Around 1897, in Mankato, Minnesota, Maud Hart Lovelace met two girls --- Bick Kenney and Midge Gerlach. The three soon formed a trio that would be inseparable in their youth and remain friendly throughout their adult lives. Many years later, Maud told her daughter, Merian, bedtime stories about her girlhood adventures with Bick and Midge. Soon, she developed these tales into a popular series of books that was first published in the 1940s. Mankato was transformed into Deep Valley, Minnesota, around the turn of the 20th century. Maud became friendly storyteller Betsy Ray, Bick became shy, redheaded Tacy Kelly, and Midge became the practical, yet fun-loving, Tib Muller.
