On October 10, 1888?, Margaret E. Nelson as widow of George C. Nelson applied for a pension based on his Civil War service. The application was filed from Missouri. The film is blurred so it's hard to read the date for sure. On Apr 21, 1891? there was a second application involving a minor named J.A. Stone. That name has (gdn) written after it. That could mean the application was made by the guardian of J.A. Stone.
You might want to consider ordering his pension papers from the National Archives. They've recently raised their prices but the pension packets, especially when a widow is involved, can contain a wealth of genealogical information.
