The Letters on your Button- NHDVS -stands for: National Home for Disabled Volunteer Soldiers. It was created in March 1865 to care for the sick and injured volunteer Civil War Soldiers and continued to care for them into the 1900s until they began to die from old age but then they also were authorized by Congress to care for the Volunteer soldiers during WWI. The NHDVS was finally absorbed with a couple other organizations into the Veterans Administration in 1930.. We find them often here in Virginia due to the large convalescent Civil War soldier population we had here.
