The name Marmaduke Mickey Percy Grylls appears in genealogy databases and celebrity-family searches with some regularity. Yet very little independently verified information about him exists beyond his place in a well-known British family. He is not a public figure in his own right, but his full name tends to attract curiosity because of who his father is.
This article covers what is actually known — his family relationship, basic birth details, a profile of his parents, his brothers, and why his name keeps showing up in searches.
Who Marmaduke Mickey Percy Grylls Is
Marmaduke Mickey Percy Grylls is the second son of British adventurer and television presenter Bear Grylls and his wife, Shara Grylls. He is the middle child of three boys, sitting between his older brother Jesse and his younger brother Huckleberry.
He is not a public figure in his own right. His name surfaces mainly because of his father’s global profile, not because he has a documented career or public presence of his own. Sources like People.com and Walker Magazine both identify him as the middle child, though Walker Magazine should be treated as a secondary reference rather than an authoritative record.
The full name — Marmaduke Mickey Percy Grylls — is the version most commonly cited in celebrity-family coverage and genealogy records. Whether this reflects his complete legal name or a variation is not independently confirmed by a primary public record.
His Reported Birth Date and What the Sources Say
Most available sources place his birth in April 2006. Some sources, including Walker Magazine, go further and cite April 6, 2006 as a specific date. However, that level of detail comes from secondary celebrity and biography sites, not from a primary public record such as a civil registration.
People.com supports the general April 2006 timeframe, which is worth noting because People is a reputable entertainment outlet with editorial standards. That said, even reputable entertainment coverage typically relies on information shared by publicists or reported elsewhere, rather than direct access to birth records.
The responsible way to read this is straightforward. April 2006 is the widely reported birth period for Marmaduke. The specific date of April 6 is repeated across several sites but is not confirmed by an independently verified primary source. Readers should treat it as likely rather than officially documented.
Bear Grylls and Shara Grylls — Marmaduke’s Parents
To understand who Marmaduke is, it helps to know a little about his parents. His father is Edward Michael Grylls, known publicly as Bear Grylls. Bear is a former British SAS soldier, author, and television presenter. He became internationally known through survival programming, particularly the series Man vs. Wild, which ran for several years and was broadcast in many countries.
Beyond television, Bear Grylls has built a wide-ranging public career. He has written numerous books, led expeditions, and run youth adventure initiatives. He was born to Conservative politician Sir Michael Grylls and Sarah “Sally” Grylls, née Ford. He also has an older sister named Lara.
Marmaduke’s mother is Shara Cannings Knight. She and Bear Grylls married in 2000. Shara has appeared in some family-oriented media alongside her husband over the years, but she has generally maintained a lower profile than Bear. The couple has consistently kept their children out of the public spotlight, which is one reason so little detailed information about Marmaduke exists in mainstream coverage.
That choice to keep the children private is worth acknowledging. Despite Bear’s sustained international fame, the family has not made their sons a regular part of the public-facing brand. That is a deliberate and reasonable boundary, and responsible reporting should reflect it.
His Brothers — Jesse and Huckleberry Grylls
Marmaduke is the middle of three sons. His older brother is Jesse Grylls, and his younger brother is Huckleberry Grylls. People.com clearly lists all three boys and their birth order, making this one of the better-sourced details available about the family.
All three carry distinctive names. That is consistent with Bear Grylls’ own personality and with a broader British tradition of unusual or heritage-flavored given names. The names Marmaduke, Jesse, and Huckleberry are all memorable, which partly explains why they tend to stick in search results and genealogy databases.
None of the three boys has a confirmed, documented public career at this time. That includes Marmaduke. Readers should not assume that growing up with a survival expert as a father automatically means any of the sons have pursued the same path professionally. There is no reliable sourcing to support that claim for Marmaduke specifically.
Why His Full Name Shows Up in Searches and Family Databases
This is a question worth answering directly, because it is probably why many people end up searching for him in the first place.
Genealogy platforms and celebrity-family databases tend to preserve full legal names, even when mainstream media uses only a first name. So while most entertainment articles simply refer to “Marmaduke” or “Bear Grylls’ son,” family-tree sites may store the complete name: Marmaduke Mickey Percy Grylls. That creates a searchable record that ranks in search results.
Add to that an unusual given name, a globally famous father, and an active celebrity-search culture, and you get a name that generates real search traffic despite very minimal biographical coverage. People are curious, and the full name feels like it ought to have a backstory worth finding.
The honest answer is that the public record on Marmaduke specifically is thin. If you encounter a genealogy listing with his name, treat it as a reference lead rather than a verified document. Genealogy-style pages often aggregate publicly available information without citing original sources or dates clearly. They are useful for orientation, but they are not the same as a civil record or a verified biographical profile.
For readers looking for credible family coverage, World Business Voice and similar outlets that apply editorial standards to celebrity-adjacent topics offer a better benchmark for sourcing than unattributed biography pages.
What Responsible Coverage of a Private Celebrity Child Looks Like
Marmaduke is a private individual. He has not chosen public life, and the fact that his father is famous does not change that. Articles about him should reflect what is actually documented — his family relationship, his approximate birth year, and his place among Bear and Shara’s three sons.
What responsible coverage avoids is just as important. It should not assign him a career, lifestyle, or residence that isn’t supported by reliable sourcing. It should not treat a celebrity blog or genealogy page as equivalent to a verified biographical record. And it should not build out a profile based on what seems plausible given his father’s life.
There is one secondary report, via the British radio station Heart’s website, suggesting that Marmaduke has done some travel in Asia. This detail is worth mentioning only to note that it exists — but it comes from secondary entertainment coverage and should not be expanded into claims about his plans, career, or interests without stronger sourcing behind it.

Final Thoughts
Marmaduke Mickey Percy Grylls is, as far as public information goes, a private young man from a well-known British family. He is Bear and Shara Grylls’ second son, the middle brother to Jesse and Huckleberry, and was reportedly born in April 2006.
Beyond those basics, the public record is limited — and that is worth respecting. His father’s fame is real and well-documented. Marmaduke’s own story, if he ever chooses to share it publicly, is his to tell. Until then, what exists is a name in a database and a place in a family that has, by all accounts, chosen to live largely outside the spotlight.
