Babies given each name, 1880–2025
Cirildo Cirilo
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.

Cirilo has been the commoner name in every year either was published, 1915 to 2025. The lead has never changed hands.
