What are the names of the two men who Huck Finn saves on the canoe?

In chapter 19, Huck saves two men’s lives by letting them into his canoe, what are the names of those two men in The adventures of Huckleberry Finn?

Thanks!

Huck and Jim then wait on the men and call them “Duke” and “Your Majesty,” respectively. Huck quickly realizes that the two men are liars, but to prevent “quarrels,” he does not let on that he knows.
