Marmaduke Mickey Percy Grylls is the middle son of British adventurer and television personality Bear Grylls and his wife, Shara Grylls. Born on 6 April 2006, he is 20 years old in 2026. Unlike his father, Marmaduke has largely stayed away from the spotlight. Recent public reporting shows a young man who attended Eton College, worked in a London butcher’s shop, travelled independently through Asia and later worked at the 2025 Wimbledon Championships. He is now studying Business and Management at Durham University.
Who Is Marmaduke Mickey Percy Grylls?
Marmaduke Mickey Percy Grylls is best known as Bear Grylls’ second son.
His full name is Marmaduke Mickey Percy Grylls, although he is generally referred to publicly as Marmaduke Grylls. He was born on 6 April 2006 to Edward Michael “Bear” Grylls and Shara Grylls. The Peerage records his birth and parentage, while more recent reporting confirms his place within the Grylls family.
He has two brothers:
- Jesse Grylls, the eldest
- Huckleberry Grylls, the youngest
That makes Marmaduke the middle of Bear and Shara Grylls’ three sons.
This point is worth clarifying because some older biography websites incorrectly describe Marmaduke as the youngest Grylls son.
How Old Is Marmaduke Grylls?
Marmaduke Grylls was born on 6 April 2006.
As of August 2026, he is 20 years old. His birth date has been recorded by The Peerage, with the original information attributed to a 2006 Telegraph notice.
His age is sometimes incorrect on older websites because many online biographies have not been updated since he was a teenager.
Marmaduke Grylls’ Parents and Siblings
His father, Bear Grylls
Bear Grylls is one of Britain’s best-known television adventurers. He became internationally recognised through survival and adventure programmes, including Man vs. Wild and Running Wild with Bear Grylls.
Marmaduke grew up with that unusual family background, but he has not simply followed his father’s career into television.
His mother, Shara Grylls
Marmaduke’s mother is Shara Grylls. She has generally maintained a lower public profile than her husband.
Bear and Shara married in 2000 and have three sons: Jesse, Marmaduke and Huckleberry.
His brothers
Jesse is Marmaduke’s older brother, while Huckleberry is his younger brother.
All three have attracted some public interest because of their father’s career, but each has taken a different direction. Recent reporting describes Jesse as pursuing creative work, while Huckleberry has developed interests including tennis and outdoor activities.
Where Did Marmaduke Grylls Go to School?
Marmaduke attended Eton College, the independent boarding school in Berkshire.
According to recent reporting citing his LinkedIn profile, he graduated from Eton in 2024.
That period marked the transition between his school years and a much more independent stage of his life.
Rather than immediately becoming involved in his father’s television career, Marmaduke spent time working and travelling.
What Did Marmaduke Grylls Do After Eton?
One of the more interesting details about Marmaduke’s early adulthood is that he reportedly worked in a butcher’s shop in London after leaving Eton.
The job became particularly notable because Bear Grylls said his son worked to earn money before travelling through Asia. The Standard reported in 2025 that Marmaduke had been working in a London butcher’s shop before setting off on his trip.
It is a useful detail because it gives a more realistic picture of his life than many celebrity-family profiles.
Marmaduke was born into a wealthy and famous family, but public accounts indicate that he chose to work before funding his own travels.
Did Marmaduke Grylls Travel Around Asia?
Yes.
In February 2025, Bear Grylls shared that Marmaduke was preparing to travel through Asia for around four months.
Bear said his son had worked in a London butcher’s shop, earned his way and was then setting off on his own adventure. The family had been in Australia before Marmaduke continued towards Asia.
The trip attracted attention largely because of its independence. Marmaduke was not travelling as part of a television programme alongside his father; it was presented publicly as his own journey.
There is limited reliable public information about the precise route, places visited or day-to-day experiences, so it would be misleading to fill those gaps with speculation.
Did Marmaduke Grylls Work at Wimbledon?
Yes.
Marmaduke worked at the 2025 Wimbledon Championships as a hot-dog vendor.
The Standard reported that he spent about two weeks working at Wimbledon and that Bear Grylls said he was serving as many as 5,000 hot dogs a day.
That figure should be treated as a reported figure rather than an independently audited sales record.
Still, the Wimbledon job became one of the most widely reported details about Marmaduke because it was so different from what readers might expect from the son of a famous television adventurer.
It also followed his London butcher’s job and Asia trip, adding to the picture of someone gaining practical work experience rather than relying solely on his family’s public profile.
What Is Marmaduke Grylls Studying?
Recent reporting says Marmaduke is studying Business and Management at Durham University.
People’s 2026 profile of Bear Grylls’ children says Marmaduke has been enrolled at Durham since 2025 and is pursuing a BA in Business and Management.
His LinkedIn profile also provides a current public professional identity, although personal profiles can change and should not be treated as a permanent record.
His choice of Business and Management is also a clear departure from assuming that every Grylls child will pursue television, survival or expedition work.
Is Marmaduke Grylls Following Bear Into Adventure?
There is a family connection to adventure, but there is currently no strong evidence that Marmaduke is pursuing Bear Grylls’ television career.
His travel through Asia certainly fits the family’s adventurous background. However, travelling independently is not the same thing as becoming a professional survival expert or television presenter.
His publicly reported path so far is better described as:
Eton College → practical work → independent travel → Wimbledon employment → university.
That is considerably more grounded than some online profiles suggest.
What Is Known About Marmaduke Grylls’ Private Life?
Not very much, and that distinction matters.
Marmaduke is a young adult who is publicly known largely because of his father. Bear Grylls has occasionally shared family photographs and milestone updates, but Marmaduke’s personal life remains comparatively private.
There is no good reason to treat rumours about relationships, private friendships, undisclosed earnings or personal habits as established facts.
Similarly, claims about his exact height, personality, wealth or future career should be approached carefully unless they come from a reliable, attributable source.
For a young person who is not a public figure in his own right, separating confirmed information from speculation produces a much more useful biography.
Marmaduke Grylls’ Name: Why Is It So Unusual?
The full name Marmaduke Mickey Percy Grylls naturally attracts attention.
“Marmaduke” is the name used most often in public, while Mickey and Percy are his middle names.
His brothers also have distinctive names: Jesse and Huckleberry. That has led to considerable online curiosity about the Grylls family’s naming choices.
However, there is little reliable evidence explaining the personal reasoning behind each of Marmaduke’s names. Online articles sometimes provide elaborate meanings or family explanations without clearly establishing their sources.
It is therefore safer to stick to what is documented rather than presenting an attractive but unsupported explanation as fact.
