April 10 is National Siblings Day. Unlike Mother’s Day or Father’s Day, it’s not officially recognized by the federal government. However, there is a movement afoot to make that happen. The Siblings Day Foundation notes on its website that 49 states recognize the day. The only state that hasn’t? California. covers California sports betting legalization efforts so we’re not prepared to lobby Gov. Gavin Newsom to sign a proclamation just yet. However, we were curious about which sibling athletes might be the most famous. Using Semrush, we tracked the total combined search volume between Feb. 28 and March 28, 2024 for siblings who are pro athletes. The top siblings should not be a surprise, considering that they’ve been in the news a lot recently, and not just for their football exploits.

Siblings With Cali Connections

We found that Travis and Jason Kelce are the most famous, and they have no connections with to The Golden State. But there are still several sets of famous brothers and sisters who have California ties.

For example, Jim Harbaugh is the new coach of the Los Angeles Chargers. And prior to leading Michigan to last year’s College Football Playoff national title, he worked the sidelines for Stanford and the San Francisco 49ers.

Steph Curry (pictured at the top facing brother Seth) has played his entire NBA career with the Golden State Warriors, helping to revive the franchise and make it into one of the league’s top teams. The league’s all-time 3-point scoring champion has also led the Warriors to six appearances in the NBA Finals, with four championships.

Williams Sisters Lone Women On List

Venus Williams started her journey to becoming a tennis legend in Florida with her sister Serena, but Venus was born in Lynwood, in Los Angeles County.

The Ball Brothers were all born in Anaheim, making names for themselves initially in high school. LaMelo is currently the only active brother in the NBA, but the Charlotte Hornets announced this week that his season would end prematurely due to an ankle injury. The 2021 NBA Rookie of the Year averaged 23.9 points in 22 games this season with the Hornets.

While LaMelo is out, his older brother Lonzo might be ready to make a comeback. Lonzo last suited up in January 2022 and a knee injury has kept him off the court since. However, reports last month indicated that he’s beginning to run and jump, signs that indicate he could come back with the Chicago Bulls sometime next season.

Rounding out the top 10 are the Lopez Twins, former California high school and Stanford basketball stars who have fashioned lengthy NBA careers for themselves. Brook and Robin, both of whom turned 36 on Monday, have more than 2,000 league games between them. Brook has had the most success and continues to start at center for the Milwaukee Bucks, averaging 12.3 points per game. Robin was his backup for part of this season until the Bucks traded him two months ago to Sacramento, where the Kings and subsequently waived him.
