“Windy” is a 2015 Kentucky-bred thoroughbred mare who was registered with the Jockey Club, a thoroughbred breed registry, as Princessdaisyleigh. Her sire is Graydar, the son of Unbridled’s Song – who won $1.3 million and was posthumously granted the title of leading sire in North America in 2017 – and grandson of 1990 Kentucky Derby winner Unbridled, who claimed almost $4.5 million in race earnings. Her dam is Cherry Sherry, a granddaughter of Canadian-bred Deputy Minister who sired many successful racehorses – a feat replicated by his son, and Windy’s grandsire, Awesome Again.
