Sir James Percy Miller, 2nd Baronet, DSO (22 October 1864 – 22 January 1906) was a British soldier, known as a racehorse owner.
[2][3][4] Miller was a Captain in the 14th Hussars from 1885 to 1892, and Adjutant from 1888 to 1892; and served in the Second Boer War from 1900 where in 1901 he was second in command of the sixth battalion, Imperial Yeomanry.
[1] His father's fortune, made from herring, allowed Miller to commission the complete rebuild of Manderston House as a stately home, near Duns, Berwickshire.
[7] The purchase was from Sir Robert Jardine and John Porter; Sainfoin had won the Esher Stakes at Sandown Park easily.
[1] Miller's next stroke was the purchase in 1894 for 4100 guineas, as a yearling, of the mare Roquebrune (foaled in 1893), by St. Simon, who had been bred by the Duchess of Montrose.
During the three seasons he was in training, the horse won stakes to the value of £45,618, and helped place Miller at the head of the list of winning owners in 1903 and 1904, with totals of £24,768 and £27,928 respectively.
His major success in handicaps was the victory in the Cesarewitch of 1898 with Chaleureux, the sire of the filly Signorinetta, who in 1908 won the Derby and Oaks for Edoardo Ginistrelli.
