In 2016, Steve Stone co-founded the BHBA, a private company located in Vernal, Utah. He saw a need for a DNA registry for bucking horses, something similar to what the Professional Bull Riders (PBR), American Bucking Bull, and stock contractors had created for bucking bulls. He started tracing bloodlines of top bucking horses provided by rodeo producer Sankey Pro Rodeo, and stock contractor Tooke Bucking Horses. While researching, he noticed the recurrence of Sankey's foundation bucking horse sire, "Custer", who died in 1994. Custer was a better sire of bucking horses than he was a bucking horse, and had sired strong quality athletes with longevity. Stone also discovered that some 30 head of the bucking horses used for the 1996 National Finals Rodeo (NFR) were descendants of Custer, and at least 15 were provided by Sankey. Custer was thought to be sired by Gray Wolf, one of the stallions in the Tooke's bucking horse string. After the BHBA was founded, the remains of Custer and Gray Wolf were exhumed in order to register their DNA. It was then discovered that Gray Wolf was not the sire of Custer, rather it was Timberline, another stallion in the Tooke's string.
