Marcelo
Meaning
young warrior (propagandist Marcelo del Pilar)
The story
Marcelo is the Marcellus line worn across the Spanish and Portuguese worlds, the old Roman family name tradition reads as a young Mars, a young warrior. The Philippines gave it a hero, the reformist writer Marcelo del Pilar, and Brazilian soccer gave it a left back so famous one name sufficed. The American record is a staircase with almost no landings: about 68 boys in the 1910s, a few hundred a decade at midcentury, 1,300 in the 1990s, 2,200 in the 2000s, 3,400 in the 2010s, and 3,520 so far this decade, already past the full 2010s. In our records it goes to boys about 13,200, without one recorded girl. Rome named the boy, three continents raised him, and the record is still climbing.
