Waves and colors of Western Europe

Since doing some reading about migration to Japan, re: Jomon and Yayoi periods, I can't help but see Japanese faces and wonder, 'Hmm, definitely Jomon.' Or, 'Oh, definitely Yayoi.'

But I've so wondered about some reading I've done about Spain and the rest of Western Europe. How Spain had invaders from the south (Moors) and the North (red-haired Vikings, or Norsemen). It's pretty fascinating to me, maybe more so because my brother (he's my half-brother but I never considered him anything but my "full" brother) is part Irish. He has brown, wavy hair and somewhat fair complexion. He could pass for Irish, or any of the more southern European extractions like Greek, Italian, Portuguese, Spanish ... he's sorta lucky that way!

But what compells me in terms of migration is that I'd like to learn more about where certain facets of the region originated. Red hair. "Black Irish." And, of course, the whole Protestant-versus-Catholic thing. I've seen my share of PBS documentaries about the history of Ireland and the church wars. Sad stuff. But was any of it aligned with ethnicities? Or were there brothers and cousins warring along those religious lines?

I find bloody, violent rivalries within small regions so compelling. To the rest of the world, say to someone like me in Hawaii, all Irish are pretty much the same at a glance. Probably much the same for someone from Ireland who takes a look at people in Hawaii. How could people in such a beautiful place not be able to get along? But it's true. There are problems everywhere.

So I'll post what I find tonight, and maybe the info will entertain, amuse and educate all the same.
