My maternal grandmother (b. 1911/d. 1940) was of mixed race (white father and black mother, her father left and she was raised by her mom) Her husband (my maternal grandfather) was born in the 1890's in Northern Central Mexico , which consists of European/ Mestizo Mexicans.
My brother (we have several other siblings and we all share the same parents) did a DNA test and it reads: 27% Great Britain, 15% Cameroon/Congo, 14% Iberian Peninsula, plus a small percentage from 14 other regions. The estimate is: 43% Africa, 11% Mali , 6% Native American, 3% Asia , 46% Europe.
My dad was Black. My mom always referred to herself as colored because her own mixed race mother did. I grew up being questioned as to my race and bullied and teased by certain kids, which made me ask my mom about her family, all she would say was "tell them you're part colored and part Mexican." was as far as she went , another one of her responses was "you're father is colored and you always go by your father's race." Mexican is a nationality and not a race (unless you were born in the actual country) Me and my siblings were raised in a Black household and always identified ourselves as Black, but as I got older and learned a lot more about my mom's lineage I know better and identify with all 3 races.
Most of my life (and to this day) my race has been an issue with certain people putting me on trial with questions ( although they are kind) but that has really gotten old.
