Four working adults, two of them publishing under names that are not Gummer, and seven credits released between them since June 2025

Meryl Streep’s 4 Children: Henry Wolfe, Mamie, Grace and Louisa

Birth order runs Henry Wolfe Gummer on 13 November 1979, Mary Willa Gummer, known since childhood as Mamie, on 3 August 1983, Grace Gummer on 9 May 1986 and Louisa Jacobson Gummer on 12 June 1991. The first three were born in New York City and the youngest in Los Angeles. All four are the children of Streep and Don Gummer, who married on 30 September 1978.

The household sentence is the part that has gone stale. Streep and Gummer separated in 2017 and confirmed it publicly through a representative in October 2023. They have not divorced. Any profile that describes the marriage in the present tense is writing about an arrangement that ended nine years ago, and getting the ages of the children wrong at the same time.

Every one of the four is a working adult with a public professional record, so this guide is assembled from credits that carry a release date: an HBO season, an A24 feature, a streaming premiere, a record. Their own six children appear here only as a count and a set of years, which is the whole of what their parents have chosen to make public.

Meryl Streep’s four children at a glance

Eleven and a half years separate the eldest from the youngest, which is why the four almost never appear in the same career bracket at the same time. Henry was 11 when Louisa was born and had left for university before she finished primary school. Louisa was leading an HBO period drama in the same months her brother was raising a toddler and a newborn.

The ages carry a date because they expire. Mamie turned 43 on 3 August 2026, seventeen days before this check. Grace turned 40 on 9 May and Louisa 35 on 12 June. Henry turns 47 on 13 November. Older guides hard-coded the numbers 45, 41, 38 and 33 with no date attached, and every one of those was already wrong when it was published.

Why searching Gummer only finds half the family

Type the family surname into any database and two of the four are missing. That is not privacy and it is not estrangement. It is a set of separate professional decisions, one of them forced by a written union rule and two of them made on behalf of children who were seven and 20 months old at the time.

Louisa’s case is the cleanest, because the rule is written down. The Screen Actors Guild requires that no member use a professional name which is the same as, or resembles so closely as to tend to be confused with, the name of any other member. A Louisa Gummer was already on the register, so the youngest of the four went to work under her own middle name.

The two childhood pseudonyms came from the opposite instinct: keeping a famous mother out of the frame while her children were too young to consent to the association. Mamie played Streep’s daughter in Heartburn in 1986, billed as Natalie Stern. Grace played the younger version of Streep’s character in The House of the Spirits in 1993, billed as Jane Grey. Both credits were only connected back to the family years later.

Siblings in one trade have to solve this problem somehow, and the alternative is visible in the two sons John Lennon left behind, who both kept the surname and then spent decades being measured against their father rather than against each other.

Henry Wolfe: the eldest, and the one who left the family trade

Henry Wolfe Gummer was born in New York City on 13 November 1979 and is 46, turning 47 in November. He is the only one of the four who does not act for a living, and he decided that early. Speaking to the New York Daily News, he put it as a question of daily practice rather than ambition: music was something he could work at whenever he wanted, and finishing a song gave him a satisfaction that finishing a role never did.

His education is the one detail on this page where good sources disagree. Reference records give him a Dartmouth College degree completed in 2002. Interviews and profiles describe two years studying acting at New York University’s Tisch School of the Arts before he changed direction. Both can be true of the same person, and the useful part is undisputed: he trained as an actor first and stopped.

The recorded output starts in 2004 with the July EP under the band name Bravo Silva, followed by the album Bravo Silva in 2005. Under his own working name came The Blue House and Wolf Sings Field in 2009, the album Linda Vista in 2011, Enccion in 2014 and Asilomar in 2015. He has also acted twice for the director M Blash, in Lying in 2006 and The Wait in 2011.

He married Tamryn Storm Hawker in June 2019, and they have two children, a daughter born in July 2020 and a son born in May 2022. His most recent dated release on the public record is the 2015 album, so the accurate description of Henry in August 2026 is a musician with a completed catalogue and a young family, rather than an artist with a current release.

Mamie Gummer: forty years of credits, starting at 20 months old

Mary Willa Gummer was born in New York City on 3 August 1983 and has been credited on screen since 1986, when she played Streep’s baby daughter Annie in Mike Nichols’s Heartburn at 20 months old under the name Natalie Stern. She studied theatre at Northwestern University and graduated in 2005, then went to work immediately.

Her professional stage debut came that same year in Mr. Marmalade off Broadway, and it won her a Theatre World Award. Two years later she played the young version of her mother’s character in Evening, which remains the clearest case of a casting director using the family resemblance as a plot device rather than as a novelty.

Television gave her the longest runs. She played the lawyer Nancy Crozier across five years of The Good Wife from 2010, carried her own CBS series Emily Owens, M.D. through 2012 and 2013, appeared opposite her mother again in Ricki and the Flash in 2015 and joined the third season of True Detective in 2019. She voiced Electra across five years of Netflix’s Blood of Zeus.

Her current credit is the one most profiles have missed. Mamie plays Carrie Sinclair, the eldest Sinclair sister, in We Were Liars, the eight-part adaptation released by Prime Video on 18 June 2025 and renewed for a second season that September. A renewal is a commissioned order rather than a delivered episode, so the honest wording is one released season and a second in production.

She married the actor Benjamin Walker in July 2011 and they divorced in March 2013. She married Mehar Sethi in February 2019 and that marriage ended in February 2025. They have two children, born in 2019 and 2021, whom neither parent has put on a public platform.

Grace Gummer: three releases in five months, and a Kennedy

Grace Gummer was born in New York City on 9 May 1986 and turned 40 in May. Her first credit came at seven, playing the younger version of her mother’s character in The House of the Spirits in 1993 under the name Jane Grey. She then left the business alone for fifteen years, taking a Vassar College degree in art history and Italian in 2008 before starting again from the stage.

The run that made her name was television. She appeared in The Newsroom across 2013 and 2014, joined American Horror Story: Freak Show in 2014, and played the FBI agent Dominique DiPierro through three seasons of Mr. Robot from 2016 to 2019. Dr. Death followed in 2021 and American Horror Story: Delicate in 2024.

Then came the densest stretch of her career. She played Barbara Landau in Springsteen: Deliver Me from Nowhere, released by 20th Century Studios on 24 October 2025. She appeared as Grace Henry in Ryan Murphy’s All’s Fair, which premiered on Hulu on 4 November 2025. And on 12 February 2026 she began a nine-episode run as Caroline Kennedy in FX’s Love Story: John F. Kennedy Jr. & Carolyn Bessette.

Three dated credits inside five months is the strongest current working record in the family, and it is exactly the stretch that undated profiles describing her as semi-retired have missed. She married the producer Mark Ronson on 4 September 2021, after a brief 2019 marriage to Tay Strathairn that ended the following year, and they have two daughters, born in December 2022 and on 21 February 2025.

Louisa Jacobson: a Yale MFA, then the biggest current show in the family

Louisa Jacobson Gummer was born in Los Angeles on 12 June 1991 and is 35. She took the longest run-up of the four. She read psychology at Vassar College, graduating in 2013, studied at the British American Drama Academy in Oxford, and only then took a Master of Fine Arts in acting at the Yale School of Drama.

The stage came first and has never stopped. She played Mary Dalton in Native Son in 2017, Janice in The Member of the Wedding at Williamstown in 2018 and Juliet in Romeo and Juliet in 2019. Later came Trayf in 2022, Lunch Bunch in 2023 and Trophy Boys in 2025, in which she plays a teenage boy on a debate team.

Her screen career is essentially one enormous part. She has played Marian Brook in HBO’s The Gilded Age since the series premiered on 24 January 2022. The second season ran from 29 October to 17 December 2023 and the third from 22 June to 10 August 2025. HBO renewed the show for a fourth season on 28 July 2025, and no premiere date for it has been announced.

Away from the series she played Charlotte, one of the matchmaker’s clients, in Celine Song’s Materialists, released by A24 on 13 June 2025. In 2024 she also worked behind the table, as assistant director on the off-Broadway play Invasive Species, and spoke publicly for the first time that June about being a lesbian, in her own words and on her own timing.

Meryl Streep and Don Gummer, and what actually changed in 2023

Streep was born in Summit, New Jersey on 22 June 1949 and is 77. Gummer, an American sculptor whose work sits in permanent collections including the Massachusetts Museum of Contemporary Art, was born on 12 December 1946 and is 79. They married on 30 September 1978 and had four children in twelve years.

They separated in 2017. Nobody announced it at the time, and it only became public in October 2023 when a representative confirmed to reporters that the couple had been living separate lives for six years. There has been no divorce filing on the public record since, which means the accurate description in August 2026 is long separated and still legally married.

Streep’s own recent work matters here because it keeps putting the family name back in front of an audience. She has played the actress Loretta Durkin in Only Murders in the Building since its third season in 2023, returning for the fifth season that ran from 9 September to 28 October 2025. On 1 May 2026 she reprised Miranda Priestly in The Devil Wears Prada 2 for 20th Century Studios, a film that has taken more than 690 million dollars worldwide since release.

There are six grandchildren, two each from Henry, Mamie and Grace. This guide publishes the count and the dates their parents announced themselves, and nothing beyond that, which is the same boundary KidsCo applies to every acting family it covers, including the six adult children of Angelina Jolie. It is the same reason Geena Davis’s three adult children get three sections of very different lengths: one has a study record, one a fraternity board seat, and the third almost nothing anyone is entitled to publish.

Record or report: what each of the four is verifiably doing

A family this well covered attracts a lot of confident writing built on nothing. The filter that works is simple: a release date, a season run, a distributor or a credited episode count is a record. A red-carpet photograph, an anonymous source and a decade-old interview are not. Here is the family through that filter.

Two rows there are doing the careful work. Henry’s stops at 2015 rather than implying a current release schedule, because no later record exists in the sources used here. Louisa’s separates a renewal from a broadcast, which is the difference between a guide that survives the next twelve months and one that gets corrected by a press release.

What most Meryl Streep children pages still get wrong

One habit is worth naming separately: writing about the four as a single unit called the Gummer children. They work in three different industries under three different billing conventions, and one of them has been credited under three separate names across her career. Treating them as one block is how a page ends up attributing an HBO series to the wrong sister.

Screen dynasties collect the same shortcuts everywhere. The Bryce Dallas Howard family guide covers the same question one generation further on, and the KidsCo celebrity family index applies the same dated-evidence rule to every profile in it.

The family timeline and what each date establishes

Two of those dates do more work than the rest. The 1986 Heartburn credit set the family’s pattern of working under other names, which is still the main reason readers cannot find all four in one search. The October 2023 confirmation reset every household sentence written about them for the previous six years, and a great many pages have still not been updated to match.

Questions people ask about Meryl Streep’s four children

How many children does Meryl Streep have?

Meryl Streep has four children with the sculptor Don Gummer: Henry Wolfe, Mamie, Grace and Louisa. On 20 August 2026 they are 46, 43, 40 and 35, and all four work in the arts.

What are the birth dates and ages of Meryl Streep’s children?

Henry was born on 13 November 1979, Mamie on 3 August 1983, Grace on 9 May 1986 and Louisa on 12 June 1991. That makes them 46, 43, 40 and 35 on 20 August 2026.

Who is the father of Meryl Streep’s children?

All four have the same father, the American sculptor Don Gummer, who married Streep on 30 September 1978. The couple separated in 2017 and confirmed the separation publicly in October 2023 without divorcing.

Why does Louisa Jacobson not use the surname Gummer?

Jacobson is her own middle name. Screen Actors Guild rules stop a member using a professional name that closely resembles another member’s, and a Louisa Gummer was already registered, so she works as Louisa Jacobson.

Are all of Meryl Streep’s children actors?

Three of the four are. Mamie, Grace and Louisa all act on screen and on stage. Henry is a musician and songwriter who records as Henry Wolfe and has released work with and without a band since 2004.

Does Meryl Streep have grandchildren?

Yes, six. Henry has two children born in 2020 and 2022, Mamie has two born in 2019 and 2021, and Grace has two daughters born in December 2022 and February 2025. Louisa has no children on the public record.
