Friends share plan and timeline for Odell Rochambeau Museum

In a small envelope tucked in her purse, Hartsdale resident Susan Seal carries an 18th-century French musket ball, which she found in her garden on Rochambeau Drive.

“On my front lawn and on Sunningdale Golf Course, there were 5,000 French soldiers in 1781 making musket balls,” Seal told the Dispatch.

In 1998, she moved to the street, named after French military officer Jean-Baptiste Donatien de Vimeur, comte de Rochambeau, who aided the Continental Army during the American Revolution. She then became aware of the derelict Odell House nearby, which served as the headquarters for Rochambeau and his troops from July 6 to Aug. 18, 1781, while George Washington and the American troops were camped in Ardsley.
