Casarez
A Hispanic surname most likely linked to a place name built from Latin roots for a house or dwelling.
The #4,927 most common surname in the United States (2010 Census) — about 1 in every 43,242 Americans shares it.
Etymology
Casarez is most plausibly a Spanish-language surname formed from a place-name base related to casa, meaning "house" or "dwelling," ultimately from Latin casa. The final -ez-like shape may reflect regional spelling or adaptation rather than a standard patronymic ending. Because this surname is relatively uncommon and not well documented in the classic English-language surname dictionaries, its precise origin is uncertain, but it fits a broad Hispanic locational pattern.
History
The surname is found mainly in Spanish-speaking communities and in the United States, especially among families of Mexican or broader Hispanic heritage. Its current spelling may reflect regional pronunciation or later orthographic variation from an older local form. As with many Hispanic surnames, it may have been stabilized in records only after migration and civil registration.

Fun fact
Because it ends in -ez, many people assume it must be a patronymic surname like Hernández or González, but Casarez is more likely linked to a place or house-name than to "son of" formation.
