Origin
Meaning and history of Aloysuis
The name Aloysius derives from the Old French name "Loys", which itself comes from the Old Frankish "Chlodovech". This name can be traced back to the 5th century and the Merovingian dynasty of Frankish kings. The name is a compound of the Germanic elements "hlud" (famous) and "wik" (battle or warrior).
The name Aloysius gained popularity due to its association with St. Aloysius Gonzaga, a 16th-century Italian Renaissance prince who became a member of the Jesuit order. He was canonized in 1726 by Pope Benedict XIII. The name began to spread across Catholic Europe after his canonization.
One of the earliest recorded examples of the name is Aloysius Lilius, an Italian astronomer and philosopher who is credited with designing the Gregorian calendar in 1582. Another notable early bearer of the name was Aloysius Gonzaga (1568-1591), the Jesuit saint for whom St. Aloysius Gonzaga was named.
Throughout history, several notable figures have borne the name Aloysius. These include Aloysius Bertrand (1807-1841), a French Romantic poet; Aloysius Habets (1857-1924), a Dutch Jesuit priest and historian; Aloysius Stepinac (1898-1960), a Croatian cardinal and Archbishop of Zagreb; Aloysius Ambrozic (1930-2023), a Canadian Roman Catholic prelate; and Aloysius Pang (1990-2023), a Singaporean actor and army corporal.
Aloysius has been a popular name in various Catholic communities around the world, particularly in Italy, France, Spain, and parts of Central and Eastern Europe. It has also seen some use in English-speaking countries, though to a lesser extent.

FAQ
Aloysuis: questions and answers
How many people in the U.S. are named Aloysuis?
Name Census puts the figure at roughly 4 living Americans. We arrive at this by taking every SSA birth registration for Aloysuis 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 85,688,585 US residents.
Is Aloysuis a common name?
We classify Aloysuis as "Very Rare". It ranks above 6.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 114 babies have been registered with this name.
When was Aloysuis most popular?
The single biggest year for Aloysuis was 1927, when 11 babies received the name. The fact that the average living Aloysuis is about 99 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 Aloysuis in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Aloysuis a male name?
Yes, 100.0% of people registered as Aloysuis 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 Aloysuis still being used today?
Yes. The SSA still recorded Aloysuis 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 Aloysuis 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.
