Senan West is the son of Dominic West and Catherine FitzGerald and became the most publicly recognized of their four younger children after making his professional television debut. His breakthrough came with Netflix’s historical drama The Crown, where he portrayed Prince William in Season 5. 

The role attracted particular attention because Senan appeared alongside his real-life father, Dominic West, who played the adult Prince Charles. Their shared casting created a distinctive father-and-son dynamic both on and off screen. Senan’s television debut in 2022 marked an important early milestone in his acting career and established him as one of the younger members of the West family with a visible connection to the entertainment industry.

Net Worth

Dominic West’s financial success has been built primarily through his extensive career in television, film, and theatre. His work in acclaimed productions such as The Wire, The Affair, Downton Abbey, and The Crown has established him as a prominent British actor with an international audience. His earnings and professional achievements are therefore separate from the financial circumstances of his children.

There is no verified public figure for Christabel West’s personal net worth. As a young child without an independent career, business interests, or documented personal income, assigning her a specific monetary value would be speculative. The same caution applies to her younger siblings, whose individual finances have not been publicly established.

Christabel does have a notable family heritage through her mother, Catherine FitzGerald, whose family is historically associated with Glin Castle in County Limerick, Ireland. However, aristocratic ancestry or a connection to a historic estate does not automatically establish personal wealth, inheritance, or property ownership. Those matters should only be stated when supported by reliable evidence.

Christabel West Residency

In 2026, the West family continued to maintain a relatively private lifestyle despite Dominic West’s continuing public career.

The family’s connections include London, the Cotswolds, and Glin Castle in County Limerick. These locations reflect both Dominic’s British career and Catherine FitzGerald’s Irish family heritage.

Christabel West remains the least publicly documented of the five siblings. At approximately nine years old, her life is naturally centered on childhood and family rather than professional achievements.

There are no verified public statements establishing what she hopes to do in the future, and there is no reliable basis for predicting whether she will eventually enter acting, writing, another creative profession, or a completely different field.
