Babies given each name, 1880–2025
Kileigh Kilian
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 47 years in which either name was published, Kilian for 40 years and Kileigh for 7 years. The lead changed hands 8 times.

A rank is a position within one sex’s list for one year, so the two rank rows are not subtracted from one another and the winning column is not marked on them. The living figure is a life-table estimate, not a count.
Which name is older
Half of the Kileighs alive today are over 19; half the Kilians are over 7. That is 12 years between them: two names in use at the same time, worn by two different generations.
