Athletic enthusiasts have always recognized the heritage that particular families contribute to various playing surfaces and venues. In American football, we see the Kelce duo, the Manning dynasty, or the Harbaugh siblings commanding from the sidelines. Basketball showcases Reggie and Cheryl Miller, along with Steph and Seth Curry. Tennis witnessed Venus and Serena Williams rule an entire era and beyond.
Could it be hereditary? Perhaps environmental factors? Most likely it's a combination of both elements. Here's the emerging generation of siblings making their mark across different sports.
Jack, Luke and Quinn Hughes & Matthew and Brady Tkachuk
The 2026 Olympics will showcase family representation for Team USA, featuring two hockey dynasties competing for roster positions. The Hughes trio—Quinn, Vancouver's captain, alongside his sibling Jack, a New Jersey center—are contenders for the team. Young Luke, who also plays in New Jersey with Jack, shouldn't be overlooked either.
The Tkachuks are also preparing for Milano Cortina. Matthew, 27, secured consecutive Stanley Cup victories with Florida, while Brady, 26, leads Ottawa as captain. These wingers—offspring of U.S. Hockey Hall of Fame member Keith Tkachuk with 431 combined career goals—both participated in the 2025 4 Nations Face-Off for Team USA.
Lewis and Nicolas Hamilton
The Hamilton half-siblings share a passion for high-speed vehicles, though they excel on different racing circuits. Ferrari's Lewis launched his F1 journey with McLaren in 2007, capturing seven championships, matching the all-time record. Nicolas, born with cerebral palsy, made racing history in '15 as the first disabled competitor in the British Touring Car Championship. He raced in BTCC from '19 to '23, achieving a career-high sixth-place result, and resumed competition this season.
Ethan and Jackson Holliday
The Holliday siblings continue a family tradition established by their father Matt, a seven-time All-Star and 2011 World Series champion with St. Louis. Jackson, playing second base and shortstop, was Baltimore's first overall pick in the '22 MLB draft and played in the majors during the '25 campaign. Ethan topped MLB Pipeline's prospect rankings and was Colorado's fourth selection in July. The shortstop earned a record-breaking $9 million signing bonus for a high school player, following his brother's similar achievement three years prior.
Garrett and Colton Nussmeier
With Doug Nussmeier as their father—a former NFL quarterback currently serving as New Orleans' offensive coordinator—football runs through these brothers' bloodlines. Garrett, an LSU fifth-year senior, accumulated 4,052 passing yards and 29 touchdowns last season, entering this year among Heisman contenders (excluding the Manning category). Colton, quarterbacking at Marcus High in Texas, ranks as a consensus four-star 2027 recruit with scholarship offers from 20 elite programs including Alabama, Michigan, Texas Tech, and naturally, LSU.
Satou and Nyara Sabally
The Sabally duo, both selected in the WNBA draft's top five, competed together at Oregon and represented Germany in the 2024 Olympics. During her three seasons in Eugene, Satou, 27, guided the Ducks to their inaugural NCAA Final Four appearance in '19. Selected second by Dallas in '20, the three-time All-Star now plays for Phoenix. Nyara, 25, was chosen by New York in '22 and contributed to the Liberty's first championship last season, recording 13 points and seven rebounds in just 17 minutes during Finals Game 5.
Alyssa and Gisele Thompson
The Thompson duo continues breaking barriers. Following Alyssa's 2023 selection by Angel City FC—becoming the NWSL's first high school draftee—Gisele joined her sister in Los Angeles the following season. In May, 19-year-old Gisele netted her inaugural professional goal, assisted by her 20-year-old sister, marking the first sibling combination to achieve this feat in league history. The pair are also creating impact internationally: They both started for the USWNT this year, becoming only the second sister pair to accomplish this.
Dash and Dyson Daniels
These Australian siblings have perfected the art of theft on the court. Known as the Great Barrier Thief, Dyson topped the NBA in steals per game last season with 3.01 (ranking 11th all-time) while contributing 5.9 rebounds and 4.4 assists per contest. The 22-year-old earned NBA's Most Improved Player honors. Expected as a lottery selection in next year's draft, 17-year-old Dash has inherited the family's defensive instincts: The point guard topped the 2024 FIBA U-17 World Cup in steals per game with 3.6.
Jude and Jobe Bellingham
Sibling partnerships in English football present varied outcomes. Bobby and Jack Charlton guided the Three Lions to World Cup glory in 1966. Gary and Phil Neville anchored their nation's most frustrating era. The Bellinghams currently fall somewhere between these extremes—two dynamic, versatile midfielders who captivate audiences. Jude, 22, shines for Real Madrid; Jobe, 19, recently signed with Borussia Dortmund. They'll dedicate the coming decade to delivering another championship to England. Success would be remarkable to witness.
