The most famous Irish youtuber at the minute is Jacksepticeye (Sean Mcloughlin). He is close friends with a few other famous Irish youtubers; CallMeKevin (Kevin O'Reilly), RTGame (Dan Condron), Daithi De Nogla (David Nagle) and Terroriser (Brian Hanby). They form the group the 'Irish Lads'. The most popular (and probably only) irish gaming group right now. They're not an official group but they have made quite a few collaborations and are probably going to make more. I'm just a fan writing this but I watch all of these youtubers and this is all I know :).
