Melissa Sue Anderson as Mary Ingalls
Before playing the eldest daughter of the Ingalls, Melissa Sue Anderson has already done roles on big name shows just like Bewitched and The Brady Bunch. And the professional level of acting definitely shone through as she gracefully handled the blind Mary Ingalls. She left the show after the seventh season and acted in several TV shows like The Equalizer, Alfred Hitchcock Presents, and Murder, She Wrote. And just like Melissa Gilbert, she also wrote a book about her time as Mary titled The Way I See It: A Look Back at my Life in a Little House.
She moved to Montreal, Canada, with her husband and two daughters in 2002. Then, she stepped off the limelight to focus on her family. Melissa didn’t also want her kids to feel pressured that they also need to pursue an acting career just like her.
