The Spanish surname Ruiz is a patronymic from the personal name Ruy, a short form of Rodrigo, meaning "son of Roderick". [1] [2] Roderick's roots can be traced back to the Visigoths, the Germanic tribe which ruled in the Iberian Peninsula between the 5th and 8th centuries;[ citation needed ] it originates from the Germanic personal name "Hrodric" which is composed of the elements "Hrōd", meaning "renown", and "rīc", meaning "power(ful)", thus "famous ruler".
