Born in Chester, New York, Roy Miller was the son of Guy Miller, who worked for William Rysdyk as a young man and later bought Rysdyk's farm. Roy devoted his entire life to the sport as trainer, driver, track official, owner, steward, track manager and exporter of horses. Most of his career was spent in Lexington, Kentucky, where he operated a public stable. Miller won the Kentucky Futurity in 1903 with Grace Bond, and again in 1910 with Justice Brooke. Roy Miller died in 1952 in Lexington.
