Gwendlyon Gwenn

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

Gwenn has been the commoner name in every year either was published, 1918 to 2022. The lead has never changed hands.

The closest they came was 1941, when Gwendlyon had 9 and Gwenn had 14.

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 Gwendlyons alive today are over 73; half the Gwenns are over 64. That is 9 years between them: two names in use at the same time, worn by two different generations.
