Young Lord Stanley, possibly re-issued as His Only Son, is a 1910 American silent short drama produced by the Thanhouser Company. The film focuses on Jack Stanley who is disinherited by this father, Lord Stanley, for refusing to marry his cousin. Jack heads to America and takes a job as a groom. He is dismissed from his position after his employer learns of Jack's affections for his daughter, Ann. Meanwhile, Lord Stanley decides to reinstate Jack in his will and then promptly dies, giving him his entire fortune. Jack reads of his father's death in the newspaper and learns of his father's will. The film concludes with the lawyer bringing Jack to a dinner party as "Lord Stanley". Ann's father wishes for her to earn his affections, but she is defiant and does not even look at him. Once she learns it his Jack, they kiss. The scenario was written by Lloyd Lonergan and the only known actor is Justus D. Barnes as Ann's father. A surviving print of the film exists in the Library of Congress and it shows the improvement of the Thanhouser interior sets over films from months prior. The film was released on October 25, 1910, and was met with mixed reviews.
