Rogan surname: questions
What does the surname Rogan mean?
Woulfe derives Rogan from Ó Ruadhagáin, 'descendant of Ruadhagán' (a diminutive of ruadh, red). A second entry, Ó Ruadhacháin, which he calls 'a variant of Ó Ruadhagáin', also carries the form, but only in brackets.[1][2]
Where in Ireland does the Rogan name come from?
Woulfe: the Ó Ruadhagáin were an Oriel family, chiefs of Ui Eathach (Tuath Eathach), 'a district embracing the present barony of Armagh', and 'common in Ulster and Connacht'; Matheson's 1890 figures show Rogan principally found in Antrim, Down and Leitrim.[2][3]
Are Rogan and Rowan the same name?
Woulfe lists Rowan among the forms of Ó Ruadhacháin, which he calls 'a variant of Ó Ruadhagáin' and under which he prints '(Rogan)' in brackets. He also warns that Ó Ruadhacháin's anglicised forms 'cannot always be distinguished' from those of a third name, Ó Robhacháin. The Four Masters' 'O'Rowan' of Leyny is glossed by O'Donovan as O'Ruadhain, which no source opened connects to Ó Ruadhagáin.[1]
Is O'Rogan a form of Rogan?
Yes. Woulfe's Ó Ruadhagáin entry prints 'O Rogane', and the Annals of the Four Masters record an 'O'Rogan, Lord of Iveagh,' who died in 1179.[2][6]
