About the name Teresa
Teresa 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, Teresa first appears in Social Security records in 1880. It climbed to its best-ever rank of #18 in 1961, and in 2024 310 babies received the name — 415,746 in total since 1880. Those are the official counts, not estimates.
