Origin
Meaning and history of Lucill
The name Lucill has its origins in the Latin language and culture, dating back to ancient Roman times. It is derived from the Latin word "lux," which means light or radiance. The name Lucill is believed to be a feminine form of the masculine name Lucius, which was a popular Roman praenomen or personal name.
One of the earliest recorded instances of the name Lucill can be found in the writings of the ancient Roman philosopher and statesman Cicero, who lived from 106 BC to 43 BC. Cicero mentions a woman named Lucill in his letters, suggesting that the name was in use during the late Roman Republic period.
In the early Christian era, the name Lucill gained popularity among followers of the Christian faith. One notable figure was Saint Lucill, a fourth-century martyred virgin from Córdoba, Spain. Her feast day is celebrated on June 23rd in the Catholic Church.
During the Middle Ages, the name Lucill continued to be used, albeit less frequently than in ancient times. One prominent bearer of the name was Lucill of Merania (c. 1181-1240), a German noblewoman who was the wife of King Louis I of Bavaria.
In the Renaissance period, the name Lucill experienced a resurgence in popularity, particularly among the intellectual and artistic circles of Italy. One famous bearer of the name was the Italian poet and satirist Lucill Minerbi (1469-1529), known for her witty and biting verse.
Another notable figure was the French philosopher and essayist Lucill de la Vergne, Comtesse de Lafayette (1634-1693), whose novel "La Princesse de Clèves" is considered a masterpiece of French literature.
In the 18th century, the name Lucill was popularized by the English poet and dramatist Lucill Piozzi (1739-1821), known for her literary salons and her friendship with the renowned lexicographer Samuel Johnson.
During the 19th century, the name Lucill gained popularity in the United States, with one notable bearer being the American writer and feminist activist Lucill Stone (1809-1900), who was a prominent figure in the women's suffrage movement.

FAQ
Lucill: questions and answers
How many people in the U.S. are named Lucill?
Name Census puts the figure at roughly 7 living Americans. We arrive at this by taking every SSA birth registration for Lucill 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 48,964,905 US residents.
Is Lucill a common name?
We classify Lucill as "Very Rare". It ranks above 23.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 235 babies have been registered with this name.
When was Lucill most popular?
The single biggest year for Lucill was 1920, when 18 babies received the name. The fact that the average living Lucill is about 95 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 Lucill in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Lucill a female name?
Yes, 100.0% of people registered as Lucill 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 Lucill still being used today?
Yes. The SSA still recorded Lucill 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 Lucill 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.
