Dylan Llewellyn: Real Name, Brother’s Tragedy & Derry Girls Role

When you watch Dylan Llewellyn on screen, it’s easy to see only the comedy — the awkward charm of James Maguire in Derry Girls or the sweet sincerity of Jack in Big Boys; but behind the laughs, the English actor carries a personal tragedy that has shaped his life and work: the loss of his brother to suicide. This article separates what is known about Llewellyn’s biography, career, and family from the rumours and gaps that still surround him.

Full Name: Dylan John Llewellyn ·
Date of Birth: 10 September 1992 ·
Place of Birth: Reigate, Surrey, England ·
Occupation: Actor ·
Known For: Derry Girls, Big Boys ·
Notable Loss: Brother died by suicide

Six key facts, one pattern: Llewellyn’s public career is well documented, but his private life — especially the tragedy that shaped him — remains largely unspoken.

The implication: Llewellyn’s biography is sparse beyond the essentials, leaving room for speculation that often goes unchecked.

What is Dylan Llewellyn’s real name?

His full legal name is Dylan John Llewellyn, as recorded by Wikipedia and IMDb (the entertainment database). He was born on 10 September 1992 in Reigate, Surrey, England.

Full legal name

• Dylan John Llewellyn — no middle name variations publicly known.
• He uses “Dylan Llewellyn” professionally; the middle name is omitted in all credits.

Why he uses Dylan Llewellyn professionally

There is no public statement about why he drops the middle name — it’s standard practice for actors to use a shorter stage name. A 2024 profile in The Guardian (UK newspaper) refers to him simply as Dylan Llewellyn throughout.

The implication: his professional name omits the middle name, which is standard practice in the entertainment industry.

Who is the boy in Derry Girls?

Llewellyn played James Maguire, the only male student at Our Lady Immaculate College, in the hit Channel 4 comedy Derry Girls from 2018 to 2022 (British Comedy Guide (UK comedy reference)).

Character James Maguire

• James is an English teenager who moves to Derry and is enrolled in a girls’ school by mistake.
• The character’s naive, earnest nature became a fan favourite.

Dylan’s performance and impact

Reviews praised Llewellyn for bringing vulnerability to a role that could have been a one-note joke. The show ran three seasons and was nominated for multiple BAFTAs. Belfast Live (Northern Irish news outlet) noted that “the wee English fella” became an integral part of the ensemble.

The pattern: Llewellyn’s comedic timing is widely recognised, yet his ability to handle emotional depth is often overlooked.

What happened to Dylan Llewellyn’s brother?

Llewellyn’s brother died by suicide, a tragedy he has spoken about publicly through his work with Cruse Bereavement Support (UK bereavement charity). The exact year of the death is not confirmed in reliable sources; a secondary profile suggests Llewellyn was 16 at the time, which would place it around 2008 (Aussie Briefly (entertainment site) — low confidence).

Details of the loss

• Llewellyn has described the shock and lasting impact of losing a sibling.
• He became an ambassador for Cruse, using his platform to encourage others to seek help.

Dylan’s public grief and charity work

In 2025, he participated in Celebrity Race Across the World alongside his mother Jackie, The Guardian (UK newspaper) reported that the journey was partly a way to process grief together. “It was something we needed to do,” Llewellyn said in the interview.

“I didn’t want to be defined by the tragedy, but I also didn’t want to hide it.”

What this means: the exact date of the loss remains unconfirmed, but his advocacy work provides a clear public record of his grief.

Who is Dylan Llewellyn’s mum?

His mother, Jackie, is a supportive figure who has appeared alongside him in media. She was interviewed with Dylan for a 2025 Guardian feature (UK newspaper), where she discussed his childhood and career.

Mother’s role in his life

• Jackie has been a constant presence, especially after the loss of her son.
• She accompanied Dylan on Celebrity Race Across the World in 2025.

Her appearance in interviews

In the Guardian piece, Jackie described watching Dylan’s early performances and how proud she was of his Derry Girls success. The interview offered rare insight into their family dynamic.

The catch: while Jackie’s first name is known, her surname or any public social media presence is not confirmed.

Does Dylan Llewellyn have special needs?

There is no public record or statement indicating Llewellyn has special needs. The question likely arises from his portrayal of the naive James Maguire in Derry Girls.

No evidence of special needs

• Llewellyn has never disclosed any disability or special needs in interviews.
• He graduated from RADA in 2011, a competitive drama school, which requires a high level of functioning.

Origin of the rumour

Rumours appear to stem from confusion between the actor and his character. A 2025 secondary biography claims he was diagnosed with dyslexia as a child (Celebrity Net Worth UK (entertainment blog) — low confidence), but this is not corroborated by any primary source.

The trade-off: Llewellyn benefits from the visibility of Derry Girls, but the association with a naive character creates a misleading public perception.

Timeline

• 10 September 1992 — Born in Reigate, Surrey (IMDb).
• 2011 — Graduated from RADA; first TV role in Hollyoaks (Wikipedia).
• 2018–2022 — Portrayed James Maguire in Derry Girls (British Comedy Guide).

For anyone who has followed Llewellyn’s career from Derry Girls to Big Boys, the common thread is his ability to blend humour with quiet vulnerability. The tragedy of losing his brother is not just a footnote — it’s the lens through which he now approaches both his art and his advocacy. For fans and mental health advocates alike, the choice is clear: separate the actor from the character, and lend an ear to the real story he’s telling.
