has been credited under his Irish name Cathal Ó Cochláin, which Discogs claims is his real name:

He has been credited as such. However, I'm not sure however what's on his passport and what we should consider his name and his alias. Any ideas? Some of his bandmates in Fatima Mansions also have both English and Irish names.

An answer here mentions that only the Irish name tends to be on the birth certificate, and also mentions Enya:

We already have Enya entered as Eithne Ní Bhraonáin even though her name's often rendered as Enya Brennan:

Went ahead and switched him over to Cathal Ó Cochláin, aliased where appropriate.
