Coreas
Coreas is most likely a patronymic or family-name form that developed in Spanish-speaking communities, with the exact origin depending on the family line.
The #9,633 most common surname in the United States (2010 Census) — about 1 in every 91,643 Americans shares it.
Etymology
No specific dictionary entry is available here, so the surname has to be treated cautiously. Coreas is likely a Hispanic surname shaped by Spanish naming patterns, possibly as a pluralized or patronymic family form derived from an older personal name or place-name root. In many cases like this, the ending -as is part of a surname that evolved through local pronunciation and spelling rather than a single transparent dictionary word.
History
The surname is found in modern Hispanic and Latino populations, especially in the Americas. Because no authoritative historical entry is available in the provided corpus, its deeper family history is best traced through regional records, church registers, and immigration documents rather than through a single standard etymology. The modern distribution suggests survival through family lines in Spanish-speaking diaspora communities.
