Ó hEodhasa
Ó hEODHASA, Ó hEODHUSA—I—O Hoasy, O Hosey, O Hossy, Hosey, Hussey, (Oswell, Oswald); 'descendant of Eodhas'; also written Ó hEoghasa, which see; the name of a family of Cinel Eoghain, in Ulster, who were chiefs of Cinel Tighearnaigh, but afterwards migrated to Fermanagh, where they became bards to the Maguires. The family produced several distinguished literary men, among them Eochaidh O hEodhasa and Bonaventure O hEodhasa who flourished at the beginning of the 17th century. The name is now very rare in Ulster, having, according to O'Donovan, been changed to Oswell, which apparently has been more recently further changed to Oswald. Before the end of the 16th century, it had spread to Leinster and Munster, but its anglicised forms in these provinces cannot now be distinguished from the Anglo-Irish surname, Hussey.
