Is Tamsin related to Taron Egerton?

  • Claim: No blood relation between Tamsin Egerton and actor Taron Egerton (Wikipedia biography).
  • Confusion source: Shared surname – both are actors in British productions (Bustle entertainment).
The confusion

The surname Egerton appears twice in British acting circles, but the two are not related. Taron Egerton is Welsh; Tamsin Egerton is English from Hampshire. The mix-up is purely a coincidence of names.

What this means: You can safely dismiss any rumours of a family connection – there is none.

How did Josh Hartnett and Tamsin Egerton meet?

  • Meeting: On the set of The Valley of the Moon (2011) (IMDb profile).
  • Worst movie: Hartnett later called it “the worst movie” he ever starred in (Wikipedia biography).
  • Dating: They began dating around 2012 (Wikipedia biography).

How old was Josh Hartnett when he met his wife?

  • Hartnett was born 21 July 1978 (Wikipedia biography). He was approximately 33 years old when he met Egerton during filming in 2011.
The irony

A film Hartnett disliked so much he publicly called it his worst became the very project that introduced him to his future wife and mother of his four children.

The takeaway: Their meeting was accidental in the truest sense – a job neither likely expected to be life-changing.

How many children does Josh Hartnett have?

Four children, born between roughly 2017 and the early 2020s, according to reports:

  • A fourth child was confirmed in 2024, with no further details public.
The privacy choice

The couple has chosen not to release the names or birth dates of their younger two children, a decision that aligns with their overall commitment to shielding their children from the spotlight.

Why this matters: The steady growth of their family explains why Egerton’s on-screen appearances have become rare.

What is Tamsin Egerton’s ethnicity?

The picture: Her background is firmly English, and though she has lived partly in the US, she remains based in the UK.

  • Primary residence: English countryside (The Independent news).
  • Hartnett moved from the US to the UK to be with Egerton (The Independent news).
  • The couple also spends time in Hartnett’s home state of Minnesota.
The relocation

Hartnett told an interviewer he “never really vibed” with Hollywood, making the move to rural England a natural fit for his temperament.

“It was the worst movie I ever starred in, but it was also the best thing that happened to me because I met my wife.”

— Josh Hartnett, in a 2022 interview (Wikipedia biography)

“The couple are incredibly private about their children and deliberately keep them out of the public eye.”

— A source close to the couple, quoted by Hello! magazine

For the couple, the choice is clear: remain tucked away in the English countryside with their four children, far from the demands of Hollywood. For fans who miss seeing Egerton on screen, the trade-off is an admirable privacy that keeps her family grounded.
