Rogan, as an Irish surname, is derived from the Gaelic Ó Ruadhagáin 'descendant of Ruadhagán' (a diminutive of ruadh, meaning 'red'[1]).[2] The surname Rogan also occurs in other languages, for instance in South Slavic contexts, where it is derived from rog, 'horn'[3][4] - among Serbo-Croatian speakers it is more common among Croatians than among Serbs,[5] and it also exists among Slovenians.[4]
