The actress, who died on Feb, 26, often spoke about her mother Lana and sister Irene

Michelle Trachtenberg counted her parents and sister as her biggest supporters before her death at age 39.

The actress, who died on Feb. 26, got her start as a Nickelodeon child star in the 1990s before rising to fame with roles in Buffy the Vampire Slayer and Gossip Girl.

In a March 2005 interview with Blackfilm, Michelle shared that although her mom, Lana, was “never a stage mom,” she had “always been there.”

“She is really proud of me, and is really happy that I’m doing something that I love,” the actress said. “She never pushed any of her particular ideals or opinions on me. She always just did what was best and she’s been my inspiring force.”Trachtenberg was found dead in her New York City apartment early in the morning on Feb. 26. Although a cause has yet to be determined, a source told ABC News that Trachtenberg had recently undergone a liver transplant and may have had complications.

Here’s everything to know about Michelle Trachtenberg’s parents, Lana and Michael, and sister, Irene.

They raised her in Brooklyn, then California

Michelle was born in New York, and her family moved to Sheepshead Bay, Brooklyn, where she was raised alongside her sister, Irene.

However, around the age of 12, as her career began to take off, she relocated to Los Angeles while remaining “bicoastal for a little bit,” as she explained in a 2005 radio interview.

Despite adjusting to life in Hollywood, Michelle still cherished parts of her childhood. In the same interview, she recalled how she “loved going to the movies when [she] was little with [her] mom.”

Michelle grew up surrounded by the Russian language, thanks to her mother, who was born in Russia. Meanwhile, her dad is from Germany and once worked as a fiber optics technician, per the New York Post.

In the 2005 radio interview, Michelle shared that she “always heard it around the house,” and it was the only way she could communicate with her grandparents.

When Michelle stepped into the role of Marina Oswald, the wife of John F. Kennedy‘s killer, in 2013’s Killing Kennedy, it required her to speak Russian for most of the film. Although she had a background in the language, Michelle relied on her mother’s help to embody the role.

“Before I’d signed on to it, [the script] was predominantly all in Russian,” Michelle told Fox News in November 2013. “My mom actually was my translator and broke down the entire script for me.”

In a September 2012 interview with Perez Hilton, Trachtenberg said that although her mother didn’t work in the business, she made an impact on those she crossed paths with in the industry.

“Literally to this day, I have people come up to me, like producers that I worked with when I was 8 or 9 years old, and they’re like, ‘How’s your mom?’ because she has such a great reputation,” the Buffy the Vampire Slayer star said. “She’s pretty excellent.”

She and her mom bonded over cooking

In a June 2008 Cosmopolitan blog post, Trachtenberg shared that she and her mother, Lana, bonded over cooking.

“My mom is an amazing cook who always prepared the most delicious meals for me and my sister while we were growing up,” she wrote. “We all know that a home-cooked meal is much more satisfying than a frozen dinner or a quick stop at the drive-thru!”

Michelle revealed that she and Lana had spent years “dreaming” of writing a cookbook filled with quick, healthy recipes families could make together.

As a step toward that goal, Michelle shared one of their favorite dishes — a spinach and feta cheese pasta — as a way to “begin the taste bud celebration.”
