Sir or Ma'am,

Chickamauga, TN? Do you mean Chickamauga, GA? If you are referring to the National Military Park, you need to contact the National Park. They have to validate/approve of living historians that assist at the Park and may be able to help you with a group that is already authorized.

You may want to contact Lee White at LWhite64@aol.com

Respectfully,

Gerald D. Hodge, Jr.
War Between the States Historian
