Lorelein.

Lorelei1843, from German, name of a rock in the River Rhine near Koblenz, Germany. In legend, a lovely woman sat atop it and sang while combing her long blond hair, distracting sailors so their ships foundered on the rock and they drowned. The second element of the name probably is Rhenish dialect lei "cliff, rock;" the first element is perhaps from Middle High German lüren "to lie in wait"
