About the name Sadaf
Sadaf belongs to the Muslim & Arabic 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, Sadaf first appears in Social Security records in 1976. It climbed to its best-ever rank of #4099 in 1987, and in 2024 27 babies received the name — 640 in total since 1880. Those are the official counts, not estimates.
