Ruiz surname meaning

Ruiz is a Spanish and Portuguese patronymic meaning “son of Ruy.” Ruy was a short form of Rodrigo, so the surname preserves an ancestor’s familiar given name rather than naming an occupation or a place. Roiz and Rodrigues belong to the wider set of Iberian forms related to Rodrigo, though they are not interchangeable in every family tree.

Rodrigo ultimately has Germanic roots often glossed as fame and power. That deeper history explains the personal name but is not necessary to read Ruiz. Type parent's name is clear, and the spelling Ruiz should not be used by itself to infer one specific region, class, or migration story among the many families recorded in the United States.
