Pietro
Meaning
rock; a trendy pick in Brazil recently, part of a wave of Italian-spelling revivals alongside Enzo and Valentina
The story
Pietro is the Italian form of Peter, the apostle's name built on the Greek petros, and its early American story was the immigrant chapter: 140 boys in the 1910s, 171 in the 1920s, then a long quiet midcentury. The twist is where the name's twenty-first century got loud, an ocean south of both Rome and New York. Brazil's 2022 census counts 141,070 residents named Pietro with a median age of six; 81,908 of them were born in the 2010s alone, a decade in which the American register logged 349. The name rode Brazil's wave of Italian-spelling revivals alongside Enzo and Valentina, and it rode it hard. The American columns have warmed politely, 349 in the 2010s and 215 so far this decade, but make no mistake about where this name's new chapter is being written. It is being written in Portuguese.
