American Gold Star Mothers
American Gold Star Mothers, Inc. (AGSM), is a private nonprofit organization. It is a group of American mothers who lost sons or daughters in service of the United States Armed Forces. It was formed in 1928 for mothers of those lost in World War I. The organization has a congressional charter under Title 36 § 211 of the United States Code. The name came from the custom of families of servicemen hanging a banner called a service flag in the windows of their homes.  The flag had a star for each family member in the Armed Forces.  Living members of the military  were represented by a blue star. Those who died in combat were represented by a gold star.
