Years ago I read Columbus's diaries, I don't remember much, but I seem to remember him speaking of number of inhabitants where they first landed. An island that is .2 square miles is very small and I question that it could sustain more than a handful of people. It would seem that the natives would have migrated to the larger Bahamanian islands. An island this small would not even have been able to accomodate Columbus's crew for one night.
It is small, but they were maritime people, so a small island could have accommodated more than a handful on a permanent basis. The ships themselves would have drawn a crowd from other islands. :')
