Meaning & origin

Otilio is an unusual masculine name with Spanish and Italian roots, derived from the Latin Otho, which traces back to a Germanic word for 'wealth' or 'fortune'. In the United States, its recorded usage began in 1925, but it has remained exceptionally rare. The name reached its peak popularity in 1978, though still with only a handful of births. Despite its scarcity, Otilio has maintained a steady, if minimal, presence. Its trajectory shows stability over the decades, never experiencing a boom or revival. The name is almost entirely unknown in the U.S. outside of Spanish-speaking communities, and no top states have recorded enough births to register. For parents seeking a distinctive historical name with a melodic sound, Otilio offers a unique alternative to more common Italian and Spanish choices.

Otilio is a Spanish and Italian name derived from the Latin name Otho, which itself likely originates from a Germanic element meaning 'wealth' or 'fortune'. The name appears in early Christian history via Saint Otilio, a 7th-century Frankish abbot. It has been used sporadically in Spanish-speaking countries, particularly in the mid-20th century, though it never reached widespread popularity. Its usage in the United States has been extremely rare, with only a handful of recorded births since 1925.
