Oona Gray Seppala is the eldest daughter of actress Sarah Rafferty and her husband, Santtu Seppälä. Her name is often searched alongside Suits, the legal drama in which Rafferty became widely known for playing Donna Paulsen. Oona, however, is not publicly established as an actress or entertainment personality in her own right. Most dependable information about her comes from interviews in which her mother has discussed family life, filming in Toronto, and raising two daughters while working in television.

A useful biography needs to separate those documented details from assumptions. Oona Gray Seppala’s birth date, parents, younger sister, and some childhood experiences have been reported by established publications. Her current education, occupation, relationships, and private interests have not been confirmed through comparable sources. The aim here is to explain what is known without turning gaps in the public record into a fictional celebrity profile.

Who Is Oona Gray Seppala?

Oona Gray Seppala, also written as Oona Gray Seppälä, is the first daughter of Sarah Rafferty and Santtu Seppälä. Public interest in her largely comes from her mother’s career, especially Rafferty’s portrayal of Donna Paulsen on Suits. The series introduced Rafferty to a broad international audience, and viewers naturally became curious about the actress’s family.

Oona Gray Seppala’s public identity is primarily a family connection rather than a professional one. Established entertainment coverage identifies her as Rafferty’s daughter, but it does not document a film, television, modelling, or influencer career for her. She should not be labelled an actress simply because her mother works in the entertainment industry.

The amount of dependable information about Oona is relatively limited. That is not a reason to fill the gaps with assumptions. It is a reason to be precise about what can be confirmed and careful about details that belong to her private life.

Oona Gray Seppala’s Age and Birthday

Oona Gray Seppala was born on October 22, 2007. She turned 19 on October 22, 2026, so she is 19 years old as of November 6, 2026. PEOPLE’s coverage of Sarah Rafferty’s children confirms the birth date and identifies Oona as the couple’s eldest daughter.

Some older biography pages may still describe her as 18. That figure was accurate before October 22, 2026, but it is no longer current. Including a birth date and a reference date makes age information clearer and prevents an older profile from becoming misleading.

Oona Gray Seppala’s Parents

Oona’s parents have different professional backgrounds. Her mother is an established actress, while her father has worked in finance. Their careers help explain why searches about Oona often focus on both entertainment and family background.

Her mother, Sarah Rafferty

Sarah Rafferty is an American actress best known for playing Donna Paulsen in the legal drama Suits. Donna is a central character whose sharp judgment, confidence, humour, and loyalty made her memorable to viewers. Rafferty appeared throughout the show’s run, and the role remains the main reason many people recognize her.

Rafferty has also appeared in other screen projects, including Netflix’s My Life with the Walter Boys. Although her profession places her in the public eye, she has generally discussed her daughters as part of her family life rather than presenting them as entertainment personalities.

In a 2023 interview with PEOPLE, Rafferty described her children as central to her life. Other interviews show her discussing the practical side of parenting, including work schedules, family travel, and open communication. These comments provide context, but they do not reveal every aspect of Oona’s personal experience.

Her father, Santtu Seppälä

Oona’s father is Santtu Seppälä, whose full name has been reported as Aleksanteri Olli-Pekka Seppälä. He is a finance professional and has maintained a much lower public profile than his wife. A 2023 USA Network profile described him as working in strategy and business development at the Angeleno Group and noted his Finnish family background.

The same profile reported that he and Rafferty met while studying at Yale and married in June 2001. Their marriage began several years before Suits premiered, so their family life was already established before Rafferty’s best-known television role brought wider attention.

Descriptions of Santtu’s career should remain specific. Online profiles sometimes attach detailed job histories or wealth estimates without strong documentation, so a role should not be presented as current unless a reliable source gives a clear date.

Does Oona Gray Seppala Have Any Siblings?

Yes. Oona has one younger sister, Iris Friday Seppälä, who was born on January 27, 2012. Iris is 14 years old as of November 2026. PEOPLE identifies both girls as the daughters of Sarah Rafferty and Santtu Seppälä.

Rafferty has spoken warmly about her daughters together. In a 2014 interview with Parents Canada, she described them as affectionate, funny, and enthusiastic about singing and dancing. In a later interview with Univision, she discussed teaching her daughters empathy, confidence, and the importance of feeling able to speak openly with their parents.

These comments offer a glimpse of the values Rafferty has discussed as a parent. They do not establish detailed facts about the sisters’ personalities or private relationship, which the family has not made a regular subject of media coverage.

Oona Gray Seppala’s Childhood Around the Set of Suits

One of the clearest details about Oona’s childhood is her connection to the production environment of Suits. The show was filmed in Toronto, and Rafferty has explained that her daughters spent time with her there. In interviews, she recalled the girls visiting the set, going to the craft-services area, seeing the hair and makeup trailer, and enjoying costume fittings.

In a 2024 conversation with NewBeauty, Rafferty added that her daughters knew the cast and their families and sometimes called “action” and “cut.” Oona therefore encountered television production from a family perspective, not simply as something she watched on screen.

That experience does not mean Oona appeared in Suits as a credited performer. Visiting a set, meeting cast members, or taking part in a playful behind-the-scenes moment is not the same as having an acting role. No dependable public record establishes her as a cast member or professional performer in the series.

Rafferty has also said that her daughters did not regularly watch Suits, explaining that seeing their mother as Donna could feel strange to them. A performer’s screen identity and a child’s experience of that parent are not necessarily the same.

Growing Up Between Los Angeles and Toronto

During the years when Suits was being made, Rafferty’s work required the family to spend time in both Los Angeles and Toronto. In a 2013 interview with Redbook, she explained that Los Angeles was the family’s home base and that they travelled to Toronto together while the show was filming.

Rafferty also discussed the effect of this arrangement on Oona Gray Seppala’s schooling. At the time, Oona attended school in two cities. Rafferty said she had initially worried about the arrangement, but later felt it had become a positive, confidence-building experience for her daughter.

This is one of the few publicly described details about Oona’s early education. It should not be confused with confirmation of a particular school, later academic record, or university. The interview documents a family routine during a specific period; it does not provide a complete educational history.

The experience illustrates how location-based television work can affect school routines, friendships, and an ordinary week. Rafferty’s comments suggest the family managed those changes together.

Education: What Has Actually Been Confirmed?

There is no sufficiently reliable public account that establishes Oona Gray Seppala’s current school, university, degree, or academic plans. Some online biography pages publish specific school names and extracurricular roles, but those claims should not be repeated as fact unless they can be traced to a trustworthy, independently verifiable source.

The strongest broadly relevant detail is Rafferty’s 2013 account of Oona attending school in both Los Angeles and Toronto while the family moved between the two cities. That provides genuine context about her childhood without implying that her entire education is publicly documented.

A parent’s education should not be confused with a child’s. Rafferty studied at Hamilton College and Yale School of Drama; USA Network has reported that Santtu studied at Yale and earned an MBA from Wharton. None of this establishes Oona’s own academic history.

At 19, Oona may be making decisions about further education, work, or other interests, but no specific path should be assigned to her without confirmation. A responsible profile can acknowledge that the information is not public rather than guessing.

Does Oona Gray Seppala Have an Acting Career?

There is no reliable public evidence establishing Oona as a professional actress. She is connected to the entertainment industry through her mother, and she spent time around the Suits set while growing up. Neither fact proves that she has acted professionally.

Some biography websites call her an actress, singer, dancer, or rising performer without verified credits or a credible interview. Repeating a claim across websites does not make it independently confirmed.

The accurate distinction is straightforward: Sarah Rafferty has a documented acting career; Oona is publicly known as her daughter. If Oona chooses to work in entertainment later, that would be a separate development requiring its own evidence. Until then, it is better not to assign her a profession.

Is Oona Gray Seppala on Social Media?

No public social-media account has been reliably established as Oona’s official profile in the sources reviewed for this article. Images and references to her in entertainment coverage are generally connected with material shared by her mother or with articles about the Rafferty family.

For Oona Gray Seppala, this does not prove that she has no private account or does not use social media. It simply means that an account using a similar name should not automatically be treated as authentic. A verified first-party profile or direct confirmation from Oona would be needed before identifying a particular account as hers.

Celebrity-family searches can lead to impersonation accounts, fan pages, or unrelated profiles. Avoiding unverified usernames protects accuracy and respects personal privacy.

What Is Oona Gray Seppala Doing Now?

As of November 2026, there is no dependable public information establishing Oona’s current occupation, university enrollment, relationship status, or day-to-day activities. Oona Gray Seppala’s most clearly documented public details concern her family and childhood, rather than a present-day public career.

That does not mean she is inactive or lacks ambitions; it means those details have not been reliably reported. A person can have a famous parent without choosing a public life.

For readers researching Oona Gray Seppala, the useful takeaway is to distinguish between a confirmed update and a prediction. Claims that Oona has a particular job, is studying a specific subject, is dating someone, or is preparing to enter the entertainment business should be treated cautiously unless supported by a direct statement or reputable reporting.

Oona Gray Seppala’s Net Worth

Oona Gray Seppala’s personal net worth has not been reliably disclosed. No dependable public financial record or established career earnings provide a basis for assigning her a specific figure.

Some biography sites publish net-worth estimates without a transparent method or evidence. Such figures should not be treated as verified financial information.

Her parents’ careers are separate from her own finances. Sarah Rafferty’s acting work and Santtu Seppälä’s finance career do not establish Oona’s personal assets, income, or net worth. The most accurate answer is that her individual financial position is private and not publicly established.

Why Reliable Information About Her Life Is Limited

The search interest around Oona comes largely from her connection to a recognizable television actor. That creates a common problem with celebrity-family biographies: a small number of confirmed details can be surrounded by pages that add unsupported claims about education, hobbies, career plans, relationships, or wealth.

A detail appearing on several websites is not necessarily verified if those pages repeat one another. Stronger evidence comes from direct interviews, reputable entertainment reporting, official professional records, or statements from the person concerned. In Oona’s case, the most useful sources are interviews in which Sarah Rafferty discusses her daughters and established coverage that confirms basic family details.

The available record supports an account of Oona’s family background and some childhood experiences, but not a complete picture of her private adult life.

Conclusion

Oona Gray Seppala is Sarah Rafferty and Santtu Seppälä’s eldest daughter. Born on October 22, 2007, she is 19 years old as of November 2026 and has a younger sister, Iris Friday Seppälä. Her childhood included time in Los Angeles and Toronto and visits to the Suits set while her mother worked on the series.

Beyond those documented details, much of her current life remains private. There is no reliable basis for assigning her a professional acting career, a confirmed university, a personal net worth, or a verified public social-media identity. The most accurate way to understand Oona is through facts shared by credible sources, while leaving unconfirmed personal details outside the story until they can be verified.
