● New research of KS3 history textbooks reveals 81% of content focuses on men, with just 19% focused on the experiences of women

● Highlighting a broader societal impact, over half of the public (57%) admit they are more confident naming male historical figures than female ones

● Ancestry is calling on the nation to balance the history books at home by discovering the missing pages of their own female ancestors

United Kingdom, Wednesday 3rd June 2026 – Ancestry, the global leader in family history, introduces “The Parity Principle,” a new measure for historians and educators to address the long-standing, significant gender bias in recorded history.

This comes as new research from Ancestry reveals the stark reality of the women missing from our histories. Shockingly, a new review of KS3 history textbooks shows that men are mentioned four times (81%) more often than women (19%) . What's more, over half of the public (57%) admit they are more confident naming male historical figures than female ones , and nearly two-thirds (64%) fear that AI, if trained only on traditional historical materials , will fail to address the experiences of the women of our past. Furthermore, nearly two-thirds (64%) of people believe the omission of women’s accomplishments has directly influenced attitudes to modern gender roles .

While Ancestry is urging those who document and record history to place more emphasis on women's roles, they are also encouraging the public to look at the female history closer to home - the women who came before them in their own families. To demonstrate the wealth of stories waiting to be discovered, Ancestry has partnered with Historic England to highlight 25 remarkable women championed through public nominations to the National Blue Plaque scheme. Found within records like the 1921 Census of England and Wales on Ancestry, the lives of unsung female war heroes, pioneering scientists, and the country's first policewomen prove that there is no shortage of inspiring women in our families whose stories are just waiting to be discovered.

The human cost of not showing women's achievements in mainstream recorded history is tangible. Dr Annie Hyatt was one of fewer than 500 female doctors in Edwardian Britain, the first woman appointed Deputy Medical Officer of Health, and a trailblazer who built an entirely self-sufficient professional life outside of marriage. Mary Cartwright, a groundbreaking mathematician laid the vital foundations for chaos theory and the Butterfly Effect, becoming the first female President of the London Mathematical Society. However, both women, alongside 23 others uncovered by Ancestry, remain largely unknown or celebrated.

Ancestry unveils its Missing Pages installation at London's Potters Field Park, a powerful visualisation highlighting new research which reveals women account for just 19% of named historical figures in UK KS3 history textbooks, in contrast to 81% of content which focuses on men’s lived experiences.

For the first time, a formal framework has been created to help address that. Developed by Ancestry and historian Dr. Amy Boyington and inspired by the Bechdel Test for fiction, “The Parity Principle” provides a simple set of criteria for historians, educators, and the public to assess whether historical works offer a complete picture of the past by including the experiences of both men and women. The test arrives at a crucial time for educators, as an overwhelming nearly four in five (79%) teachers surveyed agree that a simple, standardised framework would be helpful to ensure they cover diverse perspectives in their lessons .

Anna Whitehouse, founder of Mother Pukka said “It is astounding that the women who shaped our world are still being relegated to the footnotes of history. I experienced this erasure firsthand when researching my paternal grandmother. Seeing her life reduced to the occupation of ‘wife of’ on her death certificate was a turning point. But finding her census returns and marriage records on Ancestry gave me the tangible evidence I needed to make her story real and sparked entirely new conversations with the women in my family. It is time we unearth the incredible women from our shared history, starting with our own ancestors, to give them the recognition they so rightly deserve, and to show our children the true, equal picture of who shaped the world.”

Ancestry’s partnership with Historic England demonstrates a shared commitment to telling new and unknown stories from women’s history, celebrating pioneers, activists and community leaders who have shaped England’s history. Through the 1921 Census of England and Wales and the National Blue Plaque Scheme, run by Historic England, we’re shining a light on the many untold histories of women of the twentieth century.

Additional data points:

● Four in five of the historical figures named in KS3 history textbooks are men. Women account for only 19% (313) of named mentions compared to 81% (1,333) for men.

● Two-thirds of Britons (66%) are calling for a formal review of the national history curriculum to ensure a more balanced representation.

● Even in modern history sections (1901-Present) of KS3 history textbooks, women’s representation does not improve, still accounting for fewer than one in five mentions.

● 64% warn of an impending “AI Blindspot,” fearing Artificial Intelligence will fail to learn women's stories if trained only on traditional history books.
