Size Matters: but the male body is more fragile than it looks

A recent study in Biology Letters (2025) confirms that while men are generally taller and heavier, these “sexy and formidable” traits are high-maintenance and come with a hidden biological cost that may impact long-term survival.

The Sensitivity of Stature

Researchers analyzed global data and found that as living conditions improve, men’s gains in height and weight are more than double those of women. In the UK, records from the early 20th century showed men’s heights increasing by 0.69 cm every five years, compared to just 0.25 cm for women.

This suggests that the male body is highly “condition-dependent.” When nutrition is poor or disease is high, male growth is the first thing to be sacrificed. Women, by contrast, are more resilient; their bodies are built to withstand environmental fluctuations without compromising their development as severely.

The Connection to Longevity

This biological resilience likely plays a role in why women consistently live longer than men. The study and its companion research highlight several key factors:

  • Resource Management: Women have smaller frames and less metabolically demanding organs. This makes the female body more “efficient” at surviving on fewer calories and resisting stress.

  • The High Cost of Growth: The same hormones, like testosterone, that drive the development of a “formidable” male body can be taxing on the immune system.

  • Maintenance vs. Muscle: By not investing as heavily in extreme physical size, the female body can divert more energy toward cellular repair and long-term maintenance.

Ultimately, while a taller, heavier frame may have offered advantages in our evolutionary past, it remains a “high-risk, high-reward” strategy. The very traits that make the male body formidable also make it more vulnerable, leaving the more “resilient” female body better equipped for the long haul.

UK Full Text Search Update

On 27 April, FamilySearch added over 6.4 million UK (England) records in four collections to the Full Text Search collection.

United Kingdom, England, Deaths, from 1922 to 1938
United Kingdom, England, Marriages, 1897
United Kingdom, England, Properties, 1961
United Kingdom, England, Religious, from 1792 to 1814

The records are a very mixed bag. I hoped a search of just the updates would be possible. Judging by the types of records returned and their dates, I recommend instead doing a whole corpus search for your term (name) of interest, then filtering down by place and date range.

Ancestry Incorporates the 1926 Irish Census

Ireland, 1926 Census of the Irish Free State

Ancestry has added a new collection featuring an index of 2,972,451 items drawn from the 1926 Census of the Irish Free State. Each entry includes a link to images of the original census pages, hosted on the National Archives of Ireland website.

The census itself comprises two key documents. The Household Form A captures personal details for every individual present in a household on census night, while the House and Building Return Form B provides supplementary information about the size of the dwelling and a more precise home address.

Ireland, Griffith’s Valuation, 1849–1865

Ancestry has also updated its 1,347,783-item index of individuals who occupied property in Ireland between 1849 and 1865.

Interfaith Marriage

Have you ever found an interfaith marriage hidden in your family tree — a union that must have caused raised eyebrows, quiet disapproval, or outright rupture? They are more common than we might expect, even in eras when the barriers seemed insurmountable.

In England and Wales, the Marriage Act 1836 swept away many of the civil law obstacles to interfaith marriage, opening the register office as a neutral alternative to a church ceremony. But the law only went so far. Canon law and communal tradition were another matter entirely, and the social costs of marrying outside one’s faith could be steep.

For Jewish families, the stakes were particularly complex. Jewish identity is matrilineal: a child of a Jewish mother is Jewish regardless of the father’s religion. But the marriage itself remained religiously invalid within the community and was widely stigmatized. A Jewish man who married a non-Jewish woman produced children who were not halachically Jewish — unless the mother converted, a step that required significant commitment and was by no means guaranteed.

The Catholic Church held an equally firm line. In a mixed marriage, the non-Catholic partner was required to promise that any children would be baptized and raised Catholic, and that they would not interfere with their spouse’s faith. These pledges were legally binding in church law — not merely aspirational.

Four cases from my own family tree

Here is how these tensions played out across four interfaith marriages in my English family during the late nineteenth and early twentieth centuries.

Jewish & Catholic

A Jewish man appeared in his children’s baptismal records under a false, non-Jewish first name — presumably to avoid scrutiny or to satisfy the priest. His civil marriage certificate, however, told a different story, recording his Jewish birth name in full. The two records, side by side, reveal a careful act of concealment.

Catholic & Anglican

The husband had been raised Catholic but was non-practising by the time he married. With no pressure to enforce the Catholic Church’s requirements, the path of least resistance prevailed: the children were brought up Anglican, in their mother’s faith.

Anglican & Catholic

Here, the Church’s terms were met squarely. The marriage was solemnized in a Catholic church, and the child was raised Catholic — a straightforward adherence to the promise the Anglican spouse had been required to make.

Jewish & Anglican

In perhaps the most striking case, a Jewish man converted to Anglicanism before marrying the daughter of an Anglican minister. The children were raised in the Church of England. He maintained warm relations with his Jewish parents throughout — suggesting the conversion may have been a pragmatic step rather than a wholesale rejection of his heritage.

Do you have an interfaith marriage in your ancestry? How did your family navigate the pressures of faith, law, and community — and what traces did they leave behind in the records?
