Marquez surname meaning

Marquez is the unaccented US spelling of Márquez, a Spanish patronymic meaning “son of Marco” or “son of Marcos.” The -ez ending marks descent from a personal-name ancestor, while Marco and Marcos are Romance forms of the biblical and Latin name Marcus. Marques is a neighboring Portuguese or Galician form, and accents are frequently omitted in American records. Different families could form Márquez independently in Iberian communities, so the surname does not prove one founder. Parent’s name is the high-confidence catalog type. The older history of Marcus is background, not a separate surname-level translation.
