Early Life and Birth
Oona Gray Seppala was born on October 22, 2007, in Los Angeles, California. She is the first child of Sarah Rafferty and her husband, Santtu Seppälä, whose full name is Aleksanteri Olli-Pekka Seppälä. Her unique first name draws from Una, an Irish name, giving her an identity that stands apart from typical celebrity-family naming trends.
Because Suits filmed in Toronto while the family’s home base remained in Los Angeles, Oona spent part of her childhood moving between two cities. Rafferty has said in past interviews that she initially worried this back-and-forth lifestyle might unsettle her daughter, but it instead became a confidence-building experience that helped Oona adapt easily to new environments.
Family Background
Oona’s parents, Sarah Rafferty and Santtu Seppälä, met while attending Yale University and married on June 23, 2001. Santtu works in financial services as a stock and investment analyst, and his Finnish heritage adds a distinct cultural layer to Oona’s upbringing alongside her mother’s American roots.
The couple welcomed a second daughter, Iris Friday Seppälä, on January 27, 2012, making Oona the older sister by nearly five years. Rafferty has described the two girls as close, noting that empathy and open communication have always been central to how she and Santtu raise their children.
Sarah Rafferty’s Career and Influence
Sarah Rafferty spent nine seasons playing Donna Paulsen on Suits, a role that made her one of the most recognizable faces on American television. She has since appeared in projects including My Life with the Walter Boys, where she has spoken about drawing on her real experience as a mother to play maternal characters.
Despite her career demands, Rafferty has repeatedly emphasized that her daughters come first. In a December 2023 interview with PEOPLE, she said her life revolves around her children at this stage, calling Oona and Iris “perfect.” That sentiment reflects a pattern she has kept throughout her career: sharing warmth toward her kids publicly while still protecting the details of their day-to-day lives.
A Life Kept Largely Private
Unlike many children of celebrities, Oona does not maintain a public social media presence, and she rarely appears in interviews or press coverage. Rafferty has intentionally kept both of her daughters away from heavy media exposure, choosing to share only occasional milestones, such as birthday tributes on Instagram, rather than regular updates.
This approach has given Oona room to grow up with a level of normalcy that is uncommon for a celebrity’s child. It also means that specific details about her education, hobbies, or career interests have not been confirmed through verified sources, and readers should treat unofficial claims about her professional pursuits with caution until Rafferty or Oona herself addresses them publicly.
Relationship With Her Family
Oona holds a close bond with both of her parents. Rafferty has spoken about raising her daughters with an emphasis on emotional intelligence, encouraging them to express their feelings openly rather than suppress them. Santtu, meanwhile, is known for spending weekends with his daughters, including family camping trips, which has helped balance Rafferty’s demanding filming schedule.
As the older sibling, Oona has taken on a naturally supportive role with Iris. Rafferty has described the sisters as playful yet caring toward one another, a dynamic she credits to the family’s consistent focus on kindness and connection at home.
Conclusion
Oona Gray Seppala’s story is less about the spotlight and more about the values that shaped her: privacy, family closeness, and a blend of American and Finnish heritage. While she may carry her mother’s famous last name association, her own path remains something she and her family continue to define on their own terms.
