Spanish surnames developed from patronymics, places, occupations, nicknames, and personal descriptions. Many familiar names are medieval, but a surname meaning cannot carry a documented family line back to Rome or the Visigoths on its own.

Two Surnames in the Spanish-Speaking World
In the traditional Spanish order, a person’s first surname is the first surname of the father, and the second surname is the first surname of the mother. If the mother is María Díaz Hernández and the father is Julio Martínez Rodríguez, their child would traditionally be Martínez Díaz.
Modern law and practice can allow parents to choose the order, and customs vary across Spanish-speaking countries. Once the order is chosen for one child, local rules may require the same order for siblings. Women generally retain their birth surnames, although social styles involving a husband’s surname exist in some countries.
Patronymic Surnames
Many Spanish patronymics end in -ez, with related historical forms in -az, -iz, and -oz. They are often glossed as “son of,” but the safest interpretation is that the surname was formed from a personal name. Once hereditary, it no longer identified the bearer’s actual father.
Rodríguez — A patronymic from Rodrigo. Rodrigo comes from a Germanic personal name whose elements are generally associated with “fame” or “glory” and “ruler” or “power.” That etymology does not make Rodríguez literally “famous power.”
Fernández — A patronymic from Fernando. Fernando is a Germanic personal name, but its exact elemental interpretation is debated. “Brave traveler” is a traditional gloss, not a certain biography of the name’s first bearer.
González — A patronymic from Gonzalo, from the medieval name Gundisalvus. The older name is Germanic, but proposed meanings of its elements vary. It is safer to say “descendant of Gonzalo” than to claim a complete translation.
García — García is an old Iberian personal name and surname, especially associated with northern Spain. A Basque connection is often proposed, but the ultimate etymology is uncertain. The claim that it securely comes from gaztea and means “young warrior” should not be stated as fact.
Martín — Martín comes from Latin Martinus, a name related to Mars, the Roman god of war. As a surname it may be patronymic or derive from the personal name in another way.
López — A patronymic from Lope. Lope is connected with Latin lupus, “wolf,” so the historical formation is better understood as “descendant of Lope” than the literal “son of the wolf.”
Sánchez — A patronymic from Sancho. The personal name has been connected with Latin Sanctius and sanctus, “holy,” but “son of the blessed” is too literal and too certain.
Pérez — A patronymic from Pero or Pedro, the Spanish forms related to Peter. The biblical name Perez or Peretz is a separate Hebrew name. Some Sephardic families bear Pérez, but the common Spanish patronymic cannot be treated as evidence of Jewish ancestry or as a surname adopted generally during the Inquisition.
Martínez — A patronymic from Martín.
Gómez — A patronymic from the medieval personal name Gome or Gomo. The name is generally regarded as Germanic, but “son of man” based on a resemblance to Latin homo is not a reliable etymology.
García, Rodríguez, González, Fernández, López, Martínez, Sánchez, Pérez, Gómez, and Martín remain among the most frequent surnames in Spain. Their frequency makes it especially important to identify a precise place, parents, and records rather than linking people by surname alone.
