Before Mark Williams ever set foot in Cameron Indoor Stadium, his older sister Elizabeth had already made the place famous. Elizabeth Williams played at Duke from 2011 to 2015, was selected fourth overall in the 2015 WNBA Draft, and built a long professional career. Mark grew up watching her dominate from the stands. He knew what Duke blue looked like up close before he ever wore it.
Mark Oluwafemi Williams was born on December 16, 2001, in Norfolk, Virginia, to Margaret and Dr. Alex Williams — both of Nigerian descent. His father is a physician specializing in gastroenterology. The family name, Oluwafemi, means “God loves me” in Yoruba. In the Williams household, basketball wasn’t an abstract dream — it was a family tradition with a professional pedigree and an academic backbone.
Williams began his high school career at Norfolk Academy, a private school in his hometown. By the time he was a junior, he was averaging nearly 20 points, 11 rebounds, and close to 4 blocks per game, passing the 1,000-point threshold before his senior year. He transferred to IMG Academy in Bradenton, Florida — the elite sports boarding school — for his final prep season.
He was a McDonald’s All-American selection and was named to the Jordan Brand Classic (canceled due to COVID-19). Rated a five-star recruit by 247Sports and Rivals, Williams committed to Duke on November 1, 2019, choosing the Blue Devils over Michigan and UCLA. The family connection was undeniable, but Williams insisted the decision was about winning a national championship and modeling his game after former Duke center Wendell Carter Jr.
He arrived in Durham in the fall of 2020 — into the strange, empty-arena world of COVID basketball — as a 7-foot-1 freshman with a 7-foot-7 wingspan and the ambition to follow his sister’s footsteps through the same hallowed gym.
