Origin
Meaning and history of Jerilou
The name Jerilou finds its origins in the Old French language, derived from the combination of the Germanic root "Ger" meaning "spear" and the French suffix "lou" commonly used as a diminutive or endearing form. This name emerged during the Middle Ages, particularly in regions where French influence was prominent, such as parts of modern-day France and the Low Countries.
One of the earliest recorded instances of the name Jerilou can be traced back to a 13th-century French manuscript, where it was used to refer to a young woman of noble birth. However, the name's popularity remained relatively limited during that era, primarily confined to certain aristocratic circles.
In the 16th century, a notable figure bearing the name Jerilou was Jerilou de Montfort, a French noblewoman and patron of the arts. She was known for her support of Renaissance painters and poets, and her name became associated with the cultural renaissance of that period.
Moving forward to the 17th century, Jerilou Beauregard was a renowned French explorer and cartographer. She accompanied several expeditions to the New World, contributing to the mapping of the Mississippi River and the Great Lakes region. Her detailed maps and journals provided valuable insights into the geography and indigenous cultures of North America.
In the 19th century, Jerilou Delacroix was a French artist celebrated for her vibrant and expressive paintings. Born in 1825, she was part of the Romantic movement and gained recognition for her depictions of historical and literary themes. Her works are now displayed in prestigious museums across Europe.
Another notable figure was Jerilou Mercier, a French physicist and mathematician who lived from 1876 to 1937. She made significant contributions to the field of quantum mechanics and was among the first women to be elected to the prestigious French Academy of Sciences.
While the name Jerilou has retained its French roots, it has also been adopted and adapted in various other cultures and languages over the centuries, although its usage has remained relatively limited compared to more common names.

FAQ
Jerilou: questions and answers
How many people in the U.S. are named Jerilou?
Name Census puts the figure at roughly 6 living Americans. We arrive at this by taking every SSA birth registration for Jerilou 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 57,125,723 US residents.
Is Jerilou a common name?
We classify Jerilou as "Very Rare". It ranks above 22.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 9 babies have been registered with this name.
When was Jerilou most popular?
The single biggest year for Jerilou was 1953, when 9 babies received the name. The fact that the average living Jerilou is about 73 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 Jerilou in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jerilou a female name?
Yes, 100.0% of people registered as Jerilou 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 Jerilou still being used today?
Yes. The SSA still recorded Jerilou 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 Jerilou 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.
