Violet Jessop was a stewardess who survived both the Titanic, and on it's sister ships, the Britannic and the Olympic. and on all 3 voyages, something went wrong.
- The Olympic, when it was struck by a torpedo. the ship survived and actually retaliated, striking head on into the German U-boat that fired on it.
- The Titanic when it sank from the Iceberg
- and finally , the Britannic when it sunk from an underwater mine, during WW1. She was serving as an on deck nurse.
The Olympic was the only surviving member of it's liners, before being dismantled in the late 1940s.
EDIT: correction, the Olympic actually collided with the British warship HMS Hawke, when Jessop was on board. the U-boat incident happened after her service on the ship.
