Matching Barbie costumes, mesh gloves and a pair of brothers channeling Richard Simmons filled Glen Chamberlin Park last weekend as Twinsburg, Ohio hosted its 51st annual Twins Days Festival, an 1980s-themed gathering that pulled twins from as far as Arizona, Kansas City and Massachusetts. The festival's Double Take Parade rolled through town on August 8, capping a weekend built around a theme organizers called “Totally Two-bular!” to honor 1980s pop culture, fashion and music.
The event, recorded by Guinness World Records as the largest annual gathering of twins on the planet, typically draws between 2,000 and 3,500 sets of twins each year, according to the Twins Days Festival. Since it began, the festival has hosted more than 91,000 sets of multiples from all 50 states and over 35 countries. This year's crowd included Terri Jelinek and Tracy Renbarger, both of Arizona, who dressed as twin Barbies, and Kansas City's Rose Nafziger and Shelley Trantham, who made the trip to Northeast Ohio for the celebration, as reported by The Detroit News.
A Parade Full of 80s Throwbacks
Steve and Jeff Nagel of Dayton channeled Richard Simmons for the parade, while Courtney and Brittany Arnold of Mechanicsburg, Pennsylvania showed off 1980s mesh gloves as part of their look. Linda Harold and Lorie Loyacona, twins from Murrysville, Pennsylvania, took a different route entirely, dressing as long-lost Titanic survivors. Monica Mitchell of Columbus and Monic Harrish of Atlanta built their outfits around the decade's theme as well, per the same Detroit News account.
Sixteen-year-old Kennedy Bryant of Twinsburg served as a grand marshal of the festival alongside her twin, Kendall Bryant. Jen and Sarah Caban traveled from Waltham, Massachusetts to join the festivities, and Nick and Jim Colachis brought along a dog named Shadow. Anniece Johnson and Janniece Curry, both 90.5 years old as of the festival weekend, earned honors as the oldest twins on hand, the report notes.
Cornhole, Volleyball and 40 Years of Friendship
The weekend's programming stretched beyond the parade itself. Kevin and Andy Verhoef showed off medals they'd won in the festival's cornhole competition, and organizers also ran a volleyball tournament as part of the schedule. Doreen McConaghy, Donna Hyson, Dianne McConaghy, Fred Mitchell, Debbie Zawacki and Ned Mitchell, a group that has known each other for 40 years, gathered at the festival as well, according to the same account.
A Town Named for Twins, and the History Behind It
Twinsburg's connection to twins runs deeper than one weekend of costumes and cornhole. The town was originally called Millsville until 1819, when identical twin brothers Moses and Aaron Wilcox bought 4,000 acres of land and offered six acres for a public square plus $20 toward a school on the condition the settlement be renamed after them, according to the Twinsburg Area Chamber of Commerce. As Smithsonian Magazine has reported, Twinsburg is believed to be the only city in the world named specifically after its twin founders.
The Wilcox brothers' story took an eerie turn later in life. Moses and Aaron held all property in common, married sisters, had the same number of children, fell ill with the same unidentified disease, and died within hours of each other in 1827, and they were buried together in the same grave at Twinsburg's Locust Grove Cemetery, per Business Insider's account of the town's history.
The festival itself traces back to the 1976 U.S. Bicentennial, when a local committee held a flag-raising and picnic honoring the Wilcox twins that drew 36 sets of twins. That modest tribute prompted organizers to launch an expanded weekend festival the following year, one that has grown into the record-setting event held annually in Glen Chamberlin Park.
Millions in Economic Impact, and a Rare Research Opportunity
The festival's reach now extends well beyond nostalgia and matching outfits. An economic impact study by a Kent State University economist found that the Twins Days Festival injects more than $5.4 million into the local economy each year, largely from non-local visitors spending on hotels, restaurants and retail across the Cleveland-Akron area, according to WKBN.
That concentration of identical twins in one place has also made the festival an unusual draw for scientists and federal investigators. Since 2008, the FBI's Criminal Justice Information Services Division and West Virginia University have run an on-site research pavilion known as Research Row, collecting facial, fingerprint, iris and hand geometry scans from hundreds of identical twins, as detailed by Biometric Update. Because identical twins share nearly identical facial structures but retain unique fingerprints and irises, they offer a rigorous test for biometric identification tools.
Academic and corporate researchers make the same calculation. Institutions including the National Institutes of Health, the Monell Chemical Senses Center and Procter & Gamble regularly treat the festival as a live laboratory, studying genetics, skin aging, taste sensitivity and auditory processing among attendees, according to CNN. Geneticists can gather a year's worth of controlled trial data in a matter of hours given the thousands of identical and fraternal twin participants on hand.
Support for Twinless Twins
Not every part of the weekend is about parades and prizes. The festival also runs dedicated programming for so-called Twinless Twins, those who have lost a sibling, including an informal meet-and-greet area, a memorial photo board and an annual Saturday evening luminary lighting ceremony held at an octagonal pavilion behind the festival's arts and crafts section, per the Twins Days Festival.
The gathering's continued growth stands somewhat apart from national trends. A CDC National Vital Statistics System report released in June found the U.S. twin birth rate fell 2% in 2024 to 30.1 per 1,000 total births, continuing a decade-long decline from a peak of 33.9 per 1,000 in 2014. Even so, attendance at Twinsburg's festival has remained robust, with thousands of twin pairs still making the annual trip to Glen Chamberlin Park each August.
