Ulysses S. Grant was fightin to end slavery…Do tell?

U.S. Grant was the last American president to have owned slaves. Grant freed his personal slave in 1859…

…However, the slaves his wife inherited from her father were not freed until after the war. When Richmond fell to the Union army, only one person was allowed to be escorted through the streets of Richmond by a servant. That person was Julia Dent Grant and she openly flaunted that fact.

Do you suppose those are Grant's kin folk in the background?
