About the name Jill
Jill belongs to the English & American tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess. It travels in a few spellings: Gillian.
In the United States, Jill first appears in Social Security records in 1906. It climbed to its best-ever rank of #41 in 1977, and in 2024 19 babies received the name — 208,052 in total since 1880. Those are the official counts, not estimates.
