About the name Gretta
Gretta 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.
In the United States, Gretta first appears in Social Security records in 1881. It climbed to its best-ever rank of #800 in 1895, and in 2024 32 babies received the name — 4,116 in total since 1880. Those are the official counts, not estimates.
