Gardea
A likely Spanish surname, probably from a place-name or a word for a guarded or protected place.
The #8,688 most common surname in the United States (2010 Census) — about 1 in every 81,657 Americans shares it.
Etymology
Gardea is most likely a Spanish-language surname, though its exact origin is not firmly documented in the usual surname dictionaries. It may be related to the Romance root seen in Spanish and Catalan words for a guard, watch, or protected enclosure, and could have begun as a place-based name or a descriptive byname for someone connected with guarding. In some cases, surnames of this shape also reflect local place-names rather than a direct common-word meaning.
History
The surname is found in Hispanic communities, especially in the Americas, where Spanish surnames were carried through colonial-era settlement and later migration. Because no direct historical dictionary entry is available here, its precise regional origin in Spain or Spanish America remains uncertain. Modern bearers in the United States likely reflect Mexican or broader Latin American family lines, but that should be treated as a general pattern rather than a firm rule.

Fun fact
Names that look like common Spanish words are often actually tied to old place-names, so the same surname can have more than one local origin.
