In visiting the Camp Nelson cemetery, I found that the burials had been gathered from the extensive random burials in the surrounding woods, which had been used as a camp and training ground for Confederate troops. Many died from diseases which swept through the camps. Most were from graves marked only by a pile of stones or a marked board. Most burials are marked "unknown". But this Lonoke area is not particularly close to Little Rock, and I can't imagine anyone dying there being described as dying in Little Rock. A church near the cemetery was used as a hospital during the war. Images from the cemetery, including the historical marker relating the above info should be available online.
