I don't think the KMC would have any pre-European natives. It's simply too far south and too far from any major landmasses (aside from Antarctica, which is not populated).
 
Ok, what about Magellanica, that is in the South Atlantic, any pre-european natives down there?
I think both KMC and Magellanica would be very difficult to to reach due to this:
https://en.wikipedia.org/wiki/Antarctic_Circumpolar_Current
i think part of the circumpolar current would go through the magellanica-antarctic strait (when not frozen up) but most would pass around the north .
this circumpolar current would make early colonisation extremely difficult
 
So we can officially and finally decide that KMC and Magellanica were empty virgin lands when discovered and settled by Europeans?
pretty much so yes.
Although during the last iceage there probably was a landbridge connecting it to south-america (since it connect to the same continental shelf that the falklands sit on)
So Magellanica could harbour species that went extinct in south-america. But i don't expect it to be reached by hominids over that landbridge.

Magellanica probably will have a ridge of mountains through its center (west-east) and a ridge going north considering it is located on several rifts of the continental plates, a situation not unlike that of iceland
