Historic Photographs Of "White" Slaves - Historic photos of "white" slaves from Occupied Louisiana, 1863 and 1864: These children were minority African Mulattoes and most states considered them legally Black for having 1/8th or more African ancestry. As a side note, Sally Hemings was 1/4th African so she and her and Thomas Jefferson's children would have had similar appearance. Racial intermingling, both consensual and non, was much more common in the pre-war South than many tend to believe.
People who don't read history books are unaware that a huge number of "cowboys" driving herds to the railheads in Kansas were Indians. And many don't know that some of "Indians" who raided the drives for beef in the the "nations" were runaway slaves and ex-slaves adopted into the tribes in the Oklahoma territory. Western movies don't tell you that.
