In a fit of escapism I picked up a book at the grocery store by author Anna Lee Waldo entitled "Circle of Stars".  The preface of the book is that Druids from Wales escaping the onslaught of Christianity made their way west across the ocean. They later established a route from Wales to what is now Florida. This migration supposedly explains the presence of blond/blue-eyed American Indians which early explorers of North American found in along the southeastern coast.

 

I haven't had time to much more than crack it open.  However I am curious if anyone else has ever heard this speculation?
