If you’ve spent any time scouring the internet for a photo of Barbra Streisand’s daughter, you’ve probably walked away feeling a little confused. You see the headlines. You see the "rare family photos." Yet, the harder you look for a biological daughter, the more the trail seems to vanish into thin air.
There’s a good reason for that.
Barbra Streisand does not have a biological daughter. She has one biological child, her son Jason Gould, whom she shares with her first husband, Elliott Gould. But because the internet loves a good mystery—and because Barbra’s life has been so incredibly public for over six decades—fans often mistake her talented half-sister or her private stepdaughter for her own child.
The Mystery of Molly Brolin
While Barbra didn't give birth to a daughter, she became a stepmother to one when she married actor James Brolin in 1998. That’s where Molly Brolin enters the picture.
Molly is James’s only daughter from his previous marriage to Jan Smithers. Unlike her famous stepmom or her movie-star brother Josh Brolin (yes, Thanos himself is part of the family tree), Molly is famously low-key. She’s not out there chasing the paparazzi or trying to land a residency in Vegas. Honestly, she seems to prefer the view from behind the scenes.

She has worked in the industry, notably as a production assistant on films like Men in Black 3, but she’s mostly stayed a ghost in the tabloids. Every now and then, Barbra will drop a photo on Instagram that sends the internet into a tailspin. Just recently, in late 2025, Barbra shared a sweet Thanksgiving snap with Molly. They looked genuinely close, huddled together while the grandkids made necklaces in the background. It was one of those rare moments that reminded everyone that "family" isn't just about genetics.
Why People Think Roslyn Kind Is Her Daughter
Another source of confusion? Roslyn Kind.
If you’ve ever seen Roslyn perform, the resemblance is spooky. The voice, the timing, the Brooklyn soul—it’s all there. Because Roslyn is nine years younger than Barbra, people who aren't familiar with the family history often assume she’s Barbra’s daughter.
In reality, Roslyn is Barbra’s half-sister. They share the same mother, Diana Rosen Streisand Kind. Their childhood wasn't exactly a fairytale; Barbra has been very vocal about her strained relationship with her stepfather, Louis Kind, who she felt largely ignored her. When Roslyn was born, Barbra was already a teenager, basically a little woman herself, and she actually helped teach "Rozzie" how to sing and dance.

They’ve performed together many times over the years. Seeing them on stage is like seeing two different versions of the same incredible DNA. But make no mistake: Roslyn is the sister, not the child.
The Only Biological Child: Jason Gould
To really understand Barbra's world, you have to look at Jason Gould. Born in December 1966, he was her "million-dollar baby."
For a long time, Jason lived in the massive shadow of his mother's fame. It couldn't have been easy. Imagine trying to find your own voice when your mom is literally the voice of a generation. He acted alongside her in The Prince of Tides, but eventually, he stepped away from the cameras. He told SFGate years ago that the attention surrounding his mother was a lot to handle. It wasn't about him; it was about the spectacle.
But here’s the cool part: Jason eventually embraced his own musical talent. He has a voice that is soulful, controlled, and surprisingly different from Barbra’s belt-it-to-the-rafters style. When they finally sang "How Deep is the Ocean" together on tour, it wasn't just a gimmick. It was a legitimate musical moment.

The Grandma Era
Even though she never had a biological daughter, Barbra is currently living her best life as a grandmother. Through her stepson Josh Brolin, she has four grandchildren: Trevor, Eden, Westlyn, and Chapel.
She’s the kind of grandma who posts blurry photos of her grandkids on Instagram because she’s too busy being "Grandma" to worry about the lighting. She once shared that one of Westlyn’s first words was "hat"—a funny little coincidence since that’s also a word famously associated with her son Jason's early years.
The Blended Reality
So, if you’re looking for "Barbra Streisand’s daughter," you’re looking for a woman named Molly Brolin, who is her stepdaughter, or you might be thinking of her sister, Roslyn Kind.
Family is complicated. Especially in Hollywood.
Barbra’s family tree is a mix of biological ties, step-relations, and long-standing professional bonds. She’s built a life that includes:
- Jason Gould: Her biological son and musical collaborator.
- Molly Brolin: Her private stepdaughter who she clearly adores.
- Josh and Jess Brolin: Her stepsons from her long marriage to James.
- Roslyn Kind: The younger sister who followed in her footsteps.
What you should do next:
If you're interested in the Streisand legacy, don't just look at the family tree. Go listen to Jason Gould's album Dangerous Man or catch a clip of Roslyn Kind performing "The Shape of Things." Seeing how the talent has manifested in the people closest to Barbra gives you a much better "insider" view than any tabloid headline ever could. It’s not about the biological label; it’s about the art they’ve all created in each other's orbits.
