Hmm. Tough one.
The Irish have some great saints. I like St. Columba for his defense of satirists. St. Brendan may have made it to America before Leif Eriksson did (or so the story goes).
St. Denis has a good story. When the barbarians cut off his head, he picked it up and walked home with it. On top of that, he’s the patron saint of Paris. Way cool.
Some of the ones I like best have not been officially canonized: Erasmus, Dorothy Day, and Pope John XXIII.
