If you’ve ever watched a movie and thought, Wait, is that a young Meryl Streep?—you aren't seeing things. You're probably just looking at one of her three daughters. It’s kinda wild how much they look like her. But beyond the famous cheekbones and that specific, gentle Roman nose, these women have built actual, sturdy careers without just riding on their mom’s Oscar-winning coattails.
Honestly, being the kid of the "greatest actress of all time" sounds like a nightmare for your ego. How do you even compete with that? You don’t. You just do your own thing.
Meryl and her longtime husband (well, they're separated now, which was a huge shock to everyone in late 2023) Don Gummer, had four kids total. There's Henry, the musician, and then the three sisters: Mamie, Grace, and Louisa. They’ve all gone into the family business—acting—but in very different ways.
Mamie Gummer: The one who looks exactly like Meryl
If you want to know who are Meryl Streep’s daughters, you have to start with Mary Willa "Mamie" Gummer. She’s the oldest. She was born in 1983, right around the time Meryl won her first Best Actress Oscar for Sophie’s Choice.
Mamie is basically her mother’s doppelganger. It’s actually a little spooky. She even played the younger version of Meryl’s character in the 2007 movie Evening. But most people probably recognize her as the wickedly clever, slightly manipulative lawyer Nancy Crozier from The Good Wife and The Good Fight. She played that role for years, and she was so good at being "innocently annoying" that you almost forgot who her mom was.

She’s had a busy few years. She was in True Detective season 3 and headlined her own medical drama, Emily Owens, M.D., back in the day. On the personal side, things have shifted recently. After her first marriage to actor Benjamin Walker ended in 2013, she married writer Mehar Sethi. They have two kids together, but news broke recently in 2025 that they’ve split up. It’s a bummer, but she’s always been super private about her personal life.
Grace Gummer: The indie darling and Broadway pro
Then there’s Grace. She’s the middle daughter, born in 1986. While Mamie feels very much like a "classical" actress, Grace has always had this cooler, slightly more "indie" vibe.
She’s done a ton of TV—Mr. Robot, American Horror Story: Freak Show, and The Newsroom. She’s also a big deal in the theater world. She even won a Theatre World Award for her Broadway debut in Arcadia.
You’ve probably seen her in the news lately because of her husband. She’s married to Mark Ronson, the guy who produced basically every hit song of the last decade (and that massive Barbie soundtrack). They met back in 2019 at a Chanel dinner and got married in 2021. They have a daughter named Ruthie, born in early 2023. Mark is constantly posting about how she’s his "truest love," which is honestly adorable.

Louisa Jacobson: The breakout star of The Gilded Age
The youngest is Louisa. You might notice she doesn't use the last name Gummer professionally. She goes by Louisa Jacobson (Jacobson is her dad’s middle name).
She’s the one currently making the biggest waves on television. She stars as Marian Brook in HBO’s The Gilded Age. It was actually her television debut, which is a massive way to start a career. Before that, she was doing the "normal" route—graduated from Vassar, went to the Yale School of Drama, and did a bunch of stage work.
Louisa made some headlines for her personal life too. During Pride Month in 2024, she officially came out as queer and introduced her partner, Anna Blundell, on Instagram. She’s definitely the one of the three who seems the most comfortable with the modern "social media" era of fame, though she still keeps things relatively low-key compared to most Hollywood stars.
Why they don't talk about their mom constantly
People always ask them about Meryl. It’s inevitable. But if you watch their interviews, they almost never bring her up first. Grace once admitted that being known primarily as "Meryl Streep’s daughter" used to really get to her.

It makes sense. If you’re trying to prove you can act, having the literal GOAT as your mother is a double-edged sword. It gets you in the door, sure, but the expectations are impossible.
They all seem to have this "workhorse" mentality. They don't show up in the tabloids for partying or drama. They just show up, do the play or the TV show, and go home. That's very much the Streep-Gummer way.
Quick Breakdown of the Streep-Gummer Sisters
- Mamie (42): The legal shark Nancy Crozier. Mom of two.
- Grace (39): The theater kid and Mr. Robot hacker. Married to Mark Ronson.
- Louisa (34): The period drama lead in The Gilded Age. Yale Drama grad.
What to watch next if you want to see them in action
If you want to see if the talent really is hereditary, don't just watch their movies where they play Meryl's daughters (though Ricki and the Flash with Mamie is actually pretty good).
Check out The Good Wife for Mamie’s comedic timing. Watch Mr. Robot for Grace’s intensity. And definitely dive into The Gilded Age for Louisa’s leading lady energy. They’ve managed to turn a famous name into a series of actual careers, which is a lot harder than it looks from the outside.
Follow their upcoming projects like the third season of The Gilded Age or Louisa's upcoming film Materialists to see how they continue to distance themselves from the "nepo baby" label through sheer talent.
