About the name Diogo
Diogo belongs to the Portuguese 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, Diogo first appears in Social Security records in 2001. It climbed to its best-ever rank of #1842 in 2004, and in 2024 8 babies received the name — 441 in total since 1880. Those are the official counts, not estimates.
