About Lady Dyanaformer
Lady Dyanaformer is deeply connected to the Horse Husband Stables legacy. Not only was she the first foal ever bred by Horse Husband Stables, but she also became their first racehorse.
Her dam, Lady Macjazz, still lives on the farm in retirement, making this a truly multi-generational story.
This will be her second foal—her first, Lord Paycasso, was born last year. Now, with a foal by Dubai World Cup winner Country Grammer on the way, all eyes are on what the next chapter holds for her growing family.

From his early days as a $450,000 two-year-old purchase, Country Grammer showed promise. He broke his maiden as a juvenile in New York and went on to win or place in 10 graded stakes races throughout his career. His victories include a 4 ½-length score in the San Antonio S. (G2) and a win in the Peter Pan S. (G3) over Mystic Guide, another future Dubai World Cup winner.
A Pedigree Built for Greatness
As a son of Classic winner Tonalist and from the esteemed Chris Evert family, Country Grammer carries a bloodline proven to produce elite runners. His pedigree includes Grade 1 winners Obligatory, Etoile Montante, Starformer, and Bonny South, making him an exciting stallion prospect.
📢 “On pedigree as well as performance, Country Grammer is absolutely entitled to sire an elite runner like himself, and you can’t say that of many horses standing at this kind of money.” – Chris McGrath, TDN
First Foals in 2025
With his first foals arriving in 2025, Country Grammer is an exciting young sire with the potential to pass on his toughness, stamina, and championship pedigree.
Lady Dyanaformer’s upcoming foal by Country Grammer will be her second foal, following her first colt, Lord Paycasso, who was born in 2024. As the first homebred racehorse for Horse Husband Stables, Lady Dyanaformer’s legacy continues with this special pairing.
