History & Origin

Mareo most often reads as a variant of Mario, the Italian name from the Roman Marius, though it is also a genuine Japanese masculine name. Because the routes differ, its origin is uncertain, and it appeared only rarely in American records.

It was never common, given to only about sixteen boys a year at its peak around 1980. A boy named Mareo then is in his forties today.

Did you know? Mareo sits at a crossroads of two naming worlds, echoing the Italian Mario on one side and standing as an independent Japanese given name on the other.
