Here is an article from Irish Sword 1962 that I found in my Muintir Birn file. It mentions many of the names you guys are discussing: O DOMHNAILL’S CLAIM FOR MILITARY SERVICE By Colm O Lochainn In a list of the contents of MS. Rawlinson B 514* (from which source Fr. O’Kelleher edited Maghnus O Domhnaill’s “Life of Colum Cille”) the late E. C. Quiggin** printed a short passage in prose on “Military service due to O Domhnaill” taken, it is claimed, from the “old book of O Seingin of Ard Carne.”*** I here give my English translation with some notes on the peoples and territories mentioned. The extravagant claims made for O Domhnaill, Lord of Tir Cenaill, by the family chronicles were productive of bad blood and enmity between the overlords of the various northern kingdoms, and were prejudicial to any hopes of union within Ulster and between Ulster and Connacht. To claims such as these we may trace much of the jealousy, ill-will and bloodshed that marked Ulster history in the time of Seana an Diomais and later. “The standing claim for military service of O’Donnell on the province of Ulster is as follows:- “The equivalent of 40 men on Tir Chonaill; 60 on Clannaboy; 55 ½ on O Cathain; 60 on Cinel Moain; 40 per quarter year on O Floind; 40 on Mac Gilla Muire; 60 on Ui Eachach; 40 on the Oirtheara; the same amount on the Oaghialla; 40 on Fir Monach; 40 on the Fiachrach of Ardstraw;40 on Mac Cathmail; 12 on MagCana; 32 on Muuintir Birn; 6 of O Caragdin (?)e —An excerpt from the old book of O Seingin of Ardcarne.” The “old book of O Seingin” is not known to have survived. For the story of the chroniclers O Seingin and O Cleirigh see Father Paul Walsh “The O Cleirigh Family of Tin Connail,” p.2. The late Professor Eoin Mac Neil told me that the surname O Seingin has been anglicized “Skeffington,” though is S. Tyrone O Sgineadar is the surname anglicized “Skeffington.” The story says that the son of the last chronicler of the name died in 1382, but Fr. Walsh suggests 1342. The claim that Clannaboy, the powerful branch of the O’Neils in south Antrim and Down from Loch Neagh to the sea, owed military service to O Domhnaill is most extravagant. Equally so is the claim upon O Cathain, whose territory was the barony of Keenaght in County Derry. Cinel Moain, the O Gormleys and their kin, originally occupied the barony of Raphoe in Donegal, but were driven out of the Foyle between Derry and Strabane; a charter of the Cinel Moain, Inishowen and Fir Monach was given by O Neill to O Domhnaill in 1514. In the “Annals of Ulster” 1505 at the obit of Aodh Ruadh son of Niall Garbh, the son of Toirrdelbach an Fhiona the following statement is made: “It was he that preserved lordship from the mountain down into Connacht for Cenel Conaill and the rent of Inis Eoghan and the service of Cenel Modhain from the O Neills.” O Floind (O’Lynn) was chieftain of Ui Tuirtre, originally situated near the mouth of the Bann but afterwards in Dal Riada and N.E. A! ntrim—certainly not O Domhnaill country. Mac Gilla Muire (Gilmore, Kilmer, Kilmurray etc.) was a dependent of O Neill of Clannaboy. Ui Echach was probably that branch of the Oirghialla situated in what, roughly, is the present barony of Armagh; Oirtheara was the baronies of Oneilland E. and W. and Orior; Oirghialla was the MacMahon country around Monaghan—all outside O Domhnaillls orbit. Fir Monach is the present County Fermanagh, of which O Duibhdara, and later Maguire, was the ruling family, with Enniskillen as their chief seat. Mac Cathmaoil, variously anglicized Caghwell, Campbell, Cantwell, McCall etc., was chieftain of the Cinel Fhearadhaigh which is now the barony of Clogher, County Tyrnone. The MagCana (McCanns) were seated in County Armagh, and Muintir Birn were in the southern part of the barony of Dungannon, County Tyrone, while O Caragain occupied a district represented roughly by the parish of Killyman, County Tyrone. * This manuscript cannot be older than 1532 when Manus O Domhnaill wrote the “Life.” ** In “Prelegemene to the Study of the Later Irish Bards,” British Academy, p. 48. *** Ard Carne, 4 miles east of Boyle, Co. Roscommon was one of the five Connacht sees created at the synod of Rath Breasail A.D. 1111. In medieval times there were houses of Augustinians, Franciscans, and Benedictines there.
