Thomas:
I've checked my indices and don't find them.
You might want to post your query on the Illinois in the Civil War Message Board.
To do this, click on "return to index" at the top of this page.
Then, at the MS in the CW MB homepage, go to the top left and click on the appropriate links that will lead you to the Illinois board.
I wish you luck! Hope you find a granddad's photo out there somewhere! -- Jim Huffman, Gainesville Vols
