Lindy
From MIwiki
Lindy was the cabin boy of Captain Marley who along with his two other crewmen Rapp Scallion and Rum Rogers, sailed off to discover the treasure of Big Whoop. After the crew went their separate ways Marley split the map between his crewmembers with Lindy also recieving a piece.
After LeChuck was revived as a ghost he hunted down and killed all of Marley's crewmen except for Lindy, whose downfall was by far the most elaborate. Instead of killing Lindy directly he apparently lead him to becoming a victim of a pyramid scheme which would eventually lead him to bankruptcy. According to LeChuck Lindy spent his last years working in a circus and was killed when he was shot out of canon without a helmet (an obvious reference to The Secret of Monkey Island).
Because Lindy was not personally killed by LeChuck and none of his relatives (had he had any) appear in the games it can be assumed that his piece of the Big Whoop map is the one on display at the Antique Shop on Booty Island.
