Assuming what records contain without knowing can cause us to overlook materials that might help us with our research.
FamilySearch has had “United States, Burial Registers for Military Posts, Camps, and Stations,1768-1921” online for some time.
From the description:
Index and images of burial registers for military posts, camps, and stations, 1768-1921. This collection corresponds with NARA publication M2014, one roll consisting of two volumes of burials, most occurring between 1860 and 1890. The records are from Record Group 92, Records of the Quartermaster General, and are arranged by place of burial then date of death. See the descriptive pamphlet for a list of the posts, camps and stations.
One might be tempted to conclude that only soldiers are listed among the burials. That’s not a valid conclusion. A scan of the registers indicated that spouses and children are among the burials as well as the occasional support staff member. Many of the soldiers appear to have been career soldiers and outside the Civil War time frame.
The descriptive pamphlet can be viewed online at FamilySearch.
