Four Generations of Gold: The Mary Ann Miller Story
One family’s legacy proves that rodeo isn’t just a sport. It’s a bloodline.
Written by Dee Yates | Publisher & Editor-in-Chief, Ropers Sports News
There are families in rodeo who carry the sport in their bones, where world championships aren’t trophies on a shelf but milestones in a living legacy that stretches back before there was even an official organization to crown a champion.
Mary Ann Miller is the fourth generation of that kind of family. Ask her about it and she’ll redirect you to her father, her uncle, her great-grandfather, anybody but herself. That’s just who she is. Humble to a fault and generous to a fault. But this is the Women’s Rodeo Issue, and Mary Ann isn’t getting out of this one. Because when you trace the line from the Oklahoma ranches of the early 1900s to the modern arena where women are finally being recognized for their grit and talent, Mary Ann stands right at the center of it all.
The Bloodline
It starts with Ben Johnson Sr., born in Harrison, Arkansas, in 1896. He became the foreman of the famed 70,000-acre Chapman-Barnard Ranch outside of Pawhuska, Oklahoma, in what was then Osage Territory, a position he held for seventeen years until his death in 1952. In the 1920s, before rodeo had formal structure, he won the championship at Cheyenne Frontier Days three times, in 1922, 1923, and 1926. He set a world record in calf roping in 1923 and a steer roping record in 1927, and was crowned world champion in 1922. There were no press tours. He won, went home, and went to work. He was inducted into both the Rodeo Hall of Fame and the Hall of Great Westerners at the National Cowboy and Western Heritage Museum in 1961.
His son, Ben Johnson Jr., got his start on that same ranch and became a legend in both rodeo and Western film. He won the 1953 RCA World Championship in team roping and later earned an Academy Award for Best Supporting Actor in The Last Picture Show, making him the only person in history to have won both a world rodeo championship and an Oscar. He was inducted into the ProRodeo Hall of Fame in 1979. To the public, he was a ten-foot-tall man of honor on the silver screen. To Mary Ann, he was Uncle Ben, the patriarch who carved the turkey at Thanksgiving and Christmas, who filled the role of grandparents she never got to know.
The third generation belongs to Mary Ann’s father, John Miller, born in McAllen, Texas, in 1942. John won back-to-back world champion team roping titles in 1970 and 1971, roping with John Bill Rodriguez and Ace Berry respectively. He won the National Finals team roping championship in 1973, was the PRCA reserve world champion steer roper in 1972 and 1973, and took roping titles at Cheyenne, Salinas, Tucson, and beyond. Inducted into the ProRodeo Hall of Fame alongside Uncle Ben in the inaugural class of 1979, John also served as resident trainer at the Lazy E Ranch and Arena in Guthrie, Oklahoma for a decade. There, he built the performance horse program from the ground up, with eleven horses qualified in a single year, many tracing back to a stud named Zan Par Jack. Still considered by many to be the best teacher of team roping alive, he practices every day at his place in Cave Creek, Arizona, where he lives with his wife Barbara, a National Finals Rodeo barrel racer.
And then there’s Mary Ann. Fourth generation. Two-time WPRA World Champion in heading, 2006 and 2007. Some have questioned whether the WPRA title counts. Her answer is simple: “There are two professional rodeo associations that have been around for seventy-five-plus years. I think it counts.”
It counts. And no other family in rodeo history can claim four consecutive generations of world champions.
Raised by Legends
Mary Ann was at a rodeo before she could walk. Two weeks old, tucked into the front seat of a single-cab pickup, headed to watch her dad trip steers. She ran barrels as a kid but didn’t start roping until fifteen, and the first steer she ever roped was in the practice arena at the Lazy E.
It was during those Lazy E years that twelve-year-old Mary Ann got her first real job, a role in one of Ed Gaylord’s early film productions that earned her a SAG card. On set, she was surrounded by Uncle Ben, her father, Buck Taylor, Jeff Osterhage, Morgan Woodward, Doug McClure, Richard Farnsworth, Wilford Brimley, and Rex Lynn.
“To me, they were just good people,” Mary Ann says. “They were family. It was hard for me to go out in the world because other people aren’t like that. They aren’t true blue. They aren’t salt-of-the-earth cowboys that worked for a living. After being around all of that, hanging out with a bunch of fourteen-year-olds at an after-school function wasn’t exciting to me.”
The Hat on the Hay Bale
In 1985, Ben Johnson Jr. founded the Ben Johnson Pro Celebrity Rodeo in Guthrie, Oklahoma, raising money for Children’s Medical Research, Inc. John Miller connected Uncle Ben with Ed Gaylord, and together they brought rodeo legends and country music stars to the Lazy E for something far bigger than competition.
The events brought in children with special needs, kids who arrived on buses in cowboy hats and bandanas, all dressed up for Rodeo Day. Some could not speak. Some could not walk. And these big, tough cowboys were wheeling kids in wheelchairs, lifting them onto hay bales, giving them hayrides around the arena. Country stars like LeAnn Rimes, Josh Turner, and George Strait came through. Uncle Ben’s last event was in 1995, co-hosted with Reba McEntire at the Lazy E. He passed away on April 8, 1996, from a heart attack while visiting his mother in Mesa, Arizona.
But it was one quiet moment at those events that cracked Mary Ann’s heart open and never let it heal back the same.
“My Uncle Ben took his hat off and set it on one of these little kids,” she says. “If you know how old cowboys feel about their hats, it’s hard to explain. But he put it on that child. And that was it. We all lost it.”
Even in the end, when he was sick and should have been home resting, Uncle Ben never turned anyone away. He signed every autograph. He took every picture. “That is how every successful person is supposed to be,” Mary Ann says. “If you can’t be a good person, whether you’re successful or not, it doesn’t matter what you achieve in life.”
The Miller Johnson Foundation
Years as an insurance adjuster showed Mary Ann a side of Western families most people don’t see. Hardworking people who did everything right, clocked in, clocked out, paid their taxes, and still couldn’t afford livable homes, with insurance that wasn’t going to fix it. Paired with what she’d witnessed through Uncle Ben’s charitable events, the frustration built into a promise: whenever she could, she would help.
In 2023, she launched the Miller Johnson Foundation with a clear purpose: to support the financial health of Western heritage families. Through the foundation, Mary Ann puts on ropings and community events, supported by Tito’s Handmade Vodka and a network of private donors and fellow ropers who believe in what she’s building. The foundation responds to emergencies when a competitor is injured or a family loses their home, while simultaneously supporting events that give women more places to compete and more money to win.
“I see so many people that need help that nobody’s willing to help,” she says. “The people that have the least give the most. And that has always driven me.”
The Miller Johnson Foundation is Mary Ann’s way of carrying Uncle Ben’s legacy forward, not with celebrity events and arena lights, but with quiet, consistent generosity toward the families who keep this sport alive.
Changing the Game for Women in Rodeo
When Mary Ann first approached Tito’s Handmade Vodka about entering rodeo, she had a simple pitch: if you want to stand out, support the women. Nobody else was doing it. Virtually no one in Western sports was directing sponsorship dollars specifically toward female competitors, and Mary Ann thought that was a missed opportunity of historic proportions.
She understood what the rest of the industry was slow to see. Women make eighty-six percent of household buying decisions. They’re buying the tack, the feed, the trailers, the trucks. When you invest in women, you don’t just get the cowgirl. You get the family unit.
Before Mary Ann brought Tito’s to the attention of the rodeo world, the brand had no involvement in the sport at all. She was the catalyst, and built the bridge between one of America’s best-selling spirits and an industry that was starving for corporate support of its female athletes. Tito’s became the official vodka partner of the Women’s Rodeo World Championships, supporting major breakaway events and the National Finals of Breakaway Roping over four incredible years. This year, the WRWC has been transformed into Premier Women’s Rodeo, now known as the PWR, and Tito’s continues to stand behind the women of rodeo as a proud sponsor of this new chapter. Every year, the caliber and number of cowgirls who show up continues to grow.
I see it every time I’m at a rodeo: a young woman holding a big check and a bigger buckle, and behind her on the banner is the Tito’s name. That is life-changing money for that young lady. She’s investing in her future, and the sponsors who made it possible are becoming part of her story forever. Other brands like Kimes Ranch have also stepped up in meaningful ways, and together they’re proving that investing in women’s rodeo isn’t charity. It’s smart business and good stewardship of the sport.
The better the funding, the better the competition, and the more fans, families, and future champions show up. Women aren’t just benefiting from this growth. They’re driving it. When the moms are competing, the kids are too, and that means another generation keeping Western heritage alive. The whole industry rises when women are supported, and Mary Ann Miller understood that before most of the industry caught on.
“When I was rodeoing full-time, young girls would come up wanting autographs,” she recalls. “It was hard for me to encourage them if I didn’t do something to make it better for them.” She did something about it. And the landscape is different because of it.
Just Getting Better at Being Mary Ann
When I ask what the future holds, Mary Ann doesn’t talk about titles. She talks about family. She wants to document their history for five nephews who don’t yet know the stories, the blizzard their great-grandmother rode through on a young colt to get medicine for a dying Ben Johnson Sr. and his baby. She wants them to know why Missouri feels like home even though none of them have lived there. She wants them to have the chance to be the fifth generation of world champions if they choose.
“I just want to get better at being a good Mary Ann Miller,” she says. “The best sister, the best daughter, the best friend I can be. I want to be a blessing to others. There’s more to life than winning a hundred world championships.”
Four generations of world championships live in this family’s story. But ask Mary Ann what makes her proudest, and it’s not the buckles. It’s the hat on the hay bale. It’s the father who won the world and went home to frame houses. It’s the uncle who signed every autograph, even when he was dying, and the amazing mother that put her own rodeo dreams on hold to give Mary Ann an opportunity to be the fourth generation world champion.
“It’s my mother Barabara who is the real champion.”
And Mary Ann Miller, fourth generation world champion, foundation builder, industry catalyst, and quiet force for change, is exactly who her family raised her to be.
