About the name Rui
Rui belongs to the Portuguese and Japanese 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, Rui first appears in Social Security records in 1967. It climbed to its best-ever rank of #2106 in 1971, and in 2024 62 babies received the name — 838 in total since 1880. Those are the official counts, not estimates.
