Origin
Meaning and history of Aloysious
The name Aloysious is derived from the Old German name Alwis or Aloiz, which means "famous in battle" or "renowned warrior." The name entered the Romance languages through the Latinized form Aloysio or Aloysius.
The name gained popularity in the Christian tradition due to St. Aloysius Gonzaga (1568-1591), an Italian Renaissance nobleman who became a member of the Jesuit order. He is the patron saint of young students and is known for his piety and devotion to the Catholic faith.
One of the earliest recorded examples of the name Aloysious can be found in the writings of the Roman historian Tacitus, who mentioned a German chieftain named Alwis in his work "Annals" from the 1st century AD.
Throughout history, there have been several notable individuals with the name Aloysious. Aloysious Lilius (1510-1576) was an Italian astronomer and philosopher who contributed to the development of the Gregorian calendar. Aloysious Bertrand (1807-1841) was a French missionary priest who worked in various islands of the Pacific Ocean.
Aloysious Xavier Wibaux (1833-1887) was a Belgian-American rancher and businessman who played a significant role in the development of the cattle industry in what is now eastern Montana. Aloysious Michaels (1870-1952) was an American baseball player who played in the major leagues from 1890 to 1899.
Aloysious Stepinac (1898-1960) was a Croatian Catholic cardinal who was beatified by Pope John Paul II in 1998 for his courageous defense of human rights during World War II and the communist regime in Yugoslavia.

FAQ
Aloysious: questions and answers
How many people in the U.S. are named Aloysious?
Name Census puts the figure at roughly 3 living Americans. We arrive at this by taking every SSA birth registration for Aloysious 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 114,251,446 US residents.
Is Aloysious a common name?
We classify Aloysious as "Very Rare". It ranks above 4.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 98 babies have been registered with this name.
When was Aloysious most popular?
The single biggest year for Aloysious was 1919, when 10 babies received the name. The fact that the average living Aloysious is about 116 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 Aloysious in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Aloysious a male name?
Yes, 100.0% of people registered as Aloysious 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 Aloysious still being used today?
Yes. The SSA still recorded Aloysious 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 Aloysious 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.
