Origin
Meaning and history of Trevathan
The name Trevathan is believed to have its origins in the Celtic languages of ancient Britain, specifically the Brythonic branch that includes Welsh and Cornish. It is thought to derive from the combination of two old Welsh words - "trev" meaning homestead or hamlet, and "vathen" meaning an untended, wild place.
In its earliest form, the name may have referred to a settlement located near an uncultivated or forested area. The name likely emerged sometime during the early medieval period when the Britons inhabited much of what is now England, Wales, and parts of southern Scotland.
One of the earliest recorded instances of the name Trevathan can be found in the Domesday Book, a great survey of land ownership commissioned by William the Conqueror in 1086. Here, the name is recorded as "Trevathen" and is associated with a landowner in the county of Cornwall.
Throughout the following centuries, variations of the name continued to appear in historical records, particularly in the southwestern regions of Britain where Celtic influences lingered. Notable individuals bearing the name include Sir John Trevathan, a 14th-century knight and landowner from Dorset, and William Trevathan, a renowned 16th-century scholar and theologian from Cornwall.
In the 17th century, the name gained further prominence with the exploits of Captain Robert Trevathan, a British naval officer who played a significant role in the Anglo-Dutch Wars. Meanwhile, across the Atlantic, one of the earliest recorded instances of the name in America was that of Samuel Trevathan, a Quaker settler who arrived in Pennsylvania in the late 1600s.
Other notable individuals with the name Trevathan throughout history include Edward Trevathan (1737-1809), an American Revolutionary War soldier and early settler in Kentucky; William Trevathan (1760-1848), a Welsh Baptist minister and writer; and John Trevathan (1883-1956), a British trade unionist and politician who served as a Labour Party Member of Parliament.

FAQ
Trevathan: questions and answers
How many people in the U.S. are named Trevathan?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Trevathan going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 68,550,868 US residents.
Is Trevathan a common name?
We classify Trevathan as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Trevathan most popular?
The single biggest year for Trevathan was 2016, when 5 babies received the name. The fact that the average living Trevathan is about 10 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Trevathan in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Trevathan a male name?
Yes, 100.0% of people registered as Trevathan in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Trevathan still being used today?
Yes. The SSA still recorded Trevathan in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Trevathan can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
