From “Rolanda” to “Thaoã”, Brazilians Share Curiosities Behind Such Rare Names That Don’t Even Appear on the Official IBGE List.
Brazilians with Rare Names Challenge the IBGE and Reveal Stories Full of Curiosities
Names like Rolanda, Thátner, Kraucer, and Thaoã are catching attention in Brazil after the IBGE released the new ranking of name popularity in the country.
The survey, based on the 2022 Census, listed the most common names registered in civil registries. However, those appearing in less than 20 registrations in the Civil Registry were hidden for statistical confidentiality — and that’s precisely where the most curious stories arise.
These Brazilians, whose names do not even appear in the IBGE public database, shared with g1 the unusual and affectionate origins behind the choices made by their parents and grandparents. In many cases, there are family tributes, memory lapses, and even television inspirations.

IBGE Confidentiality Hides Names with Fewer Than 20 Registrations in Brazil
The Brazilian Institute of Geography and Statistics (IBGE) confirmed that, for privacy reasons, it does not disclose names used by fewer than 20 people. This rule protects citizens’ identities and prevents individual data from being tracked.
But the curiosity of Brazilians went beyond statistics: those who carry these rare names decided to share their stories and, as a bonus, show the affectionate and even humorous side behind the Civil Registry.
Rolanda, the Heiress of a Family Tradition
Among the unusual names, Rolanda Marla Costa, from Rio de Janeiro, carries a family legacy.
“It’s a traditional family name. My great-grandfather was Rolando, my grandfather was Rolando, and my father is Rolando,” she said. Thus, Rolanda kept alive a tradition that spans generations and preserves an emotional bond with her roots.
Milvon Júnior: When the Tribute Won’t Continue
Another curious case is Milvon Júnior, from Campinas (SP).
“My name is Milvon. Not just that. Milvon Júnior because my father is also named Milvon,” he explained. The name originated from an adaptation made by his grandfather, Milton, who sought something similar to his own name. “My dad wanted to make this tribute, but I promise, this name won’t continue,” jokes the resident.
Junian and the Desire for Similarity with His Brother
The Paraná resident Junian Freitas, from Ponta Grossa, received a name purely inspired by his brother.
“My mom wanted a name similar to my brother’s. His name is Júnior,” he revealed. The result was an invented name, sonorously similar, that made him unique in the country.
Delinir: When Forgetting Became Baptism
The story of Delinir Padilha, from Contenda (PR), is a classic example of paternal improvisation.
“The origin of my name, my mom said, is that my dad forgot. It was supposed to be Débora,” she said, laughing. Even Google seems not to understand the name. “Even Google corrects me: ‘Did you mean DEFINE’,” she recounted.
Thátner: The Name That Came from TV
In Belo Horizonte, Thátner Gomes explains that his name was born purely from sound.
“My dad heard it on television, thought it was beautiful and different, went straight to the registry office to register it and wrote it down the way he heard,” he said. Thus, the name came to life — with a unique spelling and no defined origin.
Morrisson, the Name Inspired by an Argentine City
The resident of Brasília Morrisson Mazzucco carries a name that sounds foreign but has a national story.
“The suggestion came from my dad. He studied at a seminary in the city of Morrison, in the province of Córdoba, Argentina,” he explained. The result: a rare name that honors a memory from his father’s youth — and has nothing to do with the famous singer Jim Morrison.
Kraucer and Naziara: The Neighbors and Inspiring Parents
In Brasília, Kraucer Fernandes says his name came from living nearby.
“I asked my parents and they told me it would be a neighbor with a similar name, but to this day I haven’t found anyone with the same name as mine,” he revealed.
Meanwhile, Naziara Santos, from Aracaju, explains that hers is a derivation from her father’s name: “Because of my father’s name, which is Nazian,” she said proudly.
Thaoã and Ariolan: Meanings Lost in Time
Among the most mysterious names are Thaoã and Ariolan.
“According to my mom, it means son of the moon, but she doesn’t quite remember where this name came from,” said Thaoã Barbosa, from Rio de Janeiro.
Married to Rhanda Santos, he jokes that his wife’s name also came from a creative mistake: “My mom understood Rhanda, but it was Hanna, like Hanna Montana. And she spelled it with RH, the Brazilian way of naming children.”
Meanwhile, Ariolan, a lawyer from Caicó (RN), states: “I don’t know the exact origin of this name, I just know that my mom decided to name me Ariolan and that’s what she did.”
