The queen is German, dude! She has nothing to do with Druids!
Of course, how could they not? :) Druids were all over the place in Ireland, England, Gaul, Europe in general. We came to the Americas too. Think about it... There were Druids in Ireland and Scotland seen walking around up to 1700, and the Americas were discovered in 1492. We escaped the the Americas at least by that time, unless you count Brendan's voyage from Ireland around 800. In that case 1200 years ago.
