Marmaduke grew up in a home built for challenge. His father, Bear—full name Edward Michael Grylls—hosts shows like Man vs. Wild and served in the British Special Air Service. Shara, his mother, runs a jewelry business and keeps the family grounded. The couple met at university in 1998 and married in 2000.
The Grylls boys—Jesse, Marmaduke, and Huckleberry—faced early tests. Bear took them on hikes in the Alps and survival camps in Wales. Marmaduke, the middle child, learned knot-tying at age 5 and fire-starting by 8. “We raise them tough but kind,” Bear said in a 2020 interview.
Jesse, born in 2003, leads as the eldest at 22. He paints and plays music, with pieces shown in London galleries. Huckleberry, born in 2009 and now 16, matches his dad’s energy—he skydives and scouts. Marmaduke sits between them. At 6 feet 4 inches, he towers over both parents, a trait Bear joked about in a 2024 family photo.
School came at private UK spots like Ludgrove, where Bear studied. Marmaduke focused on science and outdoors. He skipped team sports for solo reads on history. By teens, he eyed trades over desks—practical from day one.
Marmaduke’s name hit screens through family. In 2022, he joined the Queen’s Platinum Jubilee Pageant in London. Crowds saw him wave beside Bear, a quick self-credit on IMDb. No lines, just presence—yet it marked his entry.
Bear’s fame casts a long shadow. With 20 million TV viewers yearly, the family joins cameos on Running Wild. Marmaduke appeared once in 2019, helping build a shelter. Fans noted his calm—unlike Bear’s grit. “He’s the steady one,” Shara told Hello Magazine in 2025.
At 19, fame stays light. No solo deals yet. He links to dad’s brand: Bear’s books sell 10 million copies, and shows earn $5 million per season. Marmaduke aids quietly—testing gear or joining charity runs.
Marmaduke builds his path one skill at a time. Cooking tops his list. In 2023, he enrolled at Vale House Kitchen in Bath, a spot for hands-on meals. He mastered knife work on herbs and slow-roasts on lamb. “Food grounds me after wild days,” he shared in a family post.
That skill paid off. In late 2024, he landed shifts at a London butcher. For six months, he chopped cuts from 6 a.m., saving every pound. By February 2025, he had enough for a big move: four months in Asia. Bear posted a farewell from Australia—Marmaduke boarded with a backpack and grin.
The trip hit Thailand first, then Vietnam. He hiked rice terraces and learned street recipes. Back in April for his 19th birthday, he brought spices home. “Asia taught patience,” Bear captioned a reunion shot. At 184 days from his next birthday, fans track his updates via family shares.
Classes sharpened his edge. Vale House runs small groups—10 students max. Marmaduke prepped 50 meals there, from soups to pies. Now, he eyes a chef path. Family dinners feature his twists: venison with Asian herbs.
Marmaduke’s finances stay simple at 19. Estimates peg his personal net worth at $500,000. This stems from family trusts and small earnings—no big checks yet.
His jobs bring steady cash. The butcher role paid £12 per hour, about $20,000 yearly after taxes. Before that, summer gigs on Bear’s farm added £5,000. No endorsements, but family perks help: free travel on dad’s shoots.
Bear’s wealth sets the base. At $25 million, it flows from TV ($3 million per Running Wild season), books (18 titles, $10 million sales), and talks ($100,000 each). The boys access shares—Marmaduke’s cut could hit $1 million by 25.
Assets include homes. Bear’s portfolio tops $10 million: a Welsh island with lighthouse cottages ($2 million buy in 2010) and a London penthouse ($5 million). Marmaduke visits often, using the island for quiet weekends.
Marmaduke keeps matters private. Single as of 2025, he dates little—focus stays on growth. Friends call him “Marm,” a nod to his full name’s sea link (Old French roots).
Family anchors him. Sundays mean board games or hikes. Bear’s rule: one device-free meal daily. Shara adds calm—her 2024 book on balance sold 50,000 copies. Brothers differ: Jesse creates art, Huckleberry chases thrills. Marmaduke? He listens, then acts.
No drama reports. He skips parties for books—favorites include survival tales like dad’s Mud, Sweat and Tears.
You picture the Grylls home as rugged. Truth: three spots suit all moods. The Welsh island—St Tudwal’s—spans 10 acres with a waterslide into the sea. Bought for $2 million, it hosts family camps: kayaks by day, stars at night. Marmaduke fishes there, grilling catches fresh.
London offers city pulse—a Thames penthouse with views. He crashed there during butcher shifts, walking to work in 20 minutes. A third base? Bear’s houseboat on the Thames—docked for quick escapes.
Hobbies fill gaps. Beyond cooking, he journals travels (three notebooks from Asia) and runs 5Ks weekly. Philanthropy runs deep: the Grylls join Global Angels, a youth charity. In 2024, Marmaduke led a camp for 20 kids—teaching fires and teamwork. Bear’s foundation raised $1 million last year; sons volunteer 50 hours each.
Daily rhythm? Up at 7 for coffee, work or study till noon, afternoons free. Evenings: family calls if apart. At 19, his life balances roots and reach.
Marmaduke’s Aries fire shows in plans—he maps trips with 20-page lists. His name packs history: Marmaduke from old English lords, Mickey a cheeky twist, Percy nods to poets.
He hit 6’4″ by 16, outgrowing Bear at 6’2″. Zodiac fits: Aries charge with Cancer moon depth. Fun tie: Generation Z, born digital but raised offline.
One quirk? He brews tea mid-hike—British to the core.
Marmaduke eyes culinary school next—perhaps Le Cordon Bleu. Or adventure media, blending dad’s world with his calm. At 19, doors open wide. His Asia stint proves it: earn, go, grow.
This son of survival picks steady steps. Watch him—quiet types often lead longest.
