"The Grand Army of the Republic was a fraternal organization founded after the Civil War to provide all veterans of the Union Armed Forces with a forum for social and political activities and as a venue for debate and reminiscence of their service in the Civil War." (Grand Army of the Republic Museum and Library)

"The Sons of Union Veterans of the Civil War was a creation of the Grand Army of the Republic (GAR) which was formed in 1866. Wanting to pass on its heritage, the GAR in Philadelphia, Pennsylvania created a Corps of Cadets in 1878 which later became the Sons of Veterans of the United States of America (SV)... In 1904, the SV elected to become a patriotic education society and in 1925 changed its name to Sons of Union Veterans of the Civil War (SUVCW)... Prior to disbanding and before the death of its last member, the GAR officially designated the SUVCW as its successor and heir to its remaining property. On August 20, 1954, the SUVCW was officially incorporated by an Act of Congress by the passing of Public Law 605 of the second session of the 83rd Congress."
