I would guess that the line "ó Chluain go Stuaic na gcolum" refers to two local placenames near Rossmore in Tipperary which was part of the Ó Duibhir territory. The cross(roads) of Clune and the pub Coffeys of Stuke are still well known local landmarks. Colum nowadays spelt colm presumably meant dove , all part of the wildlife theme which runs through the song.
