Tracy Johnson Mulroy, who helped carry on her family’s Thoroughbred racing and breeding operation at Virginia’s Legacy Farm, died Nov. 1, 2026, surrounded by family and close friends. She was 58.
Racing had been part of Mulroy’s family for four generations, beginning with her great-grandfather. As girls, she and her younger sister, Kelly, spent Saturday nights at Charles Town, watching the last race in their pajamas from the roof of the family car. When their father, R. Larry Johnson, died in 2025, the sisters continued his racing and breeding operation at Legacy Farm while racing under the nom de course of the Estate of R. Larry Johnson.

With Michael Trombetta as their trainer, the Estate has enjoyed a productive 2026. It has garnered stakes wins with Hark Theangelssing, Determined Kingdom, Noquestionaboutit, and Doubting Thomas.
A horse that Larry Johnson bred, Mindframe, was the only two-time Grade 1 winner on dirt in the US in 2025, winning the Churchill Downs and Stephen Foster Stakes. He earned laurels as the Mid-Atlantic Thoroughbred/The Racing Biz Top Midlantic-bred of 2025.
“It’s the pinnacle of my dad’s breeding success, and to see it happen, to see him reach what he reached, it’s mind-boggling. That’s what my dad always dreamed of. It’s pretty surreal,” Mulroy said at the time. “It’s a dream, it’s just an absolute dream.”
Mulroy appeared on the Midlantic Racing Today podcast in March 2026 to discuss the challenges of taking over her father’s horse business.
“There’s pressure, but I think one of the things our dad always said was he was never afraid to swing for the fences,” she said then. “He liked to take those swings, and sometimes he missed, sometimes he hit, but I think it taught me to not be afraid to make mistakes. He made mistakes, and he’d been doing it for 50 years. So of course we’re gonna make mistakes, right?”
Mulroy grew up in Montgomery County, Md., and earned an economics degree from Franklin & Marshall College. She worked on the Consumer Price Index at the U.S. Bureau of Labor Statistics while attending Georgetown University Law Center at night. She went on to clerk for U.S. District Judge Emmet G. Sullivan and practice litigation at Arnold & Porter.
Born with osteogenesis imperfecta (OI), Mulroy served on the board of the Osteogenesis Imperfecta Foundation and helped establish the Jamie Kendall Fund for OI Adult Health in 2016 in memory of a close friend. The foundation gave her its President’s Award in 2018. She later became a certified mindfulness meditation teacher and taught within the disability community.
Among her survivors are her children, Reece and Laura Mulroy, her mother, Nita Johnson, and her sister, Kelly Caraballo. Memorial arrangements are pending. In lieu of flowers, the family requests donations to the Jamie Kendall Fund for OI Adult Health.
