He is first assigned to protect Chayton Black from the Sioux, but he is later promoted to the title of sheriff. He is voiced by Phil Hayes and is named after Kevin "The Sheriff" Holme, a veteran game developer of Ensemble Studios.
Billy Holme was a hardened Civil War veteran on the Union side who later became quartermaster of Fort Laramie.
"Sworn to preserve and protect, Sheriff Holme sees this territory as a land of conflict and opportunity. He's a survivor - a tour of duty during the Civil War has given him a gruff, sometimes jesting, view of life. With his long-time friend Chayton by his side, Holme is not a man to let events simply unfold for themselves."
After Chayton Black first meets him, they protect Miners and Settlers from Sioux raids successfully over the length of a year before parting ways. Ten years later, Chayton meets again with Holme (now a sheriff), who has discovered gold in the Black Hills of South Dakota and offers Chayton a partnership in the mine.
When the Americans claim this gold, tensions between the Sioux and American settlers erupt after the miners continue to invade Sioux lands to strip them of their resources. At first, Chayton allies with Holme, but, when Holme asks Chayton to raid a Sioux village and kill even women and children, Chayton refuses after realizing that his old friend has become corrupt and leads an attack on Holme's base. Holme flees, and Chayton searches for him with the help of native Sioux who discover him in a cave.
After killing his team of bandits armed with gatling guns, Chayton tries to convince Holme to stop attacking the Sioux villages (he had explained to Colonel Custer that it was Holme and not the Sioux that had begun the attacks), but Holme refuses and tries to kill Chayton with a quick shot from his pistol. Chayton draws his gun more quickly, however, and shoots the aging sheriff.
Mortally wounded, Holme stumbles backwards into some powder kegs before falling with them down a mine shaft, where said kegs explode. Chayton expresses disappointment at his former friend's decision and slowly walks away from the smoking hole.
As an American Civil War veteran, Sheriff Holme sees unsettled American territory as land of conflict and opportunity, and this has given him a gruff, sometimes jest, view of life.
This eventually leads him into a conflict with Chayton over the proper use of force against others. He eventually lets his greed get the better of him, however, and is shown to be uncaring about others when it comes to money-making.
He even tells Chayton in their final confrontation that he would have cruelly killed U.S. settlers in place of Native Americans if they had claim to the territory instead.
In the game, Holme wields a pistol and a rifle and can train Outlaw Riflemen but has no special attacks.
- Holme is shown to carry a rifle on his back, but it is never used. He uses his revolver in combat instead.
