Ms. Hall,
It may be better for you to post this query on the Illinois Message Board (link below).

Also, as far as Andersonville Prison Records and data contained there in, you may want to post your questions on the Civil War Prison Message Board (link below).

They both have people that monitor the boards that have resources that may be able to assist you more efficiently.
Respectfully,
