That's John Miller's advice to Irish-Americans. Miller argues that St. Brendan should be the patron saint of Irish-America because it's possible that Brendan was the first immigrant to reach N. America. The fact that Brendan's feast day is March 16 makes it feasible to have a two day Irish festival, if anyone wants to take Miller seriously. {I misread that. Brendan's feast day is May 16, which means the festival will have to be seriously extended. Thanks mdb.
I remember coming across an odd text written by someone whose expertise was in languages of the Iroquois nation. He believed that Irish people had been as far inland as Lake Ontario because the names Oswego and Oneida made no sense in the local languages. He also attributed the tales of great white men and the development of lacrosse to Irish men, some of whom obviously brought their hurleys with them. I thought it was weird then and I haven't changed my mind, but who knows? At least it's kind of fun.
