What is the answer for the question: What is the alias of the person aunt Hortense fears is a fortune hunter? from the following article ?  At a St. Louis opera house in 1860, a singer in blackface named Jerry Barton, known as "King of the Minstrels", comes backstage and asks his sweetheart, Lettie Morgan, to elope. Lettie's Aunt Hortense, fearing that Barton is a fortune hunter, tells Lettie she is not the heiress she thought she was and that she has been living off her aunt's charity. With no fortune to hunt, Barton informs Lettie that an artist cannot be burdened with the responsibility of a wife. Outside the opera house, Lettie meets a chorus girl named Honey, who is preparing to leave with her theatrical troupe in a caravan heading West. When the troupe's producer mistakes Lettie for the star, she joins the group as "Mary Varden". The troupe's wagon train is escorted by Captain Tex Autry of the U.S. Cavalry and his singing plainsmen. The troupe misses the wagon train, however, and must travel alone. On their way to San Francisco, the caravan is ambushed by a gang of thieves. Tex and his men arrive on the scene and following a gunfight, the gang is chased off. After Tex saves Lettie from a runaway wagon, he comments on the foolishness of risking his men's lives for a bunch of "crazy showgirls". Angered by his insolence, Lettie decides to walk rather than ride with Tex. Eventually she gets tired and asks Tex if she can ride with him. The troupe arrives safely at Fort Henry, which is run by Colonel Seward.
The answer to this question is:
King of the Minstrels
