John Edward Simpson’s family had appealed for a benefactor to buy the note, which was put up for auction earlier this month in Long Island, New York.

Simpson’s great-nephew John Martin said the note will soon return to Belfast, where the Titanic was built. “For it to be on its way back is just amazing and so appropriate now just ahead of the 100th anniversary of his death.
