Have just found an Administrators Notice for Henry A Moore of Yallabusha County dated 6 Oct 1862 from Administrator L W Moore stating that Henry A Moore was deceased prior to September 1862.

I guess that the correct date of death should be 14 Aug 1862, but still would like to see any other information that might be out there to confirm one way or the other.
