In the 1600s many Huguenots (French Protestants) landed on Irish shores fleeing from France..
In 1710 when Queen Anne sent those 3,000 Palatine Germans to Albany, NY to chop down pine trees and make pitch and tar to seal her wooden war ships, she also sent about 3,000 more to Ireland...
Some of them stayed and some of them moved on to Canada a couple of generations later...after 1760 when the English took over from the French...
Plus the Scots who traveled back and forth to Ireland every few generations or so...My early to mid 1800s Irish were named Campbell, Irvine, Hunter :)
Lots of bloodlines to choose from...
If youre Irish you could be have French, German, Scot, English ancestors as well as a Black Irish/Spaniard...
Oh and the Vikings...
Bloody Vikings!
