About the name Marcelino
Marcelino 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, Marcelino first appears in Social Security records in 1888. It climbed to its best-ever rank of #831 in 1929, and in 2024 103 babies received the name — 7,372 in total since 1880. Those are the official counts, not estimates.
