Concept

Friendly Wandering Lawman

Tropes

Deputy US Marshal in the SW Colorado area, regularly showing up in Babylon, always looking for this-or-that fugitive or gathering census data, etc.

Super-polite and complementary to the employees at Madame Darnell's Gentlemens' Establishment but never actually goes in, despite the girls' efforts/teasing; "perfect gentleman"
Always clean, somehow.
