Memorial Day, originally Decoration Day, was first widely observed at Arlington National Cemetery in 1868. Major General John A. Logan, head of the Grand Army of the Republic - a Union veterans organization, established Decoration Day as a time to decorate the graves of soldiers who died during the Civil War.
In the families that I research, there are many who served in America's Wars, but only a four, that I know of, died during a war. Those four men died serving in the Confederate Army. One, James S. Pitman, was the husband of Georgia Ann Frances Bryan and the other three were brothers; John Tolbert Regan, James Monroe Regan, and Thomas Span Regan.
