Thulio
Meaning
a Brazilian spelling of Túlio, the Portuguese form of the Roman family name Tullius, whose meaning is unknown; the Th at the front belongs to the same 1980s and 1990s wave as Thiago and Thaís, and Brazil's 2022 census counts about 1,500 people, more of them born in the 1990s than in any other decade

Not on the record in Spain, 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 Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. 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.
