1883
On Nevember 5, 1883 a Sixth Ward (beige) was carved out of the Fourth and Fifth Wards. Its boundaries started at Butler and the GRR (today's Grady Hospital) north to North Ave at Myrtle St, then up Myrtle to the city limit at 3rd St. Follow the arc of the city limit to Williams, south to Cain (International) then James (Church) to Forsyth south to the tracks then east on the tracks to origin. This separated the wealthy Peachtree corridor from the other parts of north Atlanta. (Garrett Vol II, p. 53–54)
