The first black President? Are you absolutely sure?
From 1869 to 1889, the Presidents were called Ulysses S. Grant, Rutherford B. Hayes, James A. Garfield, Chester A. Arthur and Grover Cleveland.
I'm sorry, but that just screams "Motown boyband".
The list from 1845 to 1857 runs James K. Polk, Zachary Taylor, Millard Fillmore, Franklin Pierce.
Every one of those dated at least one of The Supremes.
And then there was Berry Gordy's Number One solo star, Calvin Coolidge.
If that wasn't the name of a brother from another mother, then I don't know what the hell was going on.
