I ran into a fascinating article about Sen. John McCain —
The Wall Street Journal has an interesting article and accompanying video about the McCain families in Carroll County, Mississippi: the descendants of John McCain’s ancestors who still remain in the area where those ancestors owned a cotton plantation (Teoc), and the descendants of the slaves who worked that plantation and took their owners’ surname. The McCains have a biannual reunion where family members of both groups of descendants meet.
Charles McCain, grandson of a slave at Teoc, the white McCain plantation, was active in the Civil Rights Movement:
Charles McCain was a central figure in the local chapter of the National Association for the Advancement of Colored People. When civil-rights workers swarmed Mississippi in 1964, the black McCains housed white activists and received bomb threats and harassing calls.
