Mr. Strawn, 1902

Most remote islands, in the Pacific or otherwise, have stories of a lone soul, stranded on an island, surviving on Coconut milk and shellfish.  Palmyra's first documented example of a "Robinson Crusoe" type, comes from an article describing various remote islands and their features (poorly named "Islands without owners", despite several of the locations, including Palmyra, being owned):

So also now is Palmyra Island, where for a considerable period a solitary English recluse, named Strawn, had his abode. Fish here are abundant, and in great variety, but turtle are described as "scarce." Curlew, snipe, and plover are, however, plentiful, and delicious land crabs abound, so that apparently Mr Strawn's successor, whoever he may be, will not have to go hungry. 

Whoever Strawn was, and however he ended up on the atoll, he set a precident for later residents like French sailor Roger Lextrait, and despite a lack of detail, adds to the mystique of Palmyra's history.
