Everyone's got a bit of Irish in them somewhere. I do myself from my mother's side, even though my family used to be Welsh nobility waaay back.

I think we'd have to have adjudication on the best claim to being a Celt.

Alternatively, we could exploit a little loophole - according to the Celtic Nations webpage, it includes Scotland, Ireland, Wales, Brittany, the Isle of Man and Cornwall... but apparently Galicia in Spain is petitioning to join as well. So we could take on a Spanish pilot considering there's no Team Mediterrania as of yet.
