Six key facts, one pattern: most of what is publicly known about Sally Thomsett comes from a handful of sources, and several details remain contested or private.
| Fact | Detail | Source |
|---|---|---|
| Full Name | Sally Thomsett | Wikipedia |
| Date of Birth | 3 April 1950 | Wikipedia |
| Place of Birth | Sussex, England | Wikipedia |
| Occupation | Former actress | Wikipedia |
| Years Active | 1969–1990s | TV Guide |
| Notable Work | The Railway Children (1970) | TV Guide |
| Notable Work | Man About the House (1973–1976) | TV Guide |
| Notable Work | Straw Dogs (1971) | IMDb |
| First Marriage | Nigel Newman (1971, divorced 1976) | Wikipedia |
| Second Marriage | Claus Hede Nielsen (1980–1985, separated 1984) | Wikipedia |
| Partner since 1993 | Paul Agnew | Wikipedia |
| Children | One daughter (born 1996) | Wikipedia |
How many times was Sally Thomsett married?
Public records show two marriages, both of which ended. Her first marriage to Nigel Newman began and ended in 1971 per IMDb, though Wikipedia reports they separated later that year and divorced in 1976 (Wikipedia). Her second marriage was to Danish film producer Claus Hede Nielsen from June 1980 to 1985, with separation noted in 1984 (IMDb).
Who was her first husband?
- Nigel Newman — married in 1971, separated soon after (Wikipedia)
- Divorce finalized in 1976 (Wikipedia)
- No other public details about Newman’s identity
Did she have any children?
- She has one daughter with long-term partner Paul Agnew, born in 1996 (Wikipedia)
- A 2019 Mirror report confirmed the couple had been together for over 20 years at that time (Mirror)
- Thomsett reportedly did not marry Agnew because she was still legally married to Claus Hede Nielsen (Mirror)
Thomsett’s private life shows a clear pattern: she valued stability over public visibility. Two marriages that did not work, then a decades-long partnership without a formal ceremony — and she kept the reasons largely to herself.
The implication: Thomsett’s relationship history is less a story of multiple marriages and more a story of one long, quiet partnership with Agnew that never reached the altar.
How old was Sally Thomsett when she was in The Railway Children?
She was born on 3 April 1950 and The Railway Children was released in 1970, making her 20 years old when she played the 11-year-old Phyllis (Smooth Radio). As of 2024, she is 74 years old.
What is her birth date?
- 3 April 1950 (Wikipedia)
- Birthplace: Sussex, England (Wikipedia)
How old is she now?
- Age as of 2024: 74 (born 1950)
- She retired from acting in her 40s (Wikipedia)
Thomsett was a 20-year-old adult playing a pre-teen — and filming rules meant she could not smoke, drink, or drive on set to maintain the illusion (Express). The role that made her famous also required hiding her real age from audiences.
The catch: the same film that launched her career also typecast her. Playing a child at 20 made it harder to transition into adult roles, a challenge many young actors face.
How tall is Sally Thomsett?
Two sources report slightly different numbers. IMDb lists her height as 5 feet 3 inches (1.60 m) (IMDb), while other speculative sources suggest 5 ft 2 in (157 cm). Neither figure is confirmed by official records such as a passport or medical document.
What is her height?
- IMDb: 5 ft 3 in (1.60 m) — confidence: medium (IMDb)
- Other sources: 5 ft 2 in (157 cm) — no official confirmation
Are there any official measurements?
- No government or medical records are publicly available
- All reported heights come from entertainment databases, not primary sources
The pattern: celebrity heights are rarely verified by third parties. For Thomsett, the 1-inch discrepancy is typical of unverified data and does not affect her career legacy.
Did Paula Wilcox and Richard O’Sullivan have a relationship?
Paula Wilcox and Richard O’Sullivan co-starred on Man About the House as the lead characters Chrissy and Robin. Despite on-screen chemistry and persistent rumors, no credible source has confirmed a romantic relationship between them. The rumors remain unsubstantiated (Mirror).
Were they co-stars on Man About the House?
- Both were main cast members from 1973 to 1976
- Thomsett played Jo, the younger sister of Robin’s flatmate
- The show ran for 39 episodes across six series (TVMaze)
Did rumors of a romance affect the show?
- No evidence that behind-the-scenes relationships influenced casting or storylines
- Thomsett’s role was not directly involved in the rumored pairing
Why this matters: celebrity gossip often attaches relationship rumors to any popular on-screen pair. Without confirmation from either actor, these stories do not meet the standard of verified fact.
What is Sally Thomsett doing now?
Thomsett retired from acting in the 1990s and has not taken on any screen roles since (Wikipedia). She lives a private life in Sussex and makes only occasional public appearances, such as cast reunions for The Railway Children or Man About the House (Mirror).
Is she still acting?
- No — last credited role was in the early 1990s (TV Guide)
- No confirmed plans to return to television or film
Where does she live?
- Sussex, England — her home region (Mirror)
- She reportedly returned to Britain after living abroad (Mirror)
Thomsett’s career spanned just over two decades — from her debut in a Children’s Film Foundation production to her last role in the early 1990s (Ciaran Brown). For a child star who started in her teens, the retirement decision was early and definitive.
The pattern: Thomsett’s post-acting life mirrors that of many British actors who chose to leave the industry rather than negotiate its later stage. She has not publicly explained her departure, leaving fans to speculate.

Quotes and perspectives
“I don’t want to be a star. I just want to be an actress.”
— Sally Thomsett, speaking about her career early on (reported by Ciaran Brown)
“Sally was the most professional young actress I ever worked with. She could switch from comedy to drama in a single scene.”
— Richard O’Sullivan, co-star on Man About the House (reported by Mirror)
Thomsett’s own words and those of her peers paint a picture of a performer who valued craft over fame — a choice that eventually led her to walk away entirely.
The consequence for fans of 1970s British television: Sally Thomsett’s legacy is frozen in two iconic roles. There will be no comeback, no interviews explaining her departure, and no public accounting of her private life. For those who remember her as Phyllis or Jo, the story is already complete — and she chose to keep the last chapter unwritten. For British television historians and fans of classic British cinema, the clearest takeaway is this: appreciate the performances as they are, because the performer herself will not be offering context.
