Hello - I just stumbled onto your message while looking for the location of the Gritter District, Cobb Co., Georgia. In case you have not had this question answered, there is a Gritters branch of the Marietta, GA public library. Perhaps it is named for the Gritter(s) district? I see on an online map that it is in the northern part of what is now Marietta. You may wish to telephone the Marietta Museum of History with your question: 770-794-5710. The museum focuses on the history of Marietta and Cobb Co. -- with no other relationship to Georgia than doing family research for someone else -- Jean E. DeLauche
