Some people may inherit traits from an ancestor many generations ago, the genes can be carried, some Eastern Europeans say they have slightly Oriental features and I have been told this. I would say that the Vikings may have bought back slaves from there and some people from Mongolia did get as far west as Poland and Germany so I read. DNA testing would help. If an Asian was born with blue eyes and they still had all other Asian features, then it could indicate European blood many generations back. You'd be surprised how many of us may have ancestors from a place far away from where we think they came from. Never underestimate how people travelled.
Sorry, I just don't believe any of that!
For years I have been accused of being Irish, Italian or Spanish. Even as late as yesterday when some oick called "Amigo" to me from a car window! 
My (documented) family tree goes back as far as 1550's on both maternal and paternal lines.
Guess what? English all the way!
No Welsh, Scottish, Irish, or any other nationality!
My mother was born in Wales - of English parents.
I have a 3G Grandfather born in Jersey - his parents from Devon, and in Jersey for just 5 years.
So judging by looks (or judging a book by it's cover) will tell you absolutely nothing! IMHO. 
I have posted before of my views on DNA testing.
That upset a few people 
But I remain a skeptic 
What I am talking about though is way way back like many, many centuries, well before the 1500s. You wont be able to know without DNA but I know some Eastern Europeans with no known ancestors when have been tested and their ancient DNA says 7% East Asian. And I have just stating what I have heard from people who have had their DNA tested and read from studies. I am also a skeptic as well you know.
