Show ContentsMuniz History, Family Crest & Coats of Arms

The mountainous borders of Spain contain the origins of the prestigious surname Muniz. The earliest forms of hereditary surnames in Spain were the patronymic surnames, which are derived from the father's given name, and metronymic surnames, which are derived from the mother's given name. In this case, the surname is derived from the first-name Mummius. Thus, the surname Muniz simply signifies "son of Mummius". The first-name Mummius is itself derived from the name of a Roman tribe whose most famous member was Mummius Achaicus, the Roman Consul who destroyed Corinth in the year 146. The "oz" or "ez" ending to the surname is indicative of its patronymic origins.

Early Origins of the Muniz family

The surname Muniz was first found in Galicia and Castile, important Christian kingdoms of medieval Spain.

The family "claim descent according to some writers, of the Roman consul Lucio Murio; according to others, from the Royal House of Scotland, and there are still those who consider him a descendant of Count Munon Rodriguez, who lived in the 750s." 1

The family proved their nobility at various times, in the Orders of Santiago, Calatrava, Alcantara, Carlos III and San Juan de Jerusalem; in the Royal Chanceries of Valladolid and Granada, and in the Royal Company of Marine Guards. 1

In Andalucia, Munoz de Loaysa rose to the nobility in the Order of Santiago in 1720 and in Rojas, Munoz of San Pedro, originally from Viniegra de Arriba (Logrono), proved his nobility in the Royal Chanceries of Valladolid and Granada and in the Order of Alcantara. Don Tomas Munoz de San Pedro y Montenegro was created Viscount of Torre Hidalgo and Baron de Campo de Aguilas in 1837. Dona Micaela Munoz de San Pedro y Flores de Lizaur was created Countess of San Miguel in 1876. 1
