Miss Mischief Maker (1918)

Little Sallie O'Brien, who sells newspapers on the city streets, is adopted by Bridget Cassidy, the landlady, when her mother dies. Mrs. Cassidy treats the child cruelly, but soon the wealthy James Wilson befriends Sallie and takes her into his home. Sallie is befriended by Wilson's son Richard, but his daughter Marjorie dislikes the impish little girl. Although Frederick Mason is in love with Marjorie, she refuses to marry him because she finds him too lacking in boldness and chivalry to suit her romantic temperament. Having overheard Frederick's proposal, Sallie induces Bridget's son Patrick to visit the house in the guise of "the Duke of Galway." Marjorie becomes infatuated with the "duke" and promises to marry him, but Mrs. Cassidy appears and exposes her prodigal son. Richard saves Sallie from a whipping, while Marjorie finally accepts Frederick.
