A Misquito Indian from Central America was given the name Will by English sailors, with whom he shared a common enemy in the Spanish. He spent some time aboard a British vessel as it patrolled the Caribbean in 1680, but when the they stopped to forage for food on one of the Juan Fernandez Islands a year later, it seems they forgot about poor Will who had gone hunting in the jungle: His British shipmates pulled anchor after spotting some Spanish ships in the distance, leaving Will behind.
Will survived three years alone on the island, fashioning hooks with which to fish and hunting seals, until being rescued by another British ship. Some believe that Will was the inspiration for the character Friday in the book Robinson Crusoe--the name by which the island is known today.
