dude...its hard enough finding an Active Clan...you are making it improbable by asking for an irish clan 
but then u never know....
If you dont find one..you can consider our clan (Booo) which is primarily UK based with a few of us from other parts of the world such as US and India... requirements are - Fairly regular on KZ3, Speak English, Have a Mic.
Message our clan leader: sah_destroyer
Best of luck.
