which is called Inis Screabhainn; although Clann Néill" (a branch of the O'Dowds) "is considered to have conquered that territory, it is not through native right that they took it but by force following the killing of Dáibhidh Ó Caomháin and Domhnall Ó Caomháin, whereupon Clann Néill were in the chieftaincy for a period, and Niall [g]s. Niall was killed by Muircheartach Fionn Ó Caomháin in revenge for [the loss of] his land." At 276.11 Inis Screabhainn, noted as both the foregoing and Soighean Uise tar Abhainn, is called "The chief homestead of Ó Caomháin." 275.17 states "Ó Loingsigh and Ó Caomháin of An Cuirreach from Muine na bhFiadh (or Muine Dhiadh is its name today." High Medieval era Following the Anglo-Irish invasion and settlement of Connacht in the middle decades of the 12th-century, families such as the Clann Chaomháin lost their territories, been exiled or becoming tenants-at-will under the new lords. King Sén-Brian Ó Dubhda of Ui Fiachrach Muaidhe (died 1354) regained much of these territories but mostly allotted them to his own followers. Annalistic references Caomhán himself does not appear in the annals, and few of his descendants feature in the extant Irish annals. The Annals of the Four Masters contains a references under the year 1294, stating that Dermot O'Caomhain died. A more fulsome entry, sub anno, 1306, occurs in the same annal: A great depredation was committed by the Clann-Murtough O'Conor in the territory of Carbury. David O'Caomhain, Chief of that tract of country extending from Tuaim-da-Bhodar to Gleóir, a rich and affluent brughaidh farmer, Donough Mac Buidheachain, and many others, were slain on this predatory incursion.
