It was a morning of solemnity and celebration at the annual Memorial Day parade on Monday, which featured the awarding of a posthumous Purple Heart medal to a World War I veteran. The morning began with prayers and a speech by Air Force Gen. David Nahom. The Purple Heart was awarded to the New Milford family of Clarence Henry Stone, who died fighting in France a century ago. After the national anthem and a bagpipes rendition of “Amazing Grace,” the parade kicked off in front of New Milford Library. Families lined Main Street as the parade proceeded to the War Memorial.
