Betty Duvall
Betty Duvall
was a Confederate spy during the American Civil War.
From Washington, D.C., she was the daughter of Eli Duvall Sr. and Sarah Duvall.
Washington D.C.-based spy Rose O'Neal Greenhow gave her a note about a Union plan for the first Battle of Manassas to give to General P. G. T. Beauregard; Duvall carried it tucked in her hair. She continued to be a spy, and for one of her missions she brought her cousin. She was descended from the immigrant Mareen Duvall.
