Mark Teixeira Children: Jack, Addison and William, Their Mother Leigh and Family Milestones

Mark Teixeira’s November 2026 congressional victory has introduced his family to a new audience beyond baseball. The former World Series champion won election in Texas’s 21st Congressional District, and his campaign biography places his wife Leigh and their three children within that next chapter.

Teixeira’s children are Jack, Addison and William. He and Leigh became parents during the years in which he developed into one of Major League Baseball’s most recognizable first basemen.

The family has occasionally appeared at games, charity events and public milestones. Those appearances provide a record of shared occasions, while the children’s individual adult lives are less extensively documented.

For readers encountering conflicting counts, current campaign material and official baseball records identify three children. Shorter profiles that list only two do not provide the complete family picture.

Who are Mark Teixeira’s three children?

Jack and William are Teixeira’s sons, and Addison is his daughter. Their names appear in his baseball biography and in the current description of his family on the campaign website.

They grew up during a professional career that involved Texas, Atlanta, Southern California and New York. That sequence describes their father’s teams, not a complete account of where each child lived at every stage.

Family photographs at baseball events show them participating in some of his public milestones. They were also part of the farewell period surrounding his retirement from the Yankees in 2016.

Those images are historical records. The ages visible or listed in an older article should not be repeated as though the children remain the same age in 2026.

The reliable sources reviewed do not establish a complete current career biography for each child. Their father’s sports achievements are not evidence that they are following identical professional paths.

Nor does appearing in a campaign family portrait establish a formal campaign role. Family support and paid political work are separate matters that require separate documentation.

A concise factual account can therefore identify the children without filling their lives with assumptions about schools, relationships or professional ambitions.

Who is their mother, Leigh Teixeira?

Leigh, formerly Leigh Williams, met Mark while they were students at Georgia Tech. His baseball biography records that she studied industrial design.

They married in December 2002, before he began his major league career. The relationship consequently predates the championships, awards and long Yankees contract that later made him widely known.

Leigh has generally maintained a quieter public profile, but the couple’s charitable work is documented. They established a fund supporting scholarships and community causes during his playing career.

The family’s public appearances have often been connected with those activities or baseball events. That is different from a continuous public account of their private routines.

There is no verified announcement in the sources reviewed that the marriage has ended. Current campaign material continues to identify Mark and Leigh as a married couple with three children.

The same material describes them as active in their church. That is a stated family connection, rather than a basis for assuming the individual beliefs or political views of each child.

The parents’ shared history at Georgia Tech remains an important part of the family story. It connects their early relationship with a university Mark later returned to in order to finish his degree.

Why did finishing college matter to Teixeira as a father?

Teixeira left Georgia Tech for professional baseball after the Rangers drafted him in 2001. Many years later, he completed the remaining coursework for his business administration degree.

Reporting on his 2022 graduation described the decision partly in terms of setting an example for his children. He was completing something he had started rather than allowing the unfinished degree to remain permanently unresolved.

That is a specific, documented connection between fatherhood and a personal goal. It should not be expanded into claims about what each child studied or how they felt about his decision.

His baseball career had already included a 2009 World Series championship, five Gold Gloves and three All-Star selections. The degree was therefore a different kind of milestone after professional sporting success.

The family later became part of another transition when he ran for Congress. His November 2026 victory over Kristin Hook made him a member-elect for Texas’s 21st Congressional District.

The election brings new responsibilities and scrutiny for Teixeira himself. It does not mean the children have become public officials or that their private lives are necessary to assess his work.

His current family portrait is best understood as one part of a longer timeline: a college relationship, a marriage before his MLB debut, three children and life after retirement.

For readers asking how many children Mark Teixeira has, the answer remains three: Jack, Addison and William. Their mother is Leigh, and the publicly documented family milestones extend from baseball celebrations to his return to college and new political role.

Further details about the children should come from reliable public statements rather than assumptions attached to a famous surname. The confirmed family outline already provides a clear answer without inventing individual biographies.
