Origin
Meaning and history of Marioni
The name Marioni is a variant of the Italian name Marione, which has its roots in the Latin name Marianus. This name is derived from the Roman family name Marius, which is believed to have originated from the Latin word "mas," meaning male or masculine. The name Marioni gained popularity during the Middle Ages in Italy and other parts of Europe influenced by Italian culture.
In ancient Roman history, the name Marius was associated with several notable figures, including Gaius Marius, a renowned Roman general and statesman who lived from 157 BC to 86 BC. He played a significant role in the Jugurthine War and the Social War, and his military reforms helped shape the Roman army.
One of the earliest recorded examples of the name Marioni can be found in the 12th century. Marioni di Buonaccorso was an Italian painter and architect who lived from around 1150 to 1230. He is known for his contributions to the architectural design of the Siena Cathedral in Tuscany, Italy.
Another notable figure with the name Marioni was Marioni di Piero, an Italian painter from the Renaissance period who lived from around 1420 to 1495. He was active in Florence and is known for his religious paintings and frescoes adorning various churches in the region.
In the 16th century, Marioni Alberti was an Italian mathematician and physicist from Venice. He lived from 1522 to 1601 and made significant contributions to the field of mechanics, including the study of projectile motion.
During the 17th century, Marioni Fontana was an Italian architect and sculptor who lived from 1628 to 1714. He is renowned for his work on the Basilica of St. Peter in Rome, where he designed the famous Altar of the Chair and contributed to other decorative elements.
In more recent history, Marioni Rampolla was an Italian prelate who lived from 1843 to 1913. He served as the Secretary of State for Pope Leo XIII and was considered a leading candidate to become the next Pope in the 1903 conclave, but his election was reportedly vetoed by Emperor Franz Joseph I of Austria.

FAQ
Marioni: questions and answers
How many people in the U.S. are named Marioni?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Marioni 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 34,275,434 US residents.
Is Marioni a common name?
We classify Marioni as "Very Rare". It ranks above 28.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10 babies have been registered with this name.
When was Marioni most popular?
The single biggest year for Marioni was 2006, when 5 babies received the name. The fact that the average living Marioni is about 19 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 Marioni in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Marioni a male name?
Yes, 100.0% of people registered as Marioni 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 Marioni still being used today?
Yes. The SSA still recorded Marioni 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 Marioni 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.
