I am researching my gggrandfather, CAREY E. FULLER, from Greene County, Indiana. He told his son that he was a prisoner at Andersonville and told of a story that prisoners were dying of thirst when a spring began to bubble up where they were being held. This was looked upon as a miracle from God. I'm new to this list. Can anyone verify this information and tell me how to find out what Regiment Carey E. Fuller was in. Is there a list of the prisoners somewhere? Thanks for any help. pam
