On the vein of how we had a polynesian migration into Madagascar which kept their language, could we have some africans landing in a sparsely populated region on the Americas and keeping a language isolate there?
Or, otherwise, some (native) americans landing somewhere in Africa?
Also, which groups would be more probable to do this, assuming a, say, 1000 POD? Or a later one, if you want. I was thinking of those ships who sailed off Mali in 1311.
