I am looking for primary sources (e.g., letters, diaries, reminiscences, period newspaper articles from or about them) for the following companies in the 11th Georgia for a study I am doing on G. T. Anderson's Georgia Brigade (aka: Bartow's/Sam Jones'/D. R. Jones' Brigade). What I need is information on the formation of the companies, e.g., recruiting, organizing, details on their move to their rendezvous point in Atlanta, and details on their move to Richmond.

Company A - Gainesville Light Infantry (Hall County)
Company B - Lee Volunteers (Lee County)
Company C - Murray's Rifle Company (Murray County)
Company D - Gilmer Boys (Gilmer County)
Company E – Fannin Young Riflemen (Fannin County)
Company F – Mrs. Joe Brown’s Boys (Gilmer County)
Company G – Beauregard Rifles (Catoosa County)

This regiment was originally called the 10th Georgia. I would also like to know specifically when (what date, and why) did its number change and it become the 11th?

For any assistance you can provide, thank you.

Any help will be greatly appreciated.
