Oona Gray Seppälä Quick Bio

Oona Gray Seppälä’s Early Life and Background

Oona Gray Seppälä was born on October 22, 2007, in the United States. Her full name is a mix of English and Finnish roots. She is the first daughter of actress Sarah Rafferty and businessman Santtu Seppälä.

From the very beginning, Oona was surrounded by love. Her family was calm, kind, and full of care. Even though her mom was working in the spotlight, Oona’s early life was kept private. She was raised with values like kindness, confidence, and staying true to herself.

Oona’s home life was filled with warm moments — books, nature walks, cuddles with the family dog, and fun times with her little sister. She was always taught to stay close to her family and know she could talk to them about anything.

A Look at Her Famous Mother, Sarah Rafferty

Oona’s mother, Sarah Rafferty, is a well-known actress who became famous for her role as Donna on the legal drama Suits. She has also appeared in other shows like Grey’s Anatomy, Chicago Med, and My Life With the Walter Boys on Netflix.

But more than being a great actress, Sarah is a loving mom. She has shared in interviews how proud she is to be a mother in real life. In 2023, she told PEOPLE magazine, “My life revolves entirely around my children at this point in my life.”

She’s also said that her daughters are “perfect” and bring her endless joy. Sarah may play moms on TV, but she always reminds people that her role as a real-life mom to Oona and Iris means the most to her.

Oona’s Bond with Her Mom

Oona and her mom Sarah have a very close and open relationship. Sarah has often said she wants her daughters to feel safe and confident. She wants them to know they can always talk to her about anything — no matter what.

In a past interview, when Oona was still young, Sarah said she was teaching her how to be true to herself. She hoped Oona would grow up with a strong sense of family and feel loved no matter where she went in life.

This bond shows in every little story Sarah shares — from helping with school projects to laughing at bedtime. Oona is not just her daughter — she is also her heart.

Oona Gray Seppälä’s Special Relationship with Her Sister Iris

Oona is the big sister to Iris Friday Seppälä, who was born on January 27, 2012. Even though there’s a five-year age gap, the two sisters are super close.

Sarah once said that her daughters love each other deeply. They are silly, fun, and affectionate. One sweet story Sarah shared was how Iris once wrote a note saying, “I’m thankful for my sister because she gives me a napkin when my ice cream drips.” It’s small, but it shows so much love.

The two girls enjoy dancing, singing, dressing up, and playing together. They’ve grown up side by side, sharing hugs, laughs, and simple joys. Oona has always been a caring and loving big sister — and Iris looks up to her every day.

Growing Up Between Two Cities

When Suits was being filmed, Sarah had to spend a lot of time in Toronto, while the family also had a home in Los Angeles. This meant that Oona spent her childhood moving between the two cities.

At first, Sarah was a little worried about how this would affect Oona’s schooling. But in the end, it became a great experience. Oona went to two different schools, made new friends, and learned how to adapt to change — all before her teenage years.

Sarah said this helped Oona build strong self-esteem. She was proud of her ability to adjust and enjoy both places. This kind of upbringing made her open-minded, strong, and flexible — all great qualities for a young girl growing up in a busy world.

Visiting the Suits Set with Mom

One of the fun parts of Oona’s childhood was getting to visit the Suits set with her mom. Both Oona and Iris loved coming to work with Sarah. It was like their own little adventure.

They would go to the craft services truck for snacks, hang out in the hair and makeup trailer, and even dress up in the wardrobe room. Sarah once said those dressing room photos were some of her favorite memories.

Sometimes, the girls would even pretend to be part of the crew — calling “action” and “cut” during scenes. Even though they were just kids, they got to be around creative people and see what their mom did every day. It was both fun and inspiring.

Why Oona Gray Seppälä Stays Out of the Spotlight

Even though her mom is famous, Oona Gray Seppälä has always lived a very private life. Sarah Rafferty and her husband, Santtu Seppälä, made a clear choice to keep their daughters away from the public eye.

Sarah sometimes shares photos of her family on Instagram, but she’s very careful. Oona’s face is often hidden — maybe turned to the side, covered by a hat, or blocked with an emoji. This is done with love, to protect her daughter’s space and peace.

One rare moment where Oona appeared fully in public was in 2018, at Prince Harry and Meghan Markle’s royal wedding in London. It was a special day, and the whole family was there. But apart from that, Oona is rarely seen in the media.

Oona’s Personality: Kind, Funny, and Full of Life

So what is Oona Gray Seppälä like as a person? From what her mom has shared, she sounds like a warm, fun, and loving daughter.

Sarah once said both of her daughters are “so outgoing and funny and silly.” Oona loves to laugh, sing, and dance. She also shows kindness in little ways — like helping her sister when her ice cream melts or being affectionate with family.

Oona also seems to have a calm and gentle heart. Her mom has said she’s proud of how caring and emotionally strong Oona is. She brings light into her family’s life — not by being loud or showy, but by being real, sweet, and thoughtful.

Family Adventures and Travel

Oona’s life may be private, but it’s full of fun and adventure. She and her family love being outdoors and making memories together.

Over the years, Oona has gone on nature walks in Arizona, bike rides in Paris, and canoe trips in Vermont. Her mom often shares small glimpses of these trips, showing just how close the family is.

Oona also shares a special bond with their dog, Rupert. Whether it’s cuddling on the couch or going on walks, Rupert is like another member of the family. These quiet, sweet moments are what make Oona’s life feel full of love.

What We Know About Her School Life

Not much is shared about Oona’s exact school, and that’s on purpose. Her parents have kept those details private to give her a normal life.

But we do know that because of her mom’s filming schedule, Oona went to two different schools — one in Toronto and one in Los Angeles. This could have been confusing, but instead, it made her stronger and more confident.

Sarah said that switching schools actually helped Oona grow. She made new friends, got used to change, and learned how to be brave in new places. That’s a special kind of life lesson not everyone gets.
