need an Irish battle name

[Rawlinson]

I've just joined a local chapter of Dagorhir Battle Games. Pretty much, we beat each other up in large numbers with foam weapons. I'm supposed to have a "battle name," since apparently my normal one isn't good enough for them. I'm more Irish than anything (except American, you could argue), so I thought it'd be cool to have an Irish battle name.

Any suggestions (preferably with translations)? I'd like it to sound impressive (without it being too hard to pronounce) and have an interesting meaning.

Oh, and since we're making this an official club at the University of Pittsburgh, we'll have $1000 per semester to spend on weapons, garb, etc. for our little group of Pitt students to use (currently at 7, we need 10 for the funding), so I will likely be fighting kilted. I'm thinking black denim, knife pleated, resting at my true waist with a wide apron. Kilt discussion here.
