Ó Dubhthaigh

Rev Patrick Woulfe
1923

Ó DUBHTHAIGH—IO Duffie, O Duhie, O Duhig, O Dowhie, O Dowey, O'Duffy, Duffy, Duhy, Duhig, Dowey, Douey, Dooey, Doey, &c, and sometimes, by translation, Black; 'descendant of Dubhthach' (black). This surname is found in all parts of Ireland, and, doubtless, there are several distinct families so called. The O'Duffys of Connacht are remarkable for the number of eminent prelates they formerly gave to the church in that province. The O'Duffys were also a family of note in Monaghan. In Munster, the name is generally anglicised Duhig, owing to the pronunciation of the final g. The family is, according to Keating, of Dalcassian origin. In Ulster, where the name is very common, especially in Monaghan and Donegal, it is sometimes anglicised Dowey and Dooey. See Ó Dúithche.
