Task: Question Generation
Input (English): Passage: Warlock is a small Utah mining town of the early 1880s. Cowboys working for Abe McQuown often come into town to shoot the place up, kill on just a whim, beating or humiliating any sheriff who tries to stand up to them. The Citizens' Committee decides to hire Clay Blaisedell, a renowned gunfighter, as town marshal in spite of the misgivings of some, such as old Judge Holloway who insists that the situation should be handled within the law (though a loophole prevents it from being done effectively).
Blaisedell, famous for his golden-handled revolvers, arrives in Warlock with his devoted friend, Tom Morgan, his club-footed, right-hand man, who is no slouch with a gun himself. Morgan has a reputation as a heavy-drinking gambler, but Blaisedell insists that Morgan is part of the package. They even take over the local saloon and rename it the "French Palace" (something they appear to have done in previous towns, since they bring the signboard with them).
Their first encounter with McQuown's men is without bloodshed. The cowboys are intimidated by Blaisedell and one, Johnny Gannon, stays behind. Gannon has been put off by their propensity for killing, particularly the shooting of victims in the back, for some time now and resolves to be more law-abiding.
Morgan learns that his old flame, Lily Dollar, is coming to town on the stagecoach, and she is accompanied by Bob Nicholson, brother of Big Ben Nicholson, who was recently killed by Blaisedell. Lily had left Morgan for Big Ben and knows that Morgan pushed Ben into challenging Blaisedell, who killed him as a result. She wants Blaisedell dead to punish Morgan.
Morgan sets out to meet the stagecoach but it is robbed by some of McQuown's cowboys as he watches from a distance. He takes advantage of the situation to kill Bob Nicholson unseen. Lily arrives in town and sees Morgan there. She believes that he pulled the trigger, although this is based on intuition rather than evidence.
Output (English): What is the full name of the character who whose brother was killed by Clay Blaisedell?
