Walnut Grove is the home of the Laura Ingalls Wilder Museum, dedicated to the author of the "Little House on the Prairie" books. Wilder and her family lived in the area for a part of her childhood and the location is the setting for the "Plum Creek" part of the "Little House" book series. Charles Ingalls, her father, was the community's first justice and her only brother, Charles Frederick 'Freddy' Ingalls (November 1, 1875 – August 27, 1876), was born in Walnut Grove. The name "Walnut Grove" was also used in the "Little House on the Prairie" television series; however, the program was filmed in California.
