Babies given each name, 1880–2025
Gwyn Gwyndolyn
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.

Of the 106 years in which either name was published, Gwyn for 93 years and Gwyndolyn for 13 years. The lead changed hands 14 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.
