How do they know the people were fair skinned and tall? I wonder if they were blue-eyed, too? Could they be kin to the "white tribe" of the Amazon?
Like you, I was wondering where they could have come from - especially using a cross like that.
I hope you find more information on this. It is intriguing!
Years ago I read an article about tall, blonde, blue-eyed people living in the high mountains of Colombia. The article called them, 'The-White-Cloud-People,' we had an engineer from Colombia working in our group (Zulma), I asked her and she said, yes they're there. I've never been able to find another word about them...and, I even wrote some letters.
