The story of Molly Brown, who not only remarkably survived a flood as a baby, but also managed to survive the sinking of the Titanic.

Btw, another passenger who survived that fateful 1912 voyage, stewardess Violet Constance Jessop (2 October 1887 – 5 May 1971), also survived the sinking of Titanic's sister ship Britannia. Depending on one's point of view, I guess one could say she had either really bad luck or really good luck.
