where was Ga Inf, 19 Batt'n Co B. formed?

My cousin has asked me to help find info about her husband's ancestor, Dennis Baker Baines. Mr Baines is believed to have been home from the War briefly in 1864, Paulding Co., Ga. for the birth of his son. He left shortly after the birth and was never heard from again.
The closest name match from the CWS&S website is B.D. Barnes from Georgia Infantry (19 Batt'n.-State Guards) Co B. Does anyone know if Co B. was formed in or near Paulding Co?
