The American Film Institute Catalog of Feature Films 1921-1930, published in 1971, has actress
Alice Calhoun playing "Natalie Kingston" but the correct name, identified on screen, is "Natalie Knowles".
Natalie Kingston was, of course, a well known leading actress at the time the film was made, and so her name would unlikely to be selected as a character name for another equally well known player. After nearly 50 years, the AFI has not chosen to correct this mistake on their online catalog.
