Lauryn was born on February 1st in 1957. Nothing is known about her early life or her parents, except that she could have been of British origin. One day she showed up at the hotel where Mr Ashmann offered her a job. She disappeared on April 30, 1972. Andrea Massino was the only one who reported her as a missing person. It's unknown what happened to her, but she was either killed as she was the wrong girl or she didn't survive Wyman's experiments.
A milk carton with her missing poster can be found in the game. Her profile is present in Rosemary's book.
