Thoor Ballylee, is listed as been owned by a John O'Shaughnessy.

The last "de facto" Ó Seachnasaigh lord of Kinelea died at Gort after returning home from the Battle of Aughrim on 12 July 1691. Thousands of bearers of the name still survive both in their homeland and further abroad.

Notes

Some with relation to the O'Shaughnessy clan may spell it O'Shaughnessey or Shaughnessy. This change probably occurred when the family moved to the United States due to the potato famine.
