Dominguez
A Spanish patronymic surname meaning “son of Domingo,” ultimately from the Latin name Dominicus, “of the Lord.”
The #254 most common surname in the United States (2010 Census) — about 1 in every 2,588 Americans shares it.
Etymology
Domínguez is a patronymic surname built from the personal name Domingo, with the ending -ez meaning “son of” in Spanish surname formation. Domingo comes from Latin Dominicus, meaning “belonging to the Lord” or “of the Lord.” In origin, the name was likely given because the child was born on Sunday or in a religious context connected with the Lord’s day.
History
The surname is common throughout the Spanish-speaking world and is especially frequent in Spain and Latin America. Historical sources also show it in medieval Iberian records, where it appears as a true patronymic, “son of Domingo.” The spelling without an accent, Dominguez, is standard in English-language contexts, though the Spanish form is usually Domínguez.
