Deane surname: questions
What does the surname Deane mean?
Woulfe gives Mac an Deagáin as 'son of the dean' (Irish 'deagán', 'deagánach', Latin 'decanus') and Ó Déaghain as 'descendant of the dean' (Irish 'déadhan' or 'déaghan').[1][2]
Is Deane an Irish surname?
Woulfe prints Deane under two Irish names. He says Mac an Deagáin 'is now very often translated Deane', and that Ó Déaghain, which includes Deane in its forms, is a scattered surname. These entries describe Irish families only; the sources do not say that every Deane descends from them.[1][2]
Where in Ireland is the name Deane found?
Woulfe says Mac an Deagáin was found in the 16th century in many parts of Ireland, especially Donegal, and Ó Déaghain at the end of the 16th century in the south of Ireland and in Donegal. Matheson's 1890 report lists Mayo, Cork and Donegal as the principal counties for Deane.[1][2][3]
