Ordnance Survey Letters by John O'Donovan and Eugene Curry, 1839

Part II. Letters and Extracts relative to Ancient Territories of Thomond, 1841

VIII. Ui Caisin or Ogashin

This is the name of the original Territory of the Mac Namaras and their dependents and is only their original tribe name transferred to the country. Its more original name was Magh Adhair, signifying the Plain of Adhar, and appellation which it received from Adhar, the Firbolg, who possessed this plain in the first Century. See my letter on the Parish of Cloney.

The exact extent of the original country of this tribe is preserved in the ecclesiastical division called the Deanery of Ogashin, in which the following Parishes are contained according to the Liber Regalis Visitationis.

1. Quin (sic hodie)
2. Tullogh (hodie Tulla)
3. Clonee (hodie Cloney)
4. Deury (Dowry)
5. Kilraghtis (sic hodie)
6. Kiltolagh (now included in Inchicronan)
7. Templemaley (sic hodie)
8. Inchicronan (sic hodie)
9. Kilmori-na-gall (hodie Kilmurry & Kilmurry-na-gall).

It appears from Magrath’s Wars of Thomond that this was the original Country of the Mac Namaras, but after the year 1318 when the Hy-Bloid were defeated by the descendants of Torlogh O’Brien aided by the Mac Namaras, the latter got possession of nearly the entire of that part of the County of Clare lying to the east of the River Fergus and shortly after this period this tract was divided into two parts between two rival of Chiefs of the Mac Namaras. One of these divisions was called Clann Oirthearach Choileain (east) and its Chief Mac Namara Fionn, and the other Clann Iartharach Choileain and its Chief Mac Namara Reagh. The description of the County of Clare often already referred to as preserved in the Library of Trinity College places the following Parishes and Castles in the County of the Western Mac Namara which was called the Barony of Dangan in the reign of Queen Elizabeth.

“The Barony of Dangan conteyninge West Mac Namara’s Country, and is in ploughlands (plowghlands) after like rate XVIII. Shane Mac Namara Chief in the same.”

This Territory of the Western Mac Nemara swallowed up all Tradree which is a district of great celebrity which belonged first, according to O’Heerin, to O’Neill, a family of the Hy-Bloid. The name of this Territory is still known in the County, but the natives do not agree about the extent, some saying that Tradree comprises seven Parishes, and others that it contains but two Parishes. All however agree that this Territory lies between the River of Bunratty and the Fergus. But whatever may be the limits assigned to this Territory by Oral tradition, there can be no doubt that its original extent is preserved in that of the ecclesiastical division called the Deanery of Tradree, which comprises the following Parishes, according to the Liber Regalis Visitationis.

1. Tomfinlogh (sic hodie)
2. Killanasulagh (Killonasoolagh)
3. Kilmaleery (sic hodie)
4. Kilcorney (sic hodie)

From these lists it appears that the entire of the Baronies of Upper and Lower Tullagh and Upper and Lower Bunratty were included in the Countries of two Mac Namaras in the reign of Queen Elizabeth.

The following notices of the Territories of Hy-Caisin, and Clann Choileain occur in the Annals of the Four Masters:-

Before the Mac Namaras had driven out the Hy-Bloid their own Territory comprised only that Tract which is called Hy-Caisin, of which we have given the exact extent already, and the remaining part of the eastern half of the County was divided into several Territories among petty Chieftains of the tribe of Blod. These Territories [are listed in the following chapters].
