I got to thinking about black being enslave and all that well since back then black was not allow with white so there fore a mix (white/black) baby couldn't be born when was the first Mix baby born?
You do realize the first time the races encountered each other was not when the Europeans in the US happened to stumble across Africa and bring back slaves... there were Africans in Europe a long time before that... so it is really hard to tell when the first "mixed" baby was born. As for it being illegal. Well so are a lot of things. Doest mean they dont happen.
There is no possible way of telling that.
