Looks like we have close to the same situation. I have curly not nappy hair. I have the skin of a mexican but I am also 100% black.
I do have a big nose though. I ask my self this question every day... btw im From haiti and both of my parents were born and raised there.
Most of the time you would have white ancestry especially if you are from the Americas. In Africa it will depend. My dad had curly hair thats about it with me and I am 100% sure I have no white ancestry.
Its common in North-East & Sahara populations.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
