Origin
Meaning and history of Tadarious
The name Tadarious is believed to have originated from the ancient Etruscan civilization, which flourished in what is now modern-day Italy between the 8th and 3rd centuries BC. It is thought to be derived from the Etruscan word "tadu," meaning "brave," and the suffix "-rius," which denoted a person's occupation or characteristic.
One of the earliest recorded mentions of the name Tadarious can be found in a fragment of an Etruscan funerary inscription dated to around the 5th century BC. The inscription, discovered near the ancient Etruscan city of Veii, appears to refer to a man named "Tadarius" who was described as a skilled warrior and leader.
During the Roman Republic and Empire, the name Tadarious gained some prominence among the Etruscan-influenced upper classes of Roman society. A notable figure bearing this name was Tadarious Caelius, a Roman senator and military commander who lived in the 1st century AD. He is mentioned in several historical texts, including the writings of the Roman historian Tacitus.
In the Middle Ages, the name Tadarious fell out of common usage but was occasionally recorded among certain noble families in Italy and France. One such individual was Tadarious de Montfort, a French knight who participated in the Seventh Crusade in the 13th century.
The Renaissance period saw a resurgence of interest in classical Etruscan culture, leading to a revival of ancient Etruscan names, including Tadarious. One notable bearer of the name during this time was Tadarious Accolti, an Italian jurist and diplomat who served as a papal legate in the late 15th century.
Over the centuries, the name Tadarious has remained relatively uncommon but has been used sporadically across various cultures and regions. Some other notable individuals with this name include Tadarious Petrucci, an Italian Renaissance painter active in the 16th century, and Tadarious Valmiki, an Indian poet and scholar from the 17th century, best known for his translation of the Hindu epic Ramayana.

FAQ
Tadarious: questions and answers
How many people in the U.S. are named Tadarious?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Tadarious 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 34,275,434 US residents.
Is Tadarious a common name?
We classify Tadarious as "Very Rare". It ranks above 28.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10 babies have been registered with this name.
When was Tadarious most popular?
The single biggest year for Tadarious was 1995, when 5 babies received the name. The fact that the average living Tadarious is about 28 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 Tadarious in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Tadarious a male name?
Yes, 100.0% of people registered as Tadarious 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 Tadarious still being used today?
Yes. The SSA still recorded Tadarious 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 Tadarious 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.
