No, Alan Williams and Mark Williams are not related by blood, family history, or ancestral origin.
While both professional athletes share an identical last name and have played the center position for the same franchise, they come from completely distinct backgrounds.
Alan Williams grew up in the Southwest as the son of prominent public servants in Arizona, whereas Mark Williams was raised on the East Coast by Nigerian immigrant parents.
The connection between them is purely a coincidence of name, timing, and overlapping professional stops rather than any shared familial lineage or genetic connection.
Why Do Fans Think Alan and Mark Williams Are Related?
It is incredibly easy to see why basketball fans constantly confuse the generational lineages of these two physical big men.
The primary driver of the confusion is their mutual connection to the Phoenix Suns, a team where both players established meaningful portions of their professional profiles.
Alan Williams built his reputation in the desert a decade ago, leaving a lasting impression on the community with his energetic play style.
Years later, Mark Williams arrived in the very same city via a major trade, instantly taking over the modern interior duties for the organization.
This rare occurrence of two unrelated frontline players sharing a surname on the exact same franchise roster naturally sparked widespread rumors regarding a potential brotherly or cousin connection.
Mark Williams: Career Profile and Phoenix Suns Rise
Understanding the distinct trajectory of Mark Williams helps clarify his independent background. The following breakdowns detail his specific path from elite prospect to a vital piece of an interior rotation.
Background and Duke University Stardom
Born on December 16, 2001, in Norfolk, Virginia, Mark Williams was raised in a highly academic and athletic household by his parents, Margaret Williams and Dr. Alex Williams. He chose to stay close to the Atlantic coast for college, attending Duke University.
During his time under the national spotlight with the Blue Devils, his elite interior defense earned him the prestigious 2022 ACC Defensive Player of the Year award, setting the stage for his entry into the professional ranks.
Draft Pedigree and Charlotte Hornets Era
The Charlotte Hornets recognized his massive structural upside, selecting him 15th overall in the first round of the 2022 NBA Draft.
During his early developmental seasons in Charlotte, he proved to be an efficient double-double threat when healthy, showcasing excellent rim-running capability and defensive instincts.
His high-percentage finishing around the basket quickly solidified his reputation as one of the premier young traditional centers in the Eastern Conference.
The Trade to the Phoenix Suns and Extension
In June 2025, a major blockbuster deal completely reshaped the interior landscape of the league. The Phoenix Suns acquired the young center from the Hornets in exchange for a package centered around draft capital.
He made 60 appearances (including 55 starts) for Phoenix during the 2025–26 season, recording averages of 11.7 points, 8.0 rebounds, and 1.0 assists.
Recognizing his immense value to their long-term core, the front office locked him up securely in June 2026, signing him to a fully guaranteed three-year, $38 million contract extension.
Real Elite Basketball Family Connections
While he possesses absolutely no biological link to Alan, he does belong to a genuine professional basketball dynasty. His older sister is Elizabeth Williams, an elite defensive anchor and long-time star in the WNBA.
Elizabeth was selected 4th overall in the 2015 WNBA Draft, making the Williams siblings one of the most accomplished modern basketball pairings in the United States.

The UC Santa Barbara Legacy and “Big Sauce”

Despite going undrafted in 2015, his relentless motor and physical style earned him the beloved nickname “Big Sauce.”
He eventually signed a contract with his hometown Suns, quickly turning into an absolute fan favorite from 2016 to 2018 due to his high-energy rebounding off the bench.
