The Grand Army of the Republic (GAR) was a fraternal organization of honorably discharged Union Civil War veterans. Some of their rituals were based on Freemasonry. The GAR was founded in 1866 by Benjamin Franklin Stephenson in Decatur, Illinois. By 1890 they had 409,000 members. The GAR was involved in charity and politics, and they lobbied for soldiers homes and pensions. They also began the tradition of Decoration Day on May 30th, now called Memorial Day. Five presidents were members of the GAR: Ulysses S. Grant, Rutherford B. Hayes, James Garfield, Benjamin Harrison and William McKinley. The last GAR member, Albert Woolson, died in 1956 at age 109 (although census research indicates he may have been 106 or 108). He was also the last undisputed surviving Civil War veteran on either side.

Here are three examples of standard upright marble VA military grave markers that you might find in national or private cemeteries. These measure approximately 42″ x 13″ x 3″. Some of the newer ones are made of granite. Many have an optional religious symbol at the top of the marker (like the cross in the example at right). For a list of these see the Veterans Affairs website:
