Her Majesty(1922)

Identical orphaned twins Rosalie (Mollie King) and Susan (Mollie King), are adopted by two aunts and live in separate households. Susan develops as a poor, wholesome farm girl, and Rosalie becomes a wealthy snob. Susan's beau, Ted Harper (Creighton Hale), confuses the girls' identities, but Susan wins his love after preventing Rosalie from eloping with scoundrel "Slick" Harry Ives (Jerome Lawler).
