About the name Rhea
Rhea 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, Rhea first appears in Social Security records in 1882. It climbed to its best-ever rank of #363 in 1893, and in 2024 484 babies received the name — 19,281 in total since 1880. Those are the official counts, not estimates.
