Is Kamala Harris 1/3rd white (Irish), 1/3rd brown (Indian) and 1/3rd black (Negro)?
I can't find any definite information about this on the internet. Whilst her mother appears to be a full-blooded Indian, her father, Professor Donald Harris, who emigrated from Jamaica to the US, doesn't appear to be black.
The British colonized Jamaica in the 17th century. Sugar cane became the main crop, which was very labor-intensive to grow and harvest, so the British imported lots of African slaves. However, Donald Harris has written that he is descended from Hamilton Brown who was a slave owner and from Northern Ireland.
Attached is a photo of Donald.
