Her father is John Anstruther-Gough-Calthorpe. Her mother is Lady Mary-Gaye Curzon. Through her mother, Isabella is connected to the Curzon family. Her maternal grandfather was Edward Curzon, 6th Earl Howe. Through her father, she is linked to the Anstruther-Gough-Calthorpe line, another recognised British family.

Her full siblings include Georgiana Calthorpe and Jacobi Anstruther-Gough-Calthorpe. Georgiana is known for her work as an artist.

Isabella Calthorpe Education

Isabella received a strong education before she entered acting. She attended Heathfield School in Ascot, a well-known girls’ school. She later studied at Bradfield College. After school, she went to the University of Edinburgh. There, she studied Classics and Art History. These subjects gave her a deeper interest in culture, history, stories and performance.

Her next major step was drama training. She studied at the London Academy of Music and Dramatic Art, also known as LAMDA, from 2003 to 2005. LAMDA is one of the United Kingdom’s respected drama schools. Her training there helped prepare her for stage and screen work.

Why Her Education Matters

Modelling and Society Life

She attended public events and became part of a social circle that included actors, aristocratic families, business figures and royal friends.

After marriage, she became known as Isabella Branson. Her marriage connected her to one of Britain’s most famous business families.

Sam Branson’s Background

Sam Branson is a filmmaker, musician, entrepreneur and philanthropist. He has been involved in charity work, environmental causes and creative projects. His public image is different from a traditional business heir. He has often focused on purpose, music, film and social impact. This makes Isabella and Sam a couple with strong links to both society and creative life.

Isabella Calthorpe Children

Isabella and Sam Branson have two children. Their daughter is Eva-Deia Branson, born on 19 February 2015. Their son is Bluey Rafe Richard Branson, born on 18 January 2017. Family life has become a major part of Isabella’s story. She has taken a quieter path in recent years, with more focus on home, children and private life. Sam has shared loving family moments over the years, showing a warm bond with Isabella and their children.

There has been interest in the term “Sam Branson split” because of older stories from before their marriage. The couple did spend time apart before they married, but they later reunited and became husband and wife in 2013. There is no confirmed current divorce.

Isabella Calthorpe and Prince William

Isabella Calthorpe has often been linked with Prince William in older media stories. These stories claim that Prince William once had an interest in her before he married Catherine, Princess of Wales. This part of her life should be handled with care. There is no official confirmation that Isabella and Prince William had a serious relationship. The stronger and confirmed fact is that she married Sam Branson in 2013. Her name also became connected to royal circles through her half-sister Cressida Bonas, who dated Prince Harry. Because of these links, Isabella’s name has remained part of royal-related stories for many years.

Best Way to Understand the Royal Link

The Prince William connection is best seen as old media talk, not a proven romance. Isabella’s confirmed life story is based on her family, education, acting career, marriage and children.

Isabella Calthorpe Today

Today, Isabella lives a more private life than she did during her acting years. Her last major screen credits came in the early 2010s. Since then, she has been more focused on family and other personal projects. She has also been connected with podcast work. As Isabella Branson, she has co-hosted Lessons From Our Mothers with her half-sister Cressida Bonas. The podcast focuses on motherhood, family bonds and the lessons people learn from maternal figures. This work fits well with her current life stage. It allows her to speak about family, memory and personal growth in a thoughtful way.

Companies House Record

Companies House records show Isabella Amarylis Anstruther Gough Calthorpe as a former director of FLIP’S FUND. The company number is 04187591. She was appointed on 25 June 2001 and resigned on 30 March 2026. There is a small spelling difference between company records and her full public name. Company records use “Amarylis”, while her full birth name is usually written as “Amaryllis”. For formal company matters, the company record spelling should be used.

Net Worth and Lifestyle

Isabella’s exact net worth has not been confirmed by an official financial source. She has worked as an actress and model, comes from a prominent family, and is married into the Branson family. Still, a clear personal wealth figure is not available. It is better not to give a fixed net worth number without firm proof. Her lifestyle is linked to family heritage, creative work and the Branson family, but her private finances remain private.

Public Image and Personality

Isabella has always had a calm and refined public image. She is not known for scandal or constant publicity. Her reputation is tied to elegance, family life, acting work and strong social connections.

She has built a life that includes acting, motherhood, marriage, charity circles and creative projects.
