Origin
Meaning and history of Delfinia
The name Delfinia has its origins in the Latin language and is derived from the word "delphinus," which means "dolphin." This connection to the marine mammal suggests that the name may have been initially used in coastal regions where dolphins were commonly seen or held cultural significance.
One of the earliest recorded instances of the name Delfinia can be found in ancient Roman texts, where it was sometimes used as a feminine form of the name Delphinus. However, its usage was relatively rare during this time period.
In the Middle Ages, the name Delfinia gained some popularity in certain parts of Europe, particularly in regions with strong maritime traditions or connections to the Mediterranean Sea. It was occasionally bestowed upon individuals born near the sea or those whose families had ties to fishing or seafaring occupations.
One notable historical figure bearing the name Delfinia was Delfinia of Aragon (1324-1381), a Spanish noblewoman and the daughter of King Alfonso IV of Aragon. Her name likely reflected the maritime heritage of the region and the cultural influences present at the time.
Another noteworthy individual was Delfinia Guzmán (1559-1598), a Spanish nun and mystic known for her religious writings and her work in establishing convents in Seville. Her name may have been chosen as a nod to the city's coastal location and its rich seafaring history.
In the 17th century, Delfinia Hidalgo (1612-1682) was a Spanish painter and one of the few female artists of her time to gain recognition. Her name, while uncommon, may have been inspired by the artistic and cultural traditions of the region.
Moving forward in history, Delfinia Bunge (1875-1952) was an Argentine writer and feminist known for her contributions to literature and her advocacy for women's rights. Her name likely reflected the diverse cultural influences present in Argentina at the time.
Lastly, Delfinia Ovando (1888-1974) was a Bolivian educator and activist who fought for the rights of indigenous people and played a significant role in the country's education system. The name Delfinia may have held special meaning or symbolism within her cultural background.
Overall, while the name Delfinia has remained relatively uncommon throughout history, it has been carried by individuals from various backgrounds and regions, often reflecting cultural ties to the sea, maritime traditions, or artistic and literary influences.

FAQ
Delfinia: questions and answers
How many people in the U.S. are named Delfinia?
Name Census puts the figure at roughly 2 living Americans. We arrive at this by taking every SSA birth registration for Delfinia 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 171,377,169 US residents.
Is Delfinia a common name?
We classify Delfinia as "Very Rare". It ranks above 4.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 46 babies have been registered with this name.
When was Delfinia most popular?
The single biggest year for Delfinia was 1930, when 8 babies received the name. The fact that the average living Delfinia is about 114 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 Delfinia in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Delfinia a female name?
Yes, 100.0% of people registered as Delfinia 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 Delfinia still being used today?
Yes. The SSA still recorded Delfinia 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 Delfinia 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.
