Contreras
A Spanish surname originally from a place-name, referring to someone from Contreras or Contreras-style locales.
The #229 most common surname in the United States (2010 Census) — about 1 in every 2,372 Americans shares it.
Etymology
Contreras is a Spanish surname of locational origin. It most likely began as an identifying name for someone who came from a place called Contreras, of which there are several in Spain. The place-name itself is generally treated as pre-Roman or otherwise obscure in origin, so the surname is best understood as “from Contreras,” rather than as a word with a transparent modern meaning.
History
The surname is long established in Spain and later spread widely through Spain’s overseas empire, especially to Spanish America. It is common enough today to rank high in the United States, reflecting Hispanic migration rather than a single family line. Historical name lists from the sources provided show the surname in use in Spanish-speaking contexts, but they do not add new etymological detail.
