Trevor Brolin: The Full Story of Josh Brolin’s Firstborn Son

Trevor Brolin is the firstborn son of actor Josh Brolin. He was born in 1988, when his father was only 20 years old and still at the very start of his own career. That early arrival, Josh has said many times, changed his whole life.

Unlike his famous father and grandfather, Trevor chose not to build a career in front of the camera. He has worked behind the camera on short films, he is a keen artist, and he has built a life in New Mexico in live entertainment. This is his full story, from the public record.

Quick Facts

Born to a Very Young Father

Trevor Mansur Brolin was born on June 26, 1988, in Los Angeles, California. His father, Josh Brolin, was 20, and his mother, Alice Adair, was 22. Josh has been open about how unready he felt. In an interview with The Guardian, he recalled being told he should not be having a child, and he described his younger self, in his own words, as a 19 year old riding a Harley Davidson when the pregnancy happened.

Yet Josh also calls that period his favourite year, because it was the year his whole life changed. He had his first child, and he started doing theatre. In later interviews, and in his memoir and social media posts, Josh returns to the same idea: becoming Trevor’s father was the real start of his adult life.

Trevor’s family roots run deep in acting. His grandfather is James Brolin, known for Marcus Welby, M.D., Hotel, and many film roles, and James later married Barbra Streisand. His grandmother on his father’s side was Jane Cameron Agee, a casting director and wildlife activist from Texas. On paper, Trevor looked set for a life on screen.

His parents’ marriage did not last. Josh and Alice divorced in 1994, when Trevor was about six. His younger sister Eden was born that same period, in 1994, and the two children grew up between two homes, with a father whose career was about to rise sharply in the 2000s.

Growing Up as Josh Brolin Became Famous

For much of Trevor’s childhood, his father was a working actor rather than a star. Josh had early fame in The Goonies in 1985, then years of mixed work. The big turning point came in 2007 and 2008, with No Country for Old Men, W., and Milk, which made Josh one of the most respected actors of his generation. Trevor was already a young adult by then.

That timing matters. Trevor did not grow up inside peak fame. He grew up around sets, theatre, and film people, but also around the normal work and struggle of an actor’s family. People who cover the family note that this may be one reason Trevor and his sister Eden both treat the business in a calm, practical way.

Eden chose acting and built her own career, including a well known role in the series Yellowstone as Mia. Trevor chose a different door into the same wider world: making things, behind the camera and on paper, rather than performing.

Father and son stayed close through the years, at least by every public sign. Josh shares Trevor’s artwork on social media, praises his eye, and even got a tattoo of a rabbit that appears to be based on Trevor’s design. Birthday posts from Josh to Trevor are unusually heartfelt, calling him his firstborn and saying he does not know anybody like him.

Work Behind the Camera

Trevor’s film work is small, real, and fully behind the scenes in spirit. In 2008, he was an additional music composer on X, a short film written and directed by his father, in which his sister Eden also appeared. It was a family project, and a typical first credit for a young person learning the craft from inside.

In 2011 came Felt, a short drama of about six minutes. Trevor wrote, directed, and produced it, and he also worked as its cinematographer and appeared as an actor. Making one short in so many roles is common for young film makers with small budgets, and it shows real interest in the whole process of film making, not just one job.

He also had a brief acting role in the 2011 family short All Kids Count. After that, his public film credits thin out. There is no record of Trevor chasing studio work, series roles, or a public acting career, and any website that lists a long filmography for him is not supported by reliable records.

His steadier work, as reported by People magazine, is at Revel in Albuquerque, New Mexico. Revel is an entertainment venue business offering live music, food, drinks, and game nights. It is entertainment work, but of a local, hands on kind: shows, events, and community nights rather than film sets. Trevor has made Albuquerque his base, far from Los Angeles, and he keeps his social media private.

The Artist His Father Keeps Praising

If one talent of Trevor’s is mentioned again and again, it is his art. Josh Brolin regularly shares images of his son’s artwork with his followers and speaks about it with open pride. The rabbit tattoo Josh wears, linked to Trevor’s drawing, is the clearest public symbol of that respect.

In his June 2022 birthday message, Josh wrote that Trevor has never seen things in a way that has not moved or awed him. In June 2024, for Trevor’s 36th birthday, Josh wrote that Trevor will always be the beginning of what he considers the real start to his life. These are not the words of a distant father. They show a man who sees his son as an original thinker.

Trevor himself does not promote his art in public in a big way. There is no widely known gallery career or public shop attached to his name in reliable sources. His work reaches the public mostly through his father’s posts, which is an unusual and rather touching route for an artist in a famous family.

That modesty fits the whole pattern of his life. He had every family connection needed to chase fame, and he used almost none of them in public. Readers who find that surprising may be measuring success by visibility. By the evidence, Trevor measures it by the work itself and by a private life he controls.

Family Life and a New Chapter

Trevor is the eldest of four Brolin children. After Trevor and Eden, Josh had two daughters with his third wife, Kathryn Boyd, whom he married on September 24, 2016: Westlyn, born in 2018, and Chapel, born in 2020. Josh became a father for the first time at 20 and for the last time at 52, a span he has joked and reflected on often.

Josh has said he was tougher with his older kids and that his younger daughters test him in new ways. The older two, Trevor and Eden, remain a visible part of family photos and tributes, and Josh’s long June 2025 post on fatherhood spoke of how even a passing thought of his four children moves him.

In April 2026, Josh shared happy family news on Instagram: Trevor was engaged to Kristin Wood Hegner. Josh wrote that seeing his son in full adulthood stopped him in his tracks and called the engagement a massive emotional milestone. Reports said the couple live in Albuquerque, keep private social media accounts, and that Wood Hegner works in grant administration for a New Mexico program coalition. Kathryn Boyd Brolin joined the celebration in the comments with heart emojis.

As with most of Trevor’s life, the couple keep the details to themselves. No wedding plans have been made public in reliable sources at the time of writing, and that privacy is fully in keeping with how Trevor has handled every other chapter.

Final Thoughts

Trevor Brolin’s story is not a Hollywood rise, and that is what makes it interesting. Born to a 20 year old father who felt unready, raised in a family full of actors, he quietly built his own path in short films, art, and live entertainment in New Mexico.

His father’s words say the rest. Josh Brolin calls Trevor the real start of his life, praises his unique way of seeing the world, and shares his art with millions. For a firstborn son who never chased the spotlight, that respect, plus an engagement and a life on his own terms, looks like success of a lasting kind.
