It is quite surprising how they were just totally oblivious to the Black ancestry though. That was never the case for my family, not even my father's family and his parents looked predominantly European. I had to question him a couple times about his SSA admixed look but he finally admitted his grandmother was a Black woman. I feel like my father was like a Sandra Laing in a way, growing up as an admixed SSA looking person in a family who was seen as white. He was always called "el negro" /"the black" by his siblings and mother.
