Mark Teixeira’s children have attracted renewed attention following the former New York Yankees star’s victory in the Texas congressional election. The retired baseball player defeated Democrat Kristin Hook to win Texas’s 21st Congressional District, beginning a new chapter in his career. As Teixeira prepares to enter Congress, interest has grown in his family, particularly the three children he shares with his wife, Leigh Williams.
Mark Teixeira has three children: two sons, Jack and William, and a daughter, Addison. He and Leigh have been married since December 2002 and raised their children during his successful Major League Baseball career. Although the former first baseman has occasionally discussed fatherhood, the couple has generally kept their children’s personal lives away from extensive public attention.
How Many Children Does Mark Teixeira Have?
Mark Teixeira has three children with his wife, Leigh Williams Teixeira. Their names are Jack Gordan Teixeira, Addison Leigh Teixeira and William Charles Teixeira.
Jack is the couple’s oldest child, followed by Addison and William.
In a 2017 interview, Teixeira identified their ages as 11, nine and six, respectively. Based on that information, Jack is approximately 20, Addison is around 18, and William is about 16 as of November 2026.
Their exact birthdays have not all been consistently documented in reliable public sources.
The children spent much of their early lives in Greenwich, Connecticut, while their father played for the New York Yankees.
After Teixeira retired from professional baseball, the family gained more opportunities to spend time together without the demands of a full MLB season.
Who Is Mark Teixeira’s Oldest Son Jack?
Jack Gordan Teixeira is Mark and Leigh Teixeira’s oldest child.
He was born around 2005 or 2006, during his father’s years with the Texas Rangers.
Jack grew up watching his father become one of baseball’s leading first basemen.
His childhood included the family’s move to the New York area after Mark signed with the Yankees in December 2008.
In a 2017 interview, Teixeira mentioned that Jack and his sister Addison served as altar servers at their family’s church in Greenwich.
The detail reflected the family’s involvement in religious and community activities.
Although Jack has occasionally been mentioned in interviews, there is limited verified information about his current education, occupation or professional interests.
He has generally remained outside the public spotlight despite his father’s sporting achievements and political career.
Who Is Mark Teixeira’s Daughter Addison?
Addison Leigh Teixeira is the only publicly known daughter of Mark Teixeira and Leigh Williams.
She was born around 2007 or 2008 and grew up alongside her brothers, Jack and William.
Addison spent much of her childhood in Connecticut, where the family lived during Mark’s Yankees career.
Her father previously mentioned that she participated in church activities with her older brother.
The family has emphasized the importance of education, faith and spending time together.
However, Addison has maintained a relatively private life.
There is no widely verified public information establishing her current school, career plans or personal relationships.
Although her father has become increasingly visible through his political activities, Addison has not pursued a prominent public role.
Who Is Mark Teixeira’s Youngest Son William?
William Charles Teixeira is the youngest of Mark and Leigh Teixeira’s three children.
He was born in August 2010, during his father’s second season with the New York Yankees.
His birth became a notable family event during the baseball season.
Teixeira missed two games against the Texas Rangers in August 2010 to be present for William’s arrival.
At the time, Mark was an established member of the Yankees and had recently helped the franchise win the 2009 World Series.
William therefore grew up during the later stages of his father’s professional baseball career.
He was approximately six years old when Teixeira retired after the 2016 season.
As of November 2026, William is 16 years old.
Like his siblings, he has generally remained outside public attention, and his parents have not widely shared details about his everyday activities.
Who Is the Mother of Mark Teixeira’s Children?
The mother of Mark Teixeira’s three children is his wife, Leigh Williams.
Mark and Leigh met while attending the Georgia Institute of Technology in Atlanta.
Leigh studied industrial design, while Mark was developing into a standout college baseball player.
Their relationship began before he entered Major League Baseball.
The couple married on December 7, 2002, several months before Mark made his MLB debut with the Texas Rangers.
They welcomed three children over the following years.
Leigh supported her husband through his time with the Rangers, Atlanta Braves, Los Angeles Angels and New York Yankees.
She also played an important role in family decisions during his professional career.
When Teixeira became a free agent after the 2008 season, Leigh supported his move to New York.
The decision brought the family closer to the East Coast and eventually led to one of the most successful periods of his baseball career.

However, injuries increasingly affected his performance during the final years of his career.
Teixeira experienced wrist problems and other physical setbacks that made it difficult to maintain his previous level of play.
Family considerations also became more important as his children grew older.

The transition gave him greater flexibility to participate in everyday family life.
