A Girl's Desire (1922)

Mrs. H. Jerome Browne, wife of a wealthy American, sends her daughter, Elizabeth, to a boarding school and goes to England to "find" a family tree, a title, and some heirlooms to go with them. Lady Dysart, widow of Lord Dysart, sells the heirlooms of the Dysart castle to obtain money to send her son, Cecil, to America so that he may marry well. Cecil and Elizabeth meet and are about to marry when Richard Jones, the real heir to the Dysart title masquerading as a journalist, intercepts the elopement and reveals Cecil, Lady Dysart's son from a former marriage, to be an impostor.
