Sibola.

About Sibola

Sibola (1896–1921) was an American-bred, British-trained Thoroughbred racehorse and broodmare. She was sent to England as a yearling and showed some promise as a two-year-old in 1898 although she failed to win a race. In the following year, she was the most successful filly of her age in England, taking the Wood Ditton Stakes, 1000 Guineas, Derby Biennial Foal Stakes and Scarborough Stakes as well as finishing a close and unlucky second in the Epsom Oaks. She remained in training until the age of five but never recovered her best form. As a broodmare she had an enduring influence on the breed as the female-line ancestor of Nearco.
