Meaning
“Brazilian form of Tatiana, from the Roman family name Tatius, of unknown meaning; borne by a 3rd-century saint”
The story
Tatiane is Brazil's own spin on Tatiana, and its census profile is one of the sharpest generation portraits in the whole record. Of 194,275 residents carrying the name in 2022, 100,614 were born in the 1980s, more than half of the name's entire population from a single decade, with a median age of 35 to match. The trail behind it is long: Tatiana descends from the Roman family name Tatius, of unknown meaning and possibly Sabine, carried by a third-century saint especially venerated in Orthodox Christianity, which is how Russia came to love the name before Brazil did. Brazil then did what Brazil does, trading the final a for an e and making the name its own. The steeplechase runner Tatiane Raquel da Silva carries it on the track today. The register has moved on, 345 so far this decade, which only sharpens the portrait: some names mark a generation the way a song does.

Montevideo City

Tatiane is not on the 2011 record for Montevideo, whose registry withholds nothing, so the spelling was not given there that year.
The count never rose above 1 in a year, too few to chart.

Not on the record in Mexico City, Argentina, Puerto Rico, England and Wales, Canada, Ireland, New Zealand and Scotland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years.
