Origin
Meaning and history of Thearthur
The name Thearthur is an ancient one with roots that can be traced back to the Proto-Indo-European language family. Its origins lie in the combination of two words: "thea," meaning "god" or "divine," and "arthur," derived from the word "artha," which signified "noble" or "honorable." This linguistic fusion gave rise to a name that embodied the notion of a divinely blessed and esteemed individual.
The earliest recorded instances of the name Thearthur can be found in ancient Sumerian cuneiform tablets dating back to the 3rd millennium BCE. These clay tablets, unearthed in the region of Mesopotamia, contained lists of personal names, including variations of Thearthur. The name's presence in these ancient records suggests its long-standing cultural significance in the cradle of civilization.
Throughout the millennia, the name Thearthur has appeared in various historical accounts and texts. Notably, it was mentioned in the epic poem "The Iliad" by Homer, where a character bearing this name fought alongside the legendary hero Achilles during the Trojan War. This literary reference, dating back to the 8th century BCE, underscores the name's enduring presence in ancient Greek culture.
One of the earliest recorded individuals bearing the name Thearthur was a prominent Athenian statesman and military leader who lived in the 5th century BCE. Thearthur of Athens played a crucial role in the Peloponnesian War against Sparta, and his strategic wisdom was celebrated by historians of the time.
In the medieval era, the name Thearthur gained prominence in the British Isles. A notable figure was Thearthur of Wessex, a Saxon nobleman who fought alongside King Alfred the Great against the Viking invaders in the 9th century CE.

Another illustrious bearer of the name was Thearthur the Scribe, a renowned 12th-century Irish monk and scholar. His meticulous transcriptions of ancient manuscripts and literary works contributed significantly to the preservation of knowledge during the Middle Ages.

Is Thearthur still being used today?

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 Thearthur 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.
