Task: Question Answering
Input (English): Passage: Due to an error in Heaven, Adam "Duke" Byron, is born without a soul in 1858. The "Book of Destiny" shows that he was supposed to marry a minister's daughter in 1885, two years prior to the present, and set a fine moral example. Instead, he is a saloon keeper and gambling hall owner in Glacier, Montana. As it was the fault of his department, Michael is sent to set Duke on the life path for which he was destined, but Michael must do so as a human being, without miracles, not even a small one.
Michael encounters Bill Plummer. Plummer and Duke are rival saloon keepers and partners in a mining company, but due to a dispute between them, the mine is closed, leaving many of the townspeople destitute. Plummer has hired the Kansas City Kid, a gunslinger, to kill Duke. When Bill finds out that Duke knows about his plan, he gives Michael a lift into town and as Plummer had hoped, Duke mistakes Michael for the Kid. Duke's henchman, Treason, takes a shot at Michael, narrowly missing a young girl. Furious, parson's daughter and schoolmarm Drusilla Wainwright goes into the "Copper Queen", Duke's saloon, and slaps him.
Drusilla and most of the other residents want to take the law into their own hands to take back their town, but Sheriff Matt Bodine talks them into waiting until Plummer and Duke's men kill each other first. 
Michael accidentally foils the Kid's attempt to shoot Duke. Duke is convinced he has switched sides, but when he learns that the now-dead would-be assassin is actually the Kansas City Kid, he believes that Michael is a smart, ambitious outlaw, so he hires him. Ginger, Duke's girlfriend and showgirl, takes a great liking to Michael, but Treason hates him on sight. 
Question: What is the nickname of the person who was supposed to marry a minister's daughter in 1885?
Output (English): Duke.
