History & Origin

Hilaria comes from Latin hilaris, 'cheerful', the feminine of Hilarius — the name of Saint Hilary of Poitiers, a fourth-century bishop. The Roman Hilaria festival marked the joy of spring. The name lives on in Spanish as Hilaria and in Italian as Ilaria, and it reads as a warm, antique choice (said 'hih-LAR-ee-uh').

It appears only rarely in U.S. records. Rare, cheerful, and antique.

Did you know? The Romans had a spring festival called the Hilaria — days of rejoicing. The same root gives us 'hilarious' and the name Hilary, and Hilaria is its bright feminine form (said 'hih-LAR-ee-uh').
