Atlanta, Georgia but really Chattanooga, Tennessee
In 2015 a Jason Longshore wrote an article called "A detailed timeline of the origins of Atlanta soccer". The title speaks for itself, the year cited is 1912 and the whole article is available by clicking immediately below:

But Jason in it made one, identifiable mistake. It is that A.S. McLundie what not the Atlanta organiser, who remains unknown, but Chattanooga's. But he wasn't native. Archibald Stephenson McLundie was a Scot, born in 1885 and in Glasgow, so aged twenty-seven in 1912. His parents were also Glasgow-born, his father a brass finisher to trade. Archie himself was by 1901 an Architect's Apprentice. But in 1906 he decided to emigrate and presumably directly to Tennessee. And in 1912 he recorded there as a mechanical engineer and draughtsman, one clearly with an interest in and a reputation for Association football.
He seems also to have married in Chattanooga, in about 1914, his wife local girl Elizabeth Griffiths, was naturalised in 1916 and by 1920 they had had two children, he was working as a Patent Attorney but is also a War Veteran living in Washington D.C., and one seemingly with health problems, quite possibly a war-related stomach wound. That is because that by September that same year at just thirty-four he had passed away, his death from stomach-bleeding. It took place at the Hoffman General Hospital on Staten Island in New York he recorded as a US Army Officer. Indeed he was a Lieutenant, described as such on his headstone on his grave in the Chattanooga National Cemetery.
