Babies given each name, 1880–2025
Dalan Daleyza
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
Of the 48 years in which either name was published, Dalan for 34 years and Daleyza for 14 years. The lead changed hands once.
