About brazilian names
Double surnames are the norm in results like "Milton Bonfim Cardoso" and "Wanda Fonseca de Freitas", and a Japanese middle surname, as in "Pedro Sato Aguiar", reflects São Paulo's immigrant generations. Keep both family names for formal documents and drop to one in dialogue, the way Brazilians actually do. The range supports telenovela casts, favela narratives, and football squads alike.
How brazilian names are built
Every result is three parts: one given name plus two surnames. The male and female templates differ only in the given-name bank, each followed by the same two surname slots. The given banks hold 154 male and 208 female first names, and both surname slots draw from matched 216-entry pools, producing pulls like Ademir Guerreiro Abril, Vinicius Coelho Carpinteiro and Veronica Carrico Branco.
Ademir Guerreiro Abril
Ademir (given, male bank) + Guerreiro (first surname, nmf bank) + Abril (second surname, nmf2 bank)
Veronica Carrico Branco
Veronica (given, female bank) + Carrico (first surname, nmf bank) + Branco (second surname, nmf2 bank)
Vinicius Coelho Carpinteiro
Vinicius (given, male bank) + Coelho (first surname, nmf bank) + Carpinteiro (second surname, nmf2 bank)

Naming notes
The two-surname tail makes the output longer than a single first-plus-last name: a given name followed by one draw from the 216-entry nmf bank and one from the 216-entry nmf2 bank. The two surname banks are equal in size, and the female given bank (208) is larger than the male (154).
Questions about brazilian names
- Why do these names have two surnames?
- The template appends two surname slots after the given name, drawing one from the nmf bank and one from the nmf2 bank, so every result is given name plus two surnames.
- Are the two surname banks the same size?
- Yes, 216 entries each, while the given banks differ at 154 male and 208 female.
- Can I use these names freely?
- Yes. The bank entries are treated as plain name data, so the three-part combinations are free for characters and worldbuilding, though each full combination is generated rather than tied to one person.
