History & Origin

Fidelia comes from Latin fidelis, 'faithful' — the feminine counterpart of Fidel. It belongs to the family of Christian virtue names alongside Constance and Verity, and has been used in Spanish-speaking countries and, sparingly, in English. Today it reads as an antique, warm-hearted choice (said 'fih-DEE-lee-uh').

It appears only rarely in U.S. records. Rare, antique, and full of meaning.

Did you know? Fidelia shares its root with 'fidelity' and with Fido, the old dog's name — all from Latin fidelis, 'faithful'. As a girls' name it wears that meaning plainly: loyal (said 'fih-DEE-lee-uh').
