In this July 17, 2018, photo, Bill Frank Brown walks to feed his horses on his farm in Poplarville, Miss. The farm had been in Brown's family since 1881 and the livestock there, even longer. Brown had three stallions back then, including DeSoto. He called them pine tacky horses. The Texas A&M veterinary school tested samples of the stallions' DNA, and they matched those of Rickman's Choctaws. (AP Photo/Gerald Herbert)
