Rokeby Stables was an American thoroughbred racehorse breeding farm in Upperville, Virginia, involved with both steeplechase and flat racing.
Glint of Gold, a son of Mill Reef, won six European Group One races including the 1981 Derby Italiano, Grand Prix de Paris, and Preis von Europa.
In England, Mellon kept his horses at trainer Ian Balding's Park House Stables at Kingsclere and raced under his own name.
Miller's accomplishments include winning the New York Handicap Triple in 1984 with Fit To Fight and the 1993 Kentucky Derby with Sea Hero.
Once Miller retired from training, in 1995, the then 88-year-old Paul Mellon decided to give up racing but still maintained his breeding operations.
