Origin
Meaning and history of Amerius
The given name Amerius has its origins in ancient Rome, deriving from the Latin word "amesius," which means "pleasant" or "agreeable." This name came into prominence during the imperial era of Rome, around the 1st century AD.
One of the earliest recorded instances of the name Amerius can be found in the writings of the Roman historian Livy, who mentioned a Roman soldier named Amerius Quintillus who fought bravely during the Punic Wars against Carthage in the 3rd century BC.
In the 2nd century AD, a prominent Roman senator named Amerius Cornelius was known for his oratory skills and his influence in the Roman Senate. He played a crucial role in negotiating peace treaties with neighboring tribes.
During the late Roman Empire, a Christian martyr named Amerius of Trier lived in the 4th century AD. He was persecuted for his faith and eventually executed under the rule of Emperor Diocletian. His martyrdom was recorded in various early Christian texts, and he is venerated as a saint in some Christian traditions.
In the Middle Ages, a notable figure named Amerius of Auxerre lived in the 9th century AD. He was a renowned scholar and theologian who made significant contributions to the field of education and the preservation of ancient texts.
Another prominent individual with the name Amerius was a 13th-century Italian nobleman named Amerius de Prato. He was a wealthy landowner and a patron of the arts, known for commissioning various architectural projects and supporting artists and writers of his time.

FAQ
Amerius: questions and answers
How many people in the U.S. are named Amerius?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Amerius 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 Amerius a common name?
We classify Amerius 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 Amerius most popular?
The single biggest year for Amerius was 2009, when 5 babies received the name. The fact that the average living Amerius is about 12 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 Amerius in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Amerius a female name?
Yes, 50.0% of people registered as Amerius in the SSA data are female. 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 Amerius still being used today?
Yes. The SSA still recorded Amerius 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 Amerius 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.
