I have a relative Robert S. Hannon Co.F,6th. Texas Volunteer Infantry--captured Arkansas Post Jan 11 1863 and died a POW at Camp butler Ill Feb 17-18th 1863..do you have any information, photos, etc on this person or know how I can find out more about Robert S. Hannon..I intend to go to Camp Butler soon but was thinking the graves of Confederate POW's would be unmarked..Any information will be helpful..

Many Thanks......James Hannon
