Origin

Meaning and history of Thelmon

The given name Thelmon is an uncommon variant of the name Telemon, which has its origins in Greek mythology. It is believed to be derived from the Greek words "tele," meaning "far away," and "mon," meaning "to remain" or "to abide." This suggests that the name may have originally referred to someone who lived or traveled far away.

In Greek mythology, Telemon was the son of Eurymus and Periboia. He was a prominent figure in the Trojan War, known for his bravery and prowess in battle. Telemon was also the name of one of the sailors who accompanied Jason and the Argonauts on their quest for the Golden Fleece.

The earliest recorded instances of the name Thelmon can be traced back to the medieval period, particularly in Germanic regions of Europe. One notable bearer of this name was Thelmon de Berseles, a Flemish nobleman who lived in the 13th century and served as a knight in the court of the Count of Flanders.

In later centuries, the name Thelmon remained relatively rare but was occasionally used in various parts of Europe. One example is Thelmon Duval, a French Protestant minister who lived in the 17th century and wrote several influential theological works.

Another historical figure with this name was Thelmon Worthington, an American lawyer and politician from the late 18th and early 19th centuries. He served as a member of the United States House of Representatives from Maryland from 1811 to 1815.

In the 19th century, Thelmon Gregg was a prominent American educator and author. He was born in 1818 and served as the president of Kalamazoo College in Michigan from 1859 to 1863.

Finally, a more recent bearer of the name Thelmon was Thelmon Percival Bradshaw, a British businessman and philanthropist who lived from 1892 to 1981. He was a successful industrialist and made significant contributions to various charitable organizations.

Overall, while not a widely popular name, Thelmon has a rich historical background, with roots in Greek mythology and a scattered presence throughout various periods and regions, particularly in Europe and North America.

FAQ

Thelmon: questions and answers

How many people in the U.S. are named Thelmon?

Name Census puts the figure at roughly 1 living Americans. We arrive at this by taking every SSA birth registration for Thelmon 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 342,754,338 US residents.

Is Thelmon a common name?

We classify Thelmon as "Very Rare". It ranks above 3.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 27 babies have been registered with this name.

When was Thelmon most popular?

The single biggest year for Thelmon was 1910, when 6 babies received the name. The fact that the average living Thelmon is about 122 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 Thelmon in that year. That makes it useful for spotting when the name rose, peaked, or faded.

Is Thelmon a male name?

Yes, 100.0% of people registered as Thelmon 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 Thelmon still being used today?

Yes. The SSA still recorded Thelmon 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 Thelmon 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.
