A Kentuckian whom the kid meets while the two are incarcerated, along with Toadvine, in the prison in Chihuahua City, Grannyrat served in the Mexico-American War and was part of the force that sacked Chihuahua City during that conflict. Grannyrat joins Glanton’s gang, only to disappear from the gang soon after arriving in Janos. He is probably murdered by the Delawares as a deserter.
