Meaning
from the word sincere, genuine and honest
The story
Sincere is the English word on a birth certificate, genuine and heartfelt, and the record dates its arrival as a name to a single generation: 189 boys in the 1990s, 2,899 in the 2000s, 4,142 across the 2010s, 2,860 so far this decade, with a girls' column alongside at 595 in the 2000s. The word itself has a story worth telling at the dinner table: it comes through Middle French from the Latin sincerus, "genuine," and the beloved tale that it means "without wax," from sculptors patching flawed marble, is officially folk etymology, flagged as such by the dictionaries. Which seems fitting: a name meaning genuine, trailed by a famous story that is not. Virtue names run in every era's blood, from Faith to Justice; Sincere is the modern branch, direct as a handshake, and the record shows it arrived all at once.

share of that year’s name registrations
First given names from provincial and territorial vital statistics across Canada; any name-sex-year under 5 is excluded at source, and small Quebec counts carry a randomized adjustment made at source. Shares divide by Statistics Canada’s count of live births for the year; the 2024 count is preliminary. Source: Statistics Canada, first names at birth (table 17-10-0147-01)
Not on the record in Spain, Mexico City, Argentina, Puerto Rico, England and Wales, Ireland, New Zealand, Scotland and Poland: 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.
