Earl Hamner's rural childhood growing up in the unincorporated community of Schuyler, Virginia, provided the basis for the setting and many of the storylines of The Waltons. His family and the community provided many life experiences which aided in the characters, values, area, and human-interest stories of his books, movies, and television series. Hamner provided the voice-over of the older John-Boy, usually heard at the beginning and end of each episode.
