It's easy for people to think that he was Atmoran but also for him not being from Atmora, but perhaps Atmoran

Roscrea is an island in the sea of ghosts - between Atmora and Skyrim, Uriel V led an expedition there and conquered it, people there spoke ancient nordic and were 7 feet tall - atmorans are described as much taller than Nords. It also didn't froze like Atmora did. So if Talos was born there, and then came to Skyrim, people could easily think he was from Atmora, as he came from the north, was taller and spoke the ancient language. I also believe that Roscrea wasn't discovered before Uriel's conquest.
