Babies given each name, 1880–2025
Sieara Sienna
Each line is every baby given the name that year, girls and boys added together — the only count that means the same thing for both names. A line breaks where the name fell below five babies in a year — the point at which the SSA stops publishing it — rather than being drawn through a figure nobody published. A single published year in a gap shows as a dot.
Who was ahead
Sienna has been the commoner name in every year either was published, 1960 to 2025. The lead has never changed hands.
The closest they came was 1986, when Sieara had 13 and Sienna had 23.
