Source: US Social Security Administration baby-name data, 1880 to 2025, as published in 2026. Each spelling is counted separately, a name given to fewer than 5 babies of one sex in a year is left out, and few people born before 1937 have records, which is why the chart shows babies per million rather than raw counts.
