[14] 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.
Beyond the success of her female line, La Troienne appears in the pedigrees of numerous other stakes winners, often through a form of inbreeding.
[17] Even American Pharoah, the 2015 Triple Crown winner, has five strains of La Troienne, in his case through grand-sire Empire Maker.
Pedigree expert Avalyn Hunter says she is "arguably the foremost American taproot mare of the modern era.
"[5] In 1938, at the age of 13, La Troienne was frightened by a thunderstorm and due to a loss of vision in her right eye, she bolted and collided with a tree.
A syndicate including Greentree Stables, King Ranch, and Ogden Phipps received La Troienne.
Churchill Downs then renamed the Louisville Distaff Handicap, for fillies and mares 3 years old and up, in La Troienne's honour.
[21] La Troienne never received the title of Kentucky Broodmare of the Year as her best foals raced prior to the creation of the award in 1946.
[3] La Troienne was sired by Teddy, who is commonly considered the best three-year-old of 1916 in France and Spain, although his racing career was disrupted by World War I.
Among his leading offspring were Bull Dog and Sir Gallahad III, who both became outstanding sires when imported into the United States.
Her dam, Lady of Pedigree, was a half sister to the notable broodmare Absurdity, who produced two Classic winners, Jest and Black Gesture.
Young Giantess produced a thriving family and literally hundreds of crosses to her accumulated in the pedigree of La Troienne.
Upon arrival in North America, La Troienne was bred to stallions who descended from this male line of Diomed.
Brinfield concluded, "Every foal from La Troienne was the result of the reunion of male and female strains of Diomed after segregation for over a century.
