Here is everything publicly known about Cormac Ryan’s girlfriend, children, parents and siblings.

Cormac Ryan’s Girlfriend: Is He Dating Anyone?

Cormac Ryan has not publicly confirmed the identity of a girlfriend. Despite becoming a recognizable college basketball player and subsequently joining the NBA, reliable information about his romantic relationships remains limited.

Throughout his basketball career, Ryan has primarily attracted media attention for his performances, leadership qualities, academic accomplishments and competitive personality.

During his years at Stanford, Notre Dame and North Carolina, he participated in numerous interviews discussing his basketball journey, family upbringing and experiences living in different parts of the United States.

However, those interviews generally did not provide details about his dating life.

There are no widely verified public reports identifying a current girlfriend or establishing that Ryan is involved in a romantic relationship.

Although he maintains a social media presence, his publicly documented activity does not provide sufficient evidence to identify a romantic partner.

As of now, Cormac Ryan’s relationship status remains publicly unconfirmed. This does not necessarily mean he is single, as he may prefer to keep his personal relationships away from public attention.

Is Cormac Ryan Married?

There are no credible public reports confirming that Cormac Ryan is married.

The Milwaukee Bucks guard has not made a widely documented wedding announcement or publicly identified anyone as his wife.

His official college and NBA biographies primarily discuss his basketball achievements, education, parents and siblings.

Consequently, there is insufficient verified information to establish that he has married.

Does Cormac Ryan Have Children?

There is no credible public information confirming that Cormac Ryan has children.

The professional basketball player has not publicly announced becoming a father, and his official basketball biographies do not identify a son or daughter.

Born in October 1998, Ryan entered professional basketball after completing an unusually long college career that included six academic years and five playing seasons.

His public interviews have generally concentrated on his athletic development, academic responsibilities and professional ambitions.

Although he has spoken about growing up with four siblings and maintaining strong family relationships, there are no verified reports confirming that he has become a parent.

As of now, Cormac Ryan has no publicly confirmed children.

Who Are Cormac Ryan’s Parents?

Cormac Ryan’s parents are Michael Ryan and Rosemary Ryan, both former student-athletes at Yale University in New Haven, Connecticut.

Their identities are confirmed in Ryan’s official University of North Carolina biography and the university’s previous basketball records.

According to Yale University’s official athletic biography for their eldest son, Thomas Ryan, Michael graduated from Yale in 1989, while Rosemary graduated in 1988.

The couple met while attending Yale and subsequently established their family in New York City.

They raised five children: Thomas, Cormac, Owen, Summer and Starling.

Competitive sports became an important part of the household, particularly because both parents had experience participating in college athletics.

Cormac Ryan’s Father: Michael Ryan

Michael Ryan, commonly known as Mike Ryan, is Cormac Ryan’s father and a former college basketball player at Yale University.

He attended Yale during the 1980s, competing on the university’s men’s basketball team while pursuing his education.

According to a December 2018 feature published by the San Francisco Chronicle, Michael played small forward and earned Academic All-American recognition.

His basketball background helped establish a strong sporting tradition within the family.

After completing his university education, Michael pursued a professional career outside competitive basketball while remaining actively involved in his children’s athletic development.

He became especially important to Cormac during childhood, regularly introducing him to basketball fundamentals and encouraging him to compete against older players.

In a March 2024 interview with WRAL, Michael and Rosemary discussed how basketball became a daily family activity during their years living in Manhattan.

The family attended St. Anthony’s Church, which had an attached school gymnasium.

According to Rosemary, the parish priest allowed the family to use the gym after normal school hours.

Michael frequently took Cormac, Thomas and their siblings to the facility after dinner, where they practiced shooting, ball handling and other basketball skills.

The sessions sometimes continued late into the evening.

Michael later described access to the gym as one of the most valuable opportunities the family had during the children’s development.

Those regular practices helped Cormac develop the shooting confidence and competitive mentality that would eventually define his basketball career.

How Michael Ryan Influenced Cormac’s Basketball Development

Michael Ryan’s influence extended beyond teaching his son how to shoot and dribble.

Growing up in New York City meant Cormac had access to different basketball environments, from organized youth leagues to outdoor playgrounds.

His father encouraged him to experience those different settings and compete against players with varying abilities.

In an interview published by the San Francisco Chronicle in December 2018, Ryan discussed how he started playing basketball at approximately seven years old.

His early experiences included participating in games at the Tony Dapolito Recreation Center in Greenwich Village, commonly associated with Carmine Street.

He later began competing in travel basketball programs when he was approximately nine.

Ryan also played in different parts of New York City, including Harlem, Brooklyn and the Bronx.

These experiences helped him develop confidence and learn how to compete against physically stronger and more experienced opponents.

His father’s basketball knowledge provided guidance throughout the process.

Michael also supported Cormac as he developed into a highly rated high school prospect and eventually accepted an opportunity to play at Stanford University.

His involvement continued through Cormac’s transfers to Notre Dame and North Carolina.

In March 2024, Michael and Rosemary publicly celebrated their son’s success with the Tar Heels, particularly his performance against Duke at Cameron Indoor Stadium.

Cormac Ryan’s Mother: Rosemary Ryan

Rosemary Ryan is Cormac Ryan’s mother, a former Yale University soccer player and social worker.

According to Yale Athletics, Rosemary graduated from the university in 1988, one year before her husband.

During her college years, she participated in competitive soccer, establishing her own athletic background before becoming a mother.

After marrying Michael Ryan, Rosemary helped raise their five children in Manhattan.

According to the San Francisco Chronicle, she initially concentrated on raising the children before later working as a social worker.

Her own experiences in college athletics helped her understand the demands of balancing education, training and competitive sports.

Alongside Michael, she encouraged her children to pursue their individual sporting interests.

Although basketball became particularly important to Thomas and Cormac, the family’s activities also included soccer, track and field, and other sports.

Rosemary frequently attended her children’s games and helped organize their activities while they were growing up.

In a March 2024 interview with WRAL, she recalled how the family regularly used the gym at St. Anthony’s Church in Manhattan.

Those evening training sessions became an important part of the children’s upbringing.

Her support remained significant as Cormac moved away from New York to attend Milton Academy in Massachusetts and later Stanford University in California.

Rosemary Ryan’s Support During Cormac’s College Career

Rosemary remained closely involved in Cormac’s basketball journey throughout his years in college.

She supported his decision to attend Stanford in 2018 and his subsequent transfer to Notre Dame in 2019.

When Cormac joined North Carolina in 2023, the family developed a strong connection to the Tar Heels basketball program.

In March 2024, Rosemary spoke with WRAL about her son’s experience in Chapel Hill.

She described the university’s basketball environment as exceptionally welcoming and expressed appreciation for the relationships her son had established with coaches, teammates and supporters.

Rosemary was also among the family members who celebrated Ryan’s memorable performance against Duke on March 9, 2024.

He scored a career-high 31 points in North Carolina’s 84–79 victory at Cameron Indoor Stadium.

The win helped the Tar Heels secure the outright Atlantic Coast Conference regular-season championship.

For Rosemary and Michael, the performance represented an important achievement after years of supporting Cormac’s basketball development.

Their involvement reflected the close relationship between Ryan and his parents.

Cormac Ryan’s Siblings: Meet His Two Brothers and Two Sisters

Cormac Ryan has four siblings: two brothers named Thomas and Owen Ryan, and two sisters named Summer and Starling Ryan.

He is the second oldest of the five children born to Michael and Rosemary Ryan.

All four siblings were identified in an October 2018 interview published by Stanford University Athletics.

During the interview, Cormac explained that growing up in a large family helped develop his competitive personality.

He described how the siblings regularly competed against one another in sports and other activities, creating a lively family environment.

Their shared enthusiasm for competition contributed to the development of several college athletes within the household.

Cormac Ryan’s Older Brother: Thomas Ryan

Thomas Ryan is Cormac Ryan’s older brother and a former college basketball player at Yale University.

Like their father, Michael Ryan, Thomas attended Yale and represented the university’s men’s basketball team.

According to his official Yale Athletics biography, Thomas attended Riverdale Country School in New York before completing his high school education at The Hotchkiss School in Connecticut.

During his high school basketball career, he scored more than 1,000 points, collected more than 600 rebounds and made over 200 three-point field goals.

He also helped Riverdale win its first conference championship in approximately 30 years and its first New York State Class B championship in 2013.

After graduating from high school, Thomas joined the Yale Bulldogs basketball program in 2015.

He represented the university through the 2018–19 season, becoming part of a successful period for Yale basketball.

During his collegiate career, Thomas appeared in 39 games and recorded 39 points and 11 rebounds.

Although he was primarily a reserve player, he received recognition for his commitment and dedication.

In 2017, Yale awarded him the Bill Madden Toughness Award.

He subsequently received the Josh Hill Dedication Award in 2018.

Thomas completed his Yale basketball career in 2019.

How Thomas Ryan Influenced His Brother Cormac

Thomas Ryan played an important role in helping Cormac understand the demands of college basketball.

Because Thomas was already competing at Yale when Cormac began attracting college recruiters, he provided valuable advice about balancing academics and athletics.

In an October 2018 interview published by Stanford Athletics, Cormac discussed the close relationship between the brothers.

He explained that he frequently spoke with Thomas about the responsibilities associated with playing college basketball.

Thomas also provided guidance during Cormac’s recruitment process.

His experience with Yale’s successful basketball program offered an example of what Cormac could expect at the NCAA Division I level.

During childhood, the brothers regularly practiced basketball together in New York City.

According to their parents, Thomas and Cormac were particularly enthusiastic participants in the family’s evening basketball sessions at St. Anthony’s gym.

Their shared experiences helped establish a strong relationship that continued as both pursued college basketball careers.

Cormac Ryan’s Brother: Owen Ryan

Owen Ryan is one of Cormac Ryan’s younger brothers and a member of the family’s five-child household.

His identity is confirmed in official player biographies published by Stanford, North Carolina, Yale and Haverford College.

Like his siblings, Owen grew up in Manhattan, where the family participated in different sports and recreational activities.

In a March 2024 interview with WRAL, Rosemary Ryan recalled that Owen occasionally joined his father and older brothers for evening basketball sessions at St. Anthony’s Church gym.

The sessions allowed the children to spend time together while improving their sporting skills.

Owen was also part of the competitive family environment that Cormac described during his Stanford interview.

Although Thomas, Cormac and Summer have well-documented college athletic careers, reliable information about Owen’s educational background, occupation and current personal activities remains limited.

There is also insufficient verified public information to establish whether Owen pursued college basketball or another sport.

Nevertheless, his involvement in the family’s childhood activities reflects the importance of sports within the Ryan household.

Cormac Ryan’s Sister: Summer Ryan

Summer Ryan is Cormac Ryan’s younger sister and a former college basketball and track-and-field athlete at Haverford College in Pennsylvania.

Like her brothers, Summer developed an interest in sports while growing up in New York City.

She attended Newton Country Day School of the Sacred Heart in Massachusetts, where she established herself as an accomplished multisport athlete.

According to her official Haverford Athletics biography, she played four years of varsity volleyball and earned multiple basketball honors.

Her accomplishments included three All-Eastern Independent League basketball selections and recognition as a Boston Globe Class C All-Star.

She also served as a team captain and was a member of a championship-winning youth basketball team in 2019.

After graduating from high school, Summer joined Haverford College.

She represented the college’s women’s basketball program, appearing on its official roster during the 2022–23 season.

Her involvement continued in track and field, where she competed in throwing and jumping events.

According to Haverford’s official 2024–25 athletics records, Summer competed in events including the shot put, javelin, high jump and long jump.

She received Centennial Conference Academic Honor Roll recognition and College Sports Communicators Academic All-District honors.

Alongside athletics, she studied neuroscience.

Her university biography also lists activities involving music, women’s club soccer and student organizations.

These achievements demonstrate that the Ryan family’s sporting tradition extends beyond basketball.

Summer’s experiences also reflect the family’s emphasis on combining education with competitive athletics.

Cormac Ryan’s Sister: Starling Ryan

Starling Ryan is Cormac Ryan’s younger sister and another of the five children born to Michael and Rosemary Ryan.

Her name is confirmed in Cormac’s Stanford Athletics interview and his official University of North Carolina biography.

She grew up in the same New York City household where basketball and other sports were important family activities.

During his 2018 interview with Stanford, Cormac described all five siblings as competitive individuals who enjoyed challenging one another.

Starling was included among the siblings whose personalities contributed to that family atmosphere.

However, unlike Thomas and Summer, Starling has maintained a relatively private public profile.

Reliable information about her current occupation, educational background or participation in college athletics remains limited.

Although she is publicly identified as Cormac’s sister, detailed aspects of her personal life have not been widely documented.

Cormac Ryan’s Grandparents and Family Basketball Heritage

Cormac Ryan’s extended family also played an important role in his introduction to basketball.

One particularly influential relative was his maternal grandfather, Tom McNicholas.

According to a March 2024 feature published by The News & Observer, McNicholas helped establish the family’s enthusiasm for basketball long before Cormac entered college athletics.

He began playing basketball at approximately 13 years old and maintained an interest in the sport throughout adulthood.

McNicholas participated in the Rockville Centre Over-40 basketball league on Long Island.

He began competing in the league at 52 and continued participating for more than two decades.

During some seasons, he even competed against his son, Tom McNicholas Jr.

His long involvement in basketball demonstrated the importance of the sport across multiple generations of the family.

In the same interview, Cormac expressed appreciation for his grandfather’s role in establishing the family’s basketball tradition.

His maternal grandmother, Veronica McNicholas, also spoke publicly about her grandson’s personality and family relationships.

She described Cormac as someone who demonstrated leadership among his siblings while maintaining close relationships with each of them.

These accounts highlight how Cormac’s upbringing was influenced not only by his parents but also by his extended family.

Cormac Ryan was born and raised in Manhattan, New York City, where his family lived in the SoHo and Greenwich Village areas.

He began participating in organized basketball around age seven and soon developed a strong interest in improving his skills.

His father regularly took him and his siblings to local gyms, while his older brother Thomas provided an additional source of competition.

Cormac also spent considerable time playing basketball at the Tony Dapolito Recreation Center in Greenwich Village.

As he grew older, he joined youth basketball programs and traveled throughout New York City for games.

He played on basketball courts in Harlem, Brooklyn and the Bronx, gaining experience against different styles of opponents.

The environment encouraged him to become confident, physically competitive and mentally resilient.

Those qualities eventually became central to his reputation as a college basketball player.

How Cormac Ryan’s Family Supported His High School Career

After beginning his education in New York City, Cormac Ryan moved to Massachusetts to attend Milton Academy.

According to his official University of North Carolina biography, he scored a school-record 1,423 points during his three seasons at Milton.

He was named New England Preparatory School Athletic Council Class A Player of the Year in both 2017 and 2018.

His performances attracted attention from major college basketball programs across the United States.

Although living away from home required adjustments, his family continued supporting his education and athletic development.

Ryan ultimately committed to Stanford University, choosing an institution with a strong academic reputation and competitive NCAA Division I basketball program.

The decision was another important milestone in the family’s sporting tradition.

He began at Stanford University during the 2018–19 season, appearing in 24 games and making 17 starts.

He averaged 8.7 points and 3.5 rebounds per game while becoming one of the team’s leading perimeter shooters.

After his freshman season, Ryan decided to transfer to the University of Notre Dame.

He joined the Fighting Irish program in 2019 but redshirted during the 2019–20 season under the NCAA transfer rules in effect at the time.

Ryan subsequently became an important contributor for Notre Dame and served as a team captain during three consecutive seasons.

He developed a reputation for competitive defense, reliable shooting and leadership.

One of his most memorable Notre Dame performances came during the 2022 NCAA Tournament, when he scored 29 points against Alabama.

His seven three-point field goals established a Notre Dame NCAA Tournament record.

After completing his tenure at Notre Dame, Ryan transferred to the University of North Carolina for the 2023–24 season.

The move allowed him to compete under head coach Hubert Davis while completing additional postgraduate studies.

During his only season with the Tar Heels, he averaged 11.5 points per game and became a key contributor to the team’s Atlantic Coast Conference championship campaign.

His most memorable performance came on March 9, 2024, when he scored 31 points against Duke.

Throughout these experiences, his parents and siblings remained important supporters.

After completing his college basketball career in 2024, Cormac Ryan entered the NBA Draft.

Although he was not selected, he continued pursuing professional basketball opportunities.

He joined the Oklahoma City Thunder for the 2024 NBA Summer League and subsequently signed a training camp contract with the organization.

After being waived before the regular season, he joined the Oklahoma City Blue in the NBA G League.

The opportunity allowed him to gain professional experience while continuing to improve his shooting and overall offensive game.

During the 2024–25 G League season, Ryan appeared in 37 games for Oklahoma City Blue.

He then joined the Milwaukee Bucks organization for the 2025 NBA Summer League.

Although he did not initially earn a regular NBA roster spot, he continued his professional development with the Wisconsin Herd.

According to the Milwaukee Bucks’ official February 26, 2026 announcement, he averaged 20.4 points, 4.6 rebounds, 2.8 assists and 1.5 steals per game through 29 appearances.

He also shot 42.3% from three-point range during that stretch.

His performances demonstrated that the shooting ability he developed in college could translate effectively to professional basketball.

On February 26, 2026, Milwaukee signed Ryan to a two-way NBA contract.

The agreement provided him with an opportunity to play for the Bucks while remaining eligible for development assignments with the Wisconsin Herd.

Ryan subsequently appeared in NBA games for Milwaukee and produced several impressive performances late in the season.

He improved on that achievement on April 10, scoring a career-high 28 points in a victory over the Brooklyn Nets.

His progress from an undrafted college player to an NBA contributor represented an important achievement after years of development across several universities and professional basketball organizations.

How Cormac Ryan’s Family Helped Shape His Competitive Personality

One of the defining features of Cormac Ryan’s basketball career is his competitive mentality.

In his October 2018 interview with Stanford Athletics, Ryan explained that growing up alongside four siblings created constant opportunities for competition.

The children regularly challenged each other during recreational activities and family gatherings.

These experiences helped Ryan become comfortable competing against older and more experienced athletes.

His father’s basketball background also provided an early understanding of the discipline required to succeed.

Meanwhile, his mother encouraged the children to balance athletic ambitions with education and other responsibilities.

The family’s shared experiences at St. Anthony’s gym became particularly important because they combined physical training with time spent together.

Ryan continued demonstrating those values throughout his college career.

At Notre Dame, he served as a team captain for three consecutive seasons, reflecting the trust placed in him by coaches and teammates.

At North Carolina, his competitive personality became one of the team’s defining characteristics during the 2023–24 season.
