Trojan War (1948) a gelding by
Shut Out. Winner of two races. Owing to the success of her descendants, La Troienne was listed as a
Cluster Mare, which is a Thoroughbred brood mare that has produced two or more winners of five or more of the eight most important and valuable races, within six generations. When writing about American Classic Pedigrees in 2003,
Avalyn Hunter identified six winners of
American Triple Crown races descended from her in the female line: Bimelech,
Personality, Easy Goer, Sea Hero, Prairie Bayou, and Go for Gin, plus four winners of similarly prominent races for fillies:
Princess Rooney,
Lite Light, Pike Place Dancer and Tweedside.
Leading sire Tapit is a descendant of A.P. Indy on the male side, and has an additional four strains of La Troienne from his dam, Tap Your Heels. Similarly,
California Chrome, the 2014 Horse of the Year, traces to A.P. Indy on the male side, and has four additional strains of La Troienne through his dam, Love the Chase. Even
American Pharoah, the 2015
Triple Crown winner, has five strains of La Troienne, in his case through grand-sire
Empire Maker. La Troienne's influence is not limited to North America. For example, she appears in the pedigrees of both
Galileo and
Danehill,
leading sires in Great Britain and Ireland, through her great-grandson Buckpasser. The unbeaten
Frankel, who descends from both Galileo and Danehill, thus has two strains of La Troienne. La Troienne came in time to be described as "the most important producer to be brought across the Atlantic Ocean in [the twentieth] century." Pedigree expert Avalyn Hunter says she is "arguably the foremost American taproot mare of the modern era." ==Later life==
