Famous quotes containing the words david and/or duncan:
“Down the road, on the right hand, on Brister’s Hill, lived Brister Freeman, “a handy Negro,” slave of Squire Cummings once.... Not long since I read his epitaph in the old Lincoln burying-ground, a little on one side, near the unmarked graves of some British grenadiers who fell in the retreat from Concord,—where he is styled “Sippio Brister,”MScipio Africanus he had some title to be called,—”a man of color,” as if he were discolored.”
—Henry David Thoreau (1817–1862)
“Have you checked the children yet?”
—Fred Walton, U.S. screenwriter. Curt Duncan (Tony Beckley)
