When people search for Cassia Peaches Johnson, they usually want to know one thing: who is she, beyond the famous surname? She is the daughter of Boris Johnson, the former UK Prime Minister, and she appears to prefer a life well outside the public eye. This article covers what is publicly known about her — her background, education, and literary interests — and places her within the wider Johnson family, including Boris’s other children and his notable ancestry.
Who Is Cassia Peaches Johnson?
Cassia Peaches Johnson is the daughter of Boris Johnson and his second wife, Marina Wheeler. She was born around 1997, which puts her in her mid-twenties at the time of writing. She is the third of four children born to Boris and Marina during their marriage.
Multiple sources describe her as a writer, following a path seen in both her father and her older sister. Beyond that, confirmed public information about her is limited. As one source puts it plainly, “not much else is known” about Cassia beyond her schooling and her interest in writing.
She is not a public figure in her own right. Coverage of her exists mainly because of interest in her father’s family. That context is worth keeping in mind throughout this article.
Cassia’s Education and Early Literary Interest
Cassia attended Highgate School in North London, a fee-paying school. During her time there, she edited the school’s alumni magazine, the Cholmeleian. That editorial role is the clearest early sign of her interest in writing and journalism.
She later attended Trinity College Dublin for her university studies. The combination of a literary-leaning school role and a university degree suggests a genuine interest in that direction, though the specifics of her career are not well documented in public sources.
It is worth noting that writing and editorial work appear across the Johnson family in different forms. Boris Johnson built his early career as a journalist before entering politics, and he has written several books. Cassia’s older sister, Lara Lettice, has also worked as an editor. Cassia’s school editing role fits naturally into that family pattern.
Her Mother, Marina Wheeler, and the Boris–Marina Family
Cassia’s mother is Marina Wheeler, born in 1964. Marina is a British lawyer and writer — a combination that reflects a strong academic and professional background. She is the daughter of the late Charles Wheeler, a respected BBC journalist and broadcaster, which means Cassia comes from a family with deep roots in both the law and the media on her mother’s side.
Boris Johnson and Marina Wheeler were married and had four children together before separating and later divorcing. Cassia’s full siblings are:
- Lara Lettice Johnson — born 1993, writer and editor
- Milo Arthur Johnson — born 1995
- Cassia Peaches Johnson — born around 1997
- Theodore Apollo Johnson — the youngest from the Boris–Marina marriage
The four siblings share a background that combines political prominence, academic achievement, and a family culture that seems to value writing and intellectual life on both sides.
Boris Johnson’s Eight Children and Where Cassia Fits
Boris Johnson is widely reported to have eight children in total across three relationships. Understanding that full picture helps place Cassia within the broader family.
Four children with Marina Wheeler
These are Lara Lettice, Milo Arthur, Cassia Peaches, and Theodore Apollo. Cassia is the third child from this group. This marriage was Boris’s longest, and these four children are among the best-known members of his family.
One daughter with Helen Macintyre
Boris has one daughter named Stephanie, born in 2009, from a relationship with property developer Helen Macintyre. Stephanie is one of Cassia’s half-siblings.
Three children with Carrie Johnson
Boris married Carrie Johnson, his third wife, and they have three children together:
- Wilfred Lawrie Nicholas Johnson — born April 29, 2020
- Romy Iris Charlotte Johnson — born December 2021
- Frank Alfred Odysseus Johnson — born July 5, 2023
Cassia sits as one of the older children in this large family. Her youngest half-sibling, Frank, was born when Cassia was already in her mid-twenties. The age gap between Boris’s oldest and youngest children now spans roughly three decades.
Boris Johnson’s Parents, Siblings, and Family Background
To understand where Cassia comes from on her father’s side, it helps to look at the generation above Boris as well.
Boris Johnson was born on June 19, 1964, in New York City. His father is Stanley Johnson, born in 1940 in Penzance, who worked as a Conservative MEP and is also a writer. His mother is Charlotte Johnson Wahl (née Fawcett), a painter and the daughter of Sir James Fawcett, a prominent barrister and president of the European Commission for Human Rights. That is a significant combination — a politician-writer for a grandfather and a lawyer-human rights figure for a great-grandfather.
Boris has three full siblings: Rachel, Jo, and Leo Johnson. All three have had their own notable careers. Rachel Johnson is a journalist and author, Jo Johnson served as a government minister, and Leo Johnson has worked in sustainability and broadcasting. The family, taken together, has a strong presence in public life across politics, journalism, and the arts.
Boris also has two half-siblings — Julia and Maximilian — from his father Stanley’s later marriage to Jennifer Kidd.
Boris Johnson’s Ancestry — and What Cassia Inherits
One reason genealogy enthusiasts and curious readers look up names like Cassia’s is the remarkable depth of Boris Johnson’s ancestry. That heritage, by extension, forms part of Cassia’s own family history.
On his father’s side, Boris Johnson has documented genealogical connections to King George II, making him a distant descendant of British royalty through an illegitimate line. This connection is not a claim to the throne — it is purely genealogical — but it is notable. It also means Boris is a distant relative of former Prime Minister David Cameron, as both share descent from George II.
Researchers and genealogical programmes have also highlighted Boris Johnson’s links to the Ottoman Empire and a diverse mix of religious and ethnic heritage. His great-grandfather, Ali Kemal, was a prominent Ottoman journalist, which gives the Johnson family a Turkish line that Boris has occasionally referenced in public. Genealogical analysts exploring his full family tree have found connections to German royalty as well, making his ancestry unusually wide-ranging for a British political figure.
Cassia, as Boris’s daughter, is part of this layered heritage — one that includes lawyers, painters, politicians, writers, journalists, and figures from multiple countries and traditions. It is the kind of family tree that rewards careful research rather than quick summaries.

Why So Little Is Known About Cassia
Cassia Peaches Johnson is not a public figure. She has not sought media attention, and responsible coverage of her is limited to basic, non-intrusive facts: her school, her university, and her interest in writing. Sources covering her consistently note the limits of what is publicly available.
This is not unusual. Many children of prominent politicians choose private lives, and the media generally respects that boundary when there is no public role to report on. Cassia appears to be one such person — someone whose name comes up mainly in the context of her father’s family, rather than through any actions or public role of her own.
That makes it important to read coverage of her with that in mind. The facts available are few, and speculation about her personal life, views, or daily circumstances would not be appropriate or fair.
A Quiet Place in a Very Public Family
Cassia Peaches Johnson occupies a quiet position in what is, by any measure, a very public family. Her father is a former Prime Minister. Her grandparents were a politician, a painter, and a human rights lawyer. Her aunts and uncles are journalists and ministers. Her mother is a practicing lawyer and writer.
Against that backdrop, Cassia’s choice of a low-profile life — studying at Highgate School and Trinity College Dublin, editing a school magazine, pursuing writing — reads as a deliberate and considered path. Whether she takes on a more public role in the future remains to be seen. For now, what is known about her is modest but consistent: she is a writer with a strong family background, and she is one of eight children in a family that continues to grow.
That is enough to answer the question most people are asking when they search her name. Who is Cassia Peaches Johnson? She is Boris Johnson’s daughter, Marina Wheeler’s child, and someone who, so far, has chosen to let her own life speak more quietly than her surname might suggest.
