Irish
girl names.

Within the Irish girl side specifically, Kathleen, Kelly, and Erin are the most-used in the U.S. record — a useful three-point sense of the register, since the rest of the list mostly varies between rarer literary, religious, and modern coinages.

This page shows 12 Irish girl names sorted by U.S. SSA totals — so the most-given names sit at the top and the rarer entries toward the bottom.
