Louis Toadvine—just simply called Toadvine—is a horse thief and felon in the Glanton Gang. He was branded with the letters HT—meaning Horse Thief— and F, meaning Felon. 
The other members of the Glanton Gang include Glanton (the leader), Judge Holden (the co-leader), The Kid, Tobin, Black Jackson, and the Delawares. 
The Judge is particularly disliked by Toadvine because the judge is a chıld predator and much more ruthless than Toadvine is.
The current year is also 1849
