Siân Phillips Biography: Marriages, Children, and Net Worth

A Welsh girl who grew up speaking only the native tongue of her mining village went on to become one of Britain’s most formidable actresses — and the woman who played the most terrifying Roman empress in television history. Dame Siân Phillips has lived a life that reads like a script: three husbands, a famously turbulent marriage to Peter O’Toole, and a career that stretched from BBC radio dramas at age 11 to Hollywood’s desert planet of Dune.

Born: 14 May 1933 · Birth Name: Dame Jane Elizabeth Ailwên Phillips · Known For: Livia in I, Claudius · Marriages: 3 · Children: 2 daughters · Age at 2025: 91

Seven key facts at a glance — many of them anchored in her own interviews and official records.

The pattern: a career that spanned seven decades while her personal life played out in public view, anchored by a Welsh identity she never shed.

How many husbands did Siân Phillips have?

Siân Phillips has been married three times. Her first marriage, to Don Roy in 1956, lasted barely a year. Then came the actor Peter O’Toole in 1959 — a union that would define much of her public narrative for two decades. Her third marriage was to Robin Butler, a barrister she wed in the mid-1980s, though records differ on the precise year (The Bath Magazine).

Phillips has spoken relatively little about her first marriage in interviews; the Bond and O’Toole chapters dominate her personal history.

Breakdown of Marriages

The catch: a public career that rarely intersected with her private stability once the O’Toole years ended.

Who are Siân Phillips’ children?

She has two daughters: Kate and Patricia O’Toole, both born during her marriage to Peter O’Toole (BBC Wales Arts). The daughters have largely stayed out of the spotlight, though Patricia has been photographed occasionally at events alongside her mother.

The pattern: a private family life, even as the mother’s career played out on public stages.

Does Siân Phillips have grandchildren?

Yes — Phillips has grandchildren. In 2024, a photograph emerged of her granddaughter congratulating Phillips at a London event, confirming the family extends into a third generation (BBC Media Centre). Phillips herself has not detailed names or counts in interviews, keeping that boundary intact.

How long was Peter O’Toole married to Siân Phillips?

Peter O’Toole and Siân Phillips were married from December 1959 until their divorce in 1979 — almost exactly two decades (BBC News). They had two daughters together. The marriage ended in divorce, with Phillips later describing it in a 2024 BBC documentary as “difficult and at times destructive” (BBC Media Centre).

The catch: Twenty years is a long stretch for any partnership, let alone one tested by the extreme pressures of two high-profile acting careers and O’Toole’s legendary drinking.

Was Peter O’Toole a heavy drinker?

O’Toole was known for heavy drinking throughout his adult life, a pattern widely documented by biographers and co-stars. Phillips has acknowledged that his drinking affected their marriage, though she has also balanced those accounts with affection for the man she calls a “genius” (BBC News). The extent of his consumption varies by source, but the broad consensus across interviews and written accounts is that alcohol was a significant factor in the breakdown of their relationship.

Does Siân Phillips live in the Barbican?

Yes. Phillips lives in the Barbican Centre area in London, an iconic residential and cultural complex in the City of London. Social media posts and press interviews confirm her residence there, and she has referenced the Barbican’s quiet courtyards in multiple interviews (BBC Wales Arts).

Siân Phillips movies and TV shows

Phillips’s filmography is long enough to overwhelm a quick list, but two roles anchor her reputation. The first: Livia Drusilla in the 1976 BBC drama I, Claudius — a performance so chilling it still circulates as reaction GIFs half a century later (BBC Wales Arts). The second: Reverend Mother Gaius Helen Mohiam in David Lynch’s 1984 film Dune (BBC News).

Beyond those, she played Emmeline Pankhurst in the BBC drama Shoulder to Shoulder, performed in How Green Was My Valley, and had substantial roles in Tinker, Tailor, Soldier, Spy and Smiley’s People (theartsdesk). Her stage career includes a Tony nomination for playing Marlene Dietrich in Marlene and an Olivier Award for Pal Joey (TheaterMania).

What the interviews reveal

Phillips has given several revealing interviews late in her career. In a 2023 conversation with StageTalk Magazine, she said she likes theatre and screen work equally because both offer “a similar creative buzz.” She told The Bath Magazine that her Welsh-speaking childhood gave her a distinct perspective: she arrived at RADA with a musical ear for English, hearing it almost as a second language. The BBC documentary Siân Phillips at 90, broadcast in September 2024, provided the most comprehensive public account of her life, including her frank assessment of the O’Toole years (BBC Media Centre).

The implication: Phillips defines herself not by any one medium but by the craft itself — a stance that explains her seven-decade career arc.

For anyone following the life of this Welsh star, the picture is remarkably consistent: a woman who started early, married three times, raised two daughters in the shadow of an iconic marriage, and kept working right through her ninth decade. The Barbican flat, the grandchildren’s photos, the enduring reputation as the actress who played Livia — that is the settled view of Siân Phillips, filed and mostly complete. For the viewer who watched her on screen, the question is less about what she did and more about how she endured it all.
