About the name Theresa
Theresa belongs to the French 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.
In the United States, Theresa first appears in Social Security records in 1880. It climbed to its best-ever rank of #32 in 1956, and in 2024 145 babies received the name — 404,471 in total since 1880. Those are the official counts, not estimates.
