Origin
Meaning and history of Theldon
The name Theldon has its origins in the Old English language, tracing back to the Anglo-Saxon period of Britain, around the 5th to 11th centuries AD. It is believed to be derived from a combination of the Old English elements "thel" meaning "plank" or "board," and "dun" meaning "hill" or "down." Together, the name could be interpreted to mean "one who resides on the plank hill" or "one from the hill of planks."
The earliest recorded use of the name Theldon can be found in the Domesday Book, a manuscript record of the Great Survey of England commissioned by William the Conqueror in 1086. It lists several individuals bearing the name, indicating that it was already in use among the Anglo-Saxon population at that time.
One notable historical figure with the name Theldon was a monk who lived in the 12th century. He was a scribe at the Benedictine abbey of St. Albans in Hertfordshire, England, and is credited with transcribing several important manuscripts, including a copy of the Venerable Bede's "Ecclesiastical History of the English People."
Another Theldon of note was a minor landowner and vassal who lived in the late 13th century. He is mentioned in the Pipe Rolls, a series of financial records kept by the Exchequer of England, as having paid taxes on his holdings in the county of Oxfordshire.
In the 14th century, a Theldon was recorded as serving as a member of the Worshipful Company of Weavers, one of the ancient livery companies of the City of London. This suggests that the name was associated with the textile trade during this period.
During the 16th century, a Theldon Browne is documented as having been a member of the Honourable Artillery Company, an elite military unit formed in 1537 to defend the City of London. This Theldon Browne, born around 1520, would have been a contemporary of notable figures such as Henry VIII and William Shakespeare.
While the name Theldon was primarily used in England during the Middle Ages and Renaissance periods, there are also records of individuals bearing this name in other parts of the British Isles, such as Scotland and Wales, indicating that it may have had some regional variations or adoptions.

FAQ
Theldon: questions and answers
How many people in the U.S. are named Theldon?
Name Census puts the figure at roughly 2 living Americans. We arrive at this by taking every SSA birth registration for Theldon 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 171,377,169 US residents.
Is Theldon a common name?
We classify Theldon as "Very Rare". It ranks above 4.3% 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 Theldon most popular?
The single biggest year for Theldon was 1938, when 5 babies received the name. The fact that the average living Theldon is about 71 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 Theldon in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Theldon a male name?
Yes, 100.0% of people registered as Theldon 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 Theldon still being used today?
Yes. The SSA still recorded Theldon 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 Theldon 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.
