Julie Montagu: Early Life, Husband, Children and Career
The story of an American entrepreneur who became the Countess of Sandwich, built a wellness career, appeared on television, and found a new purpose in British history.
Introduction
Julie Montagu has lived two very different lives. She grew up in a small American town. Today, she is the Countess of Sandwich and helps manage one of England’s historic country estates.
But her story goes beyond an aristocratic title.
She is an entrepreneur, yoga teacher, television presenter, author, and history researcher. Many viewers know her from Ladies of London and An American Aristocrat’s Guide to Great Estates.
Her career has changed considerably over time. She started in the business world, built a name in health and wellness, and later turned her attention to preserving Britain’s historic houses.

Early Life and Family Background
Julie was born on 17 February 1972 and grew up in Sugar Grove, Illinois, a small community outside Chicago.
Her childhood was quite ordinary.
She was the middle child among five siblings. In a 2015 interview, she mentioned attending the same high school as her parents.
Her father is named in genealogical records as Thomas Lee Fisher.
Life in Illinois was very different from the English aristocratic world she later joined. She did not grow up surrounded by historic mansions or inherited titles.
Her American upbringing remains part of her public identity. She often brings that perspective into her television work, especially while visiting historic British homes.
Education and Academic Background
Her education began in the United States.
Biographical profiles report that she studied computer science at Indiana University and was a member of the Delta Delta Delta sorority.
Her early interests were connected to business and technology.
Years later, she returned to formal education with a completely different subject in mind.
She earned a master’s degree in Country House Studies from the University of Buckingham, graduating with Distinction.
Her academic work helped her understand historic buildings, estate collections, archives, and the people who lived in them.
She became particularly interested in American heiresses who married into British aristocratic families during the Gilded Age.
This research eventually became a major part of her professional life.
Early Career and Move to London
Before becoming a television personality, Julie worked in the digital business sector.
She moved to London for work and joined the city’s growing internet industry.
By 2003, she was working at a digital agency.
At the time, she was already raising two children from an earlier marriage.
Then she met Luke Montagu.
It was an unexpected connection. She did not initially realise that Luke belonged to a British aristocratic family.
Their relationship would change her personal life and eventually bring her into the world of historic estates.
Julie Montagu’s Husband and Marriage
Julie is married to Luke Timothy Charles Montagu, the 12th Earl of Sandwich.
The couple met in London in 2003 through mutual friends.
They married on 11 June 2004 at Mapperton, the Montagu family’s estate in Dorset.
At that time, Luke was known as Viscount Hinchingbrooke. Julie became Viscountess Hinchingbrooke after their marriage.
They have spent much of their married life working together on family and estate responsibilities.
Their relationship has also appeared in interviews and programmes about life at Mapperton.
How Many Children Does Julie Montagu Have?
She is a mother of four.
Two children, Emma Fisher and Jack Fisher, are from her earlier marriage.
She has two sons with Luke Montagu: William James Hayman Montagu and Nestor John Sturges Montagu.
William is now styled Viscount Hinchingbrooke following his father’s succession to the earldom.
Julie has spoken publicly about balancing motherhood with her professional responsibilities.
Raising four children while running businesses and helping manage a large estate has been a recurring subject in her interviews.
How Julie Became the Countess of Sandwich
Her aristocratic title changed in February 2025.
Luke’s father, John Montagu, the 11th Earl of Sandwich, died on 1 February 2025.
Luke then succeeded him as the 12th Earl of Sandwich.
Julie became the Countess of Sandwich.
She had previously used the title Viscountess Hinchingbrooke for more than 20 years.
The title comes through her marriage. It does not make her a member of Britain’s royal family.
Although the title attracts attention, her professional work began long before she became a countess.
Business Career and The Flexi Foodie
Julie built a career around yoga, nutrition, and healthy living.
She became known as The Flexi Foodie, a name connected to her food blog and wellness work.
Her interest in nutrition grew while she was raising her family and teaching yoga.
She trained in health coaching through the Institute for Integrative Nutrition and began sharing recipes and food ideas.
Her blog helped her reach readers interested in simple meals and healthier daily habits.
She later developed wellness classes, educational programmes, and related business activities.
Her projects have included yoga teacher training and the Julie Montagu School of Yoga.
She also developed food products under the JUBs! name.
Her business history shows how she moved from working in the digital sector to creating her own projects.
Yoga Teaching and Wellness Work
Yoga became an important part of her working life.
She has spoken about initially finding yoga difficult and later discovering a stronger connection with Vinyasa practice.
She went on to teach classes in London and build programmes for people interested in yoga and nutrition.
Her work also covered stress management, mindful eating, and self-care.
These subjects became the basis of several books.
Over time, her professional focus moved towards history and estate preservation, though wellness remains part of her public interests.
Television Career and Ladies of London
Many people first discovered Julie through Bravo’s reality television series Ladies of London.
The programme followed American and British women living in London’s social circles.
Her appearance introduced viewers to her family life, wellness career, and connection with the British aristocracy.
But television opened another door.
In 2020, she presented the Smithsonian Channel series An American Aristocrat’s Guide to Great Estates.
The programme took viewers inside historic British properties.
She met estate owners, examined historic collections, and learned how families maintain large houses.
The series connected her interest in history with her experience of living at Mapperton.
American Viscountess and American Countess
After her Smithsonian programme ended, Julie continued producing historical content independently.
She launched the American Viscountess project in 2021.
The YouTube series focused on country houses, castles, family archives, and the people responsible for keeping historic properties open.
The name later changed to American Countess after her title changed in 2025.
Through Living History Films, she has worked on documentaries about Britain’s country houses.
These programmes give viewers a closer look at architecture, restoration work, collections, and estate life.
Her projects also use online memberships to support filming and historical preservation.
Julie Montagu’s Books
Writing has been another important part of her career.
Her earlier books focused on food, nutrition, and personal wellbeing.
| Book | Publication Year |
|---|---|
| Superfoods | 2015 |
| Eat Real Food | 2016 |
| Superfoods Superfast | 2016 |
| Recharge: A Year of Self-Care to Focus on You | 2018 |
| Secrets of an English Country House: A Year at Mapperton | 2026 |
Her 2018 book Recharge discusses personal wellbeing through monthly self-care topics.
It covers subjects such as mindful eating, managing stress, and making time for personal needs.
Her latest book takes a different direction.
Secrets of an English Country House: A Year at Mapperton was published on 24 September 2026 by Frances Lincoln, an imprint of Quarto.
The 256-page book follows a year at Mapperton and discusses historic rooms, family collections, gardens, archival discoveries, and estate management.
It reflects the historical work that now occupies much of her time.
Life at Mapperton House
Mapperton House is the historic Montagu family estate in West Dorset, England.
Julie and Luke took over its stewardship in 2016.
The estate covers approximately 1,900 acres, including gardens and surrounding land.
Living there involves far more than occupying a historic building.
Old rooms need repairs. Collections require care. Gardens need constant attention.
There are also financial challenges.
The couple have worked on restoration projects, visitor experiences, filming, and conservation efforts.
They have documented these activities through Mapperton Live and their other media channels.
One area of their work involves rewilding, with parts of the estate managed to support wildlife and natural habitats.
For Julie, the property has become both a home and a major professional responsibility.
Interest in American Heiresses and British History
Her academic research has added another direction to her career.
She studies American women who married into British aristocratic families during the late nineteenth and early twentieth centuries.
One figure she has researched is Alberta Sturges Montagu, the 9th Countess of Sandwich.
Alberta’s letters, diaries, and family history have helped Julie examine the experiences of wealthy American women living in British society.
She shares related historical essays through her Gilded Heiresses publication.
Her research also connects with the documentaries she produces about historic houses.
What Is Julie Montagu Doing in 2026?
As of November 2026, Julie remains active in publishing, filming, and historic preservation.
In March 2026, she announced the Countess of Sandwich Society for the Preservation of Britain’s Living History.
The project supports documentary production and provides members with access to historical films and related material.
September brought the publication of her Mapperton book.
She has also been involved in Stately, a digital membership platform connected to her historic-house projects.
Alongside these activities, she continues sharing estate updates and historical research with her online audience.
Her current career is strongly connected to the preservation and public understanding of Britain’s country houses.
Julie Montagu Net Worth and Income Sources
Her exact net worth is not publicly verified.
She has worked in several commercial fields, including wellness, television, books, and digital media.
Her professional activities may generate income through publishing, speaking engagements, business operations, and membership-supported projects.
However, public information does not establish the total value of her personal assets or earnings.
Mapperton’s land and historic buildings should not automatically be counted as her individual wealth.
Any precise figure without reliable financial evidence would be speculative.
Final Thought
Julie Montagu’s life has changed considerably since her childhood in Illinois.
She worked in business, raised a family, built a wellness career, and became known through television.
Now she spends much of her time researching history and helping care for Mapperton.
Her aristocratic title is certainly part of her story. Still, her career shows a much wider range of interests and responsibilities.
From American entrepreneur to British countess, she has built a public career that continues to change with her interests.
