I have just come across a small amount of material regarding Diamond-Tooth Lil that belonged to my great-grandfather. As a young man, he cowpunched out West and met her at that time. In fact, during a bar-room brawl at her establishment, he had the tip of his little finger shot off.
The material includes published items about her as well as a letter from an associate of hers to my great-grandfather in the late 1940s, as well as a letter from my g-g back to that associate recalling Lil.
