Mark Williams comes from a close-knit Nigerian-American family with strong connections to education, medicine and basketball. The Phoenix Suns center was born in Norfolk, Virginia, to Nigerian parents Dr. Alex Williams and Margaret Williams and grew up in the Virginia Beach area alongside his two older sisters, Victoria Oloyede and WNBA star Elizabeth Williams.
Basketball became especially important in the Williams family through Elizabeth, who established herself as one of the best players in Duke women’s basketball history before becoming a first-round WNBA Draft pick. Mark eventually followed his sister to Duke and then reached the NBA himself. Away from basketball, however, Williams keeps his romantic life extremely private. Here is what is publicly known about Mark Williams’ girlfriend, children, parents and siblings.
Who Is Mark Williams’ Girlfriend?
Mark Williams does not have a publicly confirmed girlfriend as of now.
The Phoenix Suns center has kept his dating life almost entirely outside the public spotlight. His interviews and official profiles generally focus on basketball, injuries, his professional development and his relationship with his family rather than romantic relationships.
No reliable NBA, Duke or major mainstream sports source currently identifies a girlfriend or partner for Williams.
This does not necessarily mean Williams is single. He may simply prefer to keep his relationships private. Without confirmation from Williams himself or credible reporting, it would be inappropriate to identify anyone as Mark Williams’ girlfriend based on rumors or unsupported social-media claims.
Is Mark Williams Married?
There is no reliable public confirmation that Mark Williams is married.
Williams has not announced a marriage, and his official NBA biography does not identify a wife or spouse.
As of now, the publicly documented side of his personal life continues to center primarily on his parents and two older sisters.
Does Mark Williams Have Children?
There are no publicly confirmed reports that Mark Williams has children.
The Suns center has not publicly announced becoming a father, and authoritative profiles do not identify him as having a son or daughter.
Given Williams’ preference for privacy away from basketball, claims about children should not be treated as fact without reliable confirmation.
Who Are Mark Williams’ Parents?
Mark Williams’ parents are Dr. Alex Williams and Margaret Williams.
Both of his parents are originally from Nigeria. The family eventually settled in Virginia, where Mark and his sisters were raised.
Duke University and the NBA both officially identify Alex and Margaret as Mark’s parents.
The Williams household placed considerable emphasis on education. Mark’s father built a career in medicine, while his sister Elizabeth excelled academically alongside her basketball career at Duke.
Mark Williams’ Father: Dr. Alex Williams
Dr. Alex Williams is Mark Williams’ father. He is originally from Nigeria and built a successful medical career after moving abroad.
Duke reporting about the Williams family explains that Alex and Margaret left Nigeria while Alex pursued medical training.
The family spent time in England, where Mark’s sister Elizabeth was born, before eventually moving to the United States.
After arriving in America, Alex completed additional medical residency training and fellowship work before establishing his career in Virginia.
What Does Mark Williams’ Father Do?
Dr. Alex Williams is a physician specializing in gastroenterology.
During Mark’s time at Duke, university material identified his father as a practicing gastroenterologist in Chesapeake, Virginia.
Alex’s medical career contributed to the strong educational expectations inside the Williams family.
Mark himself earned academic recognition while at Duke, including selection to the ACC Academic Honor Roll during his college career.
Although Alex was not a college basketball player, he had an athletic background in soccer. Elizabeth Williams has previously said that both she and her father played soccer before basketball became the sport that ultimately took her and Mark to the professional level.
Mark Williams’ Mother: Margaret Williams
Margaret Williams is Mark Williams’ mother.
Margaret is also originally from Nigeria and raised her three children alongside Alex after the family established itself in Virginia.
She has generally maintained a much lower public profile than her professional-athlete children, and authoritative basketball sources provide relatively little information about her personal career.
What is well documented is that Margaret and Alex remained closely involved in their children’s lives and regularly supported their athletic careers.
Elizabeth has described the Williams family as extremely close and explained that having her parents and siblings nearby was one reason she chose Duke University.
Mark Williams’ Nigerian Heritage
Mark Williams is American-born but has Nigerian heritage through both of his parents.
His full name is Mark Oluwafemi Williams, reflecting that Nigerian connection.
His older sister Elizabeth was born in Colchester, England, after their parents left Nigeria while Alex pursued his medical education.
The family subsequently moved to the United States and eventually settled around Virginia Beach.
Mark has therefore grown up with a combination of Nigerian family heritage and an American upbringing.
Who Are Mark Williams’ Siblings?
Mark Williams has two older sisters: Elizabeth Williams and Victoria Oloyede.
Both Duke University and the NBA officially list Elizabeth and Victoria as Mark’s sisters.
Mark is the youngest of the three Williams children. Victoria is the oldest, Elizabeth is the middle child and Mark is the youngest.
Of the two sisters, Elizabeth is much more publicly known because of her successful basketball career.
Mark Williams’ Sister: Elizabeth Williams
Elizabeth Williams is Mark Williams’ older sister and a longtime WNBA player.
Elizabeth was born on June 23, 1993, in Colchester, England, before the family moved permanently to the United States.
She became an outstanding high school basketball player at Princess Anne High School in Virginia Beach and developed into one of the most highly recruited prospects in the country.
Elizabeth eventually committed to Duke University, beginning a family connection to the Blue Devils that Mark would later continue.
Elizabeth Williams’ Career at Duke
Elizabeth became one of the greatest women’s basketball players in Duke history.
She played for the Blue Devils from 2011 to 2015 and became the first player in ACC history to record more than 1,900 points, 1,000 rebounds and 400 blocked shots.
Elizabeth earned Associated Press All-America recognition in all four seasons and became a four-time ACC Defensive Player of the Year.
She also excelled academically, studying psychology while earning ACC academic recognition.
Duke later retired her No. 1 jersey, with her parents, sister Victoria and younger brother Mark present for the ceremony.
Elizabeth Williams’ WNBA Career
After completing her Duke career, Elizabeth entered the 2015 WNBA Draft.
The Connecticut Sun selected her with the fourth overall pick.
She later became a WNBA All-Star and established herself as one of the league’s most respected defensive centers.
Elizabeth has played for several WNBA organizations during her professional career, including the Atlanta Dream, Washington Mystics and Chicago Sky.
The NBA currently identifies her as a Chicago Sky player in Mark’s official family biography.
How Elizabeth Williams Influenced Mark Williams
Elizabeth’s basketball career gave Mark a unique example to follow while growing up.
She was already becoming one of America’s best young basketball players when Mark was still a child.
Because they are approximately eight years apart in age, Mark had an opportunity to watch his sister experience elite high school basketball, college recruiting, Duke basketball and eventually the professional game before he had to make those decisions himself.
The siblings also trained together.
Duke shared footage during 2020 of Elizabeth and Mark working out on the basketball court together shortly before Mark began his own career with the Blue Devils.
By choosing Duke, Mark followed the same path his sister had taken nearly a decade earlier.
Mark and Elizabeth Williams Became a Rare Duke Basketball Sibling Pair
When Mark arrived at Duke in 2020, the Williams family gained an unusual distinction.
Elizabeth had already become one of the greatest centers in Duke women’s basketball history, while Mark began building his own reputation as a center for the men’s program.
Mark eventually became the 2022 ACC Defensive Player of the Year, giving both Williams siblings major defensive reputations during their Duke careers.
The two also followed one another into professional basketball, with Elizabeth reaching the WNBA in 2015 and Mark joining the NBA seven years later.
Mark Williams’ Sister: Victoria Oloyede
Victoria Oloyede is Mark Williams’ oldest sister.
She is approximately 13 years older than Mark and several years older than Elizabeth.
Unlike her younger siblings, Victoria did not pursue a high-profile professional basketball career and has maintained a considerably more private life.
Duke family profiles nevertheless consistently identify Victoria as part of the close family that supported both Elizabeth and Mark.
Victoria was also present alongside Mark and their parents when Duke retired Elizabeth’s jersey in December 2016.
Because Victoria is a private individual, details about her professional and personal life should not be filled in with unsupported information from celebrity biography websites.
How Close Is the Williams Family?
The Williams family has repeatedly been described as close.
When Elizabeth was deciding where to play college basketball, she specifically mentioned being able to remain near her family as an important reason for choosing Duke.
Virginia Beach is within driving distance of Duke’s campus in Durham, North Carolina, allowing Alex, Margaret and the other Williams siblings to attend games.
Years later, Mark made the same college choice.
Although his decision was based on his own recruitment and basketball goals, having already watched Elizabeth succeed at Duke gave him familiarity with the university and its basketball programs.
Mark Williams’ Childhood in Virginia
Mark Oluwafemi Williams was born on December 16, 2001, in Norfolk, Virginia.
He grew up primarily in the Virginia Beach area and attended Norfolk Academy for the first three years of his high school career.
Williams gradually emerged as one of the country’s most promising centers thanks to his exceptional height, wingspan, mobility and rim protection.
He also competed for Team Boo Williams on the Nike EYBL circuit.
During the 2019 Peach Jam, Williams averaged more than 20 points and 12 rebounds while shooting at an exceptionally efficient rate from the field.
Mark Williams’ Final High School Season at IMG Academy
For his senior season, Williams transferred from Norfolk Academy to IMG Academy in Bradenton, Florida.
The move allowed him to compete every day against other elite basketball prospects.
Williams finished his high school career as a four-star prospect ranked among the leading centers in the 2020 recruiting class.
He was selected as a 2020 McDonald’s All-American, although the game was ultimately canceled.
Williams received scholarship interest from several major programs before committing to Duke on November 2, 2019.
Mark Williams’ Career at Duke
Williams played two seasons at Duke from 2020 to 2022.
His role increased dramatically during his sophomore season under legendary coach Mike Krzyzewski.
Williams became one of college basketball’s best interior defenders and finished the 2021-22 season averaging 11.2 points, 7.4 rebounds and 2.8 blocks per game while shooting more than 72 percent from the field.
He was named the ACC Defensive Player of the Year and earned Third-Team All-ACC and ACC All-Defensive Team honors.
Williams also played an important role in Duke reaching the 2022 Final Four during Coach Krzyzewski’s final season.
After two years at Duke, he declared for the NBA Draft.
Mark Williams’ Journey to the NBA
The Charlotte Hornets selected Mark Williams with the 15th overall pick in the 2022 NBA Draft.
He gradually established himself as Charlotte’s starting center, using his size and length to become an efficient scorer, rebounder and rim protector.
Williams’ early NBA career was also affected by injuries, limiting the number of games he was able to play during his first several seasons.
One of the most unusual moments of his professional career occurred in February 2025 when Charlotte agreed to trade him to the Los Angeles Lakers.
The trade was later rescinded, sending Williams back to Charlotte.
He finished the season with the Hornets before another trade finally moved him to the Western Conference.
Mark Williams Joins the Phoenix Suns
During the 2025 NBA Draft, Charlotte traded Mark Williams to the Phoenix Suns.
The move gave Phoenix a young starting center capable of finishing around the rim and providing a lob target for Devin Booker.
Williams produced his healthiest season to that point during 2025-26, appearing in a career-high 60 games and starting 55 of them.
He averaged 11.7 points and 8.0 rebounds per game while shooting approximately 64 percent from the field.
Phoenix subsequently made retaining Williams one of its priorities during the 2026 offseason.
Mark Williams Signs a New Suns Contract
In June 2026, Williams agreed to remain with Phoenix on a new contract.
The Suns officially announced the agreement in July, with Williams signing a three-year, $38 million contract.
The deal gave Williams additional stability after several seasons complicated by injuries and trade uncertainty.
As of now, NBA.com lists the 7-foot-1 Williams as Phoenix’s No. 15 center.
