Historical trivia...
I went looking for a song to give Slim a hint about the birth name. The Google search led me to Stephen Adams, aka Michael Maybrick. Michael Maybrick wrote ballads and for a long time was paired with Frederick E. Weatherly, who is often credited with the lyrics to the song "Danny Boy." This is of interest to me because I have a firearm named Danny Boy, in large part because of that song. The thought pattern was: Anyone looking down the business end of this Dan Wesson had better start singing "Danny Boy," because, indeed, the pipes are going to be calling for him. Heh heh heh.
Anyway, it was a neat connection, for I did not know that they collaborated on the ballad I was seeking. The same ballad that would give Slim the birth name.
When were these ballads written? In the 1880s, right smack in our time period.
To me, that's pretty derned cool.
