am curious if you know of any source that might have posted/available currently unidentified images of Confederate colonels/officers in Louisiana?

Am still trying to find an image of my gg-uncle Colonel John Griffith of the 11th/17th Consolidated Arkansas Infantry (see link below) in his uniform.

Am wondering if a Baton Rouge (or other LA) photographer might have taken his image when he was in the Port Hudson area, etc.

Any suggestions, help, etc. you might be able to give is VERY greatly appreciated!!!!

thanks,

Kenneth Byrd
