Hello, Martha.
This discussion forum is for the sharing and discussion of information. Anytime I can I am willing to share what I know for the benefit of all.
It sounds like you are asking for a book on little-known old west gamblers? Most books I know of contain information on the more well-known gambler's, however, many books, including mine, will included associates of those better known gambler's. Sometimes, digging around into the lives of those associates uncovers the history of a very interesting gambler who for what-ever reason missed out on becoming famous, but should be. Again, I will push my book your way as I do have a "rogues history gallery" of very interesting, but little known, gambler's (mostly cheats) who worked for and with Soapy.
You can read more about (and order) my book,
