Most authors are agreed that this is a surname of Aragon, specifically the town of Ejea de los Caballeros (Zaragoza).
This town was founded by the Romans and known Egara, which, undoubtedly, was formed in Ejea. In 1108, King Alfonso I of Aragon conquered, wrested from the Moors and calling Ejea then was added to the name "of the Caballeros" by having village of principal gentlemen of his army.

It is here in the reference made to "principal gentlemen" where you can find the origin of the surname Navarro because, according to some authors, that source came from a nickname or alias. Among the gentlemen were cited several natives of Navarra, as they were known as "Navarre". It is known by the name of one of them, Sancho Garcia who was among those who settled in this village of Ejea de los Caballeros. It is possible that in the early days was known as "the Navarre" and that, ultimately, what added to his name, making last name. This is not surprising, however, was quite natural in the Middle Ages. Either he added the nickname as a surname or took the place of conquest. An example of this we have in the name Carrion, who was taken for such by those who conquered the town of Carrion and being Condes, this village became Carrión de los Condes.

Therefore, the version, that being the surname Navarro of Aragonese origin, is absolutely correct, as it was in a village in Aragon, where he filed his original site and the trunk from where they departed the various branches that were spreading across Peninsula, and this does not contradict at all, the hypothesis that the early adopters of this nature were navarra name.

That from the beginning, the Navarro surname was of great nobility no doubt. Apart from its mention was made before the "gentlemen very core", there are data that bear witness to this: In 1695, the Chief Justice of Aragon gave the Cortes signature of infanzonía possessory and nobility in favor of Navarre established Ejea de los Caballeros (use the J to name this place, it is not necessary as the time at which we mean that is how appointed. At a later period was changed to G to J, making Egea de los Caballeros ).

The infanzonía of Navarro born in this village was confirmed by the Chief Justice of Aragon, on the grounds that they were descendants of Miguel Navarro, who married Dona Maria de Burrea.

In this family proceeded Ignacio Navarro, a resident of Pamplona, which proved his nobility in the Royal Chancery of Pamplona, 22 December 1779. As shown, this is a character named Navarro and, moreover, is born precisely in Navarre. This detail can confirm what was said at the beginning of the origin of the name, which, while Aragon, in principle, ie in its trunk, was a native of Navarre.

Other Navarro also proved his nobility, among them, as the nobleman, Don Manuel Rafael Navarro neighbor and registered in the town of Uncastillo belonging Ejea ai judicial district of the Knights.

Knights of the name they were, Don Ignacio and Javier Navarro Marco nobility who tried to join the Brotherhood of Nuestra Senora del Portillo, Zaragoza and Juan Jose Navarro was created Marquess of Victoria, on May 7, 1744.

The list of members who proved his nobility and purity of blood to the orders of Santiago, Calatrava, Montesa, Carlos III and Royal Company of Midshipmen, is extensive sample what the nobility of the Navarro. In the Royal Chancery of Valladolid were also submitted numerous requests in this regard.

Navarro surnamed were many who devoted their activities to the profession of arms. Leaving aside those who participated in the Reconquista, in later centuries many of them were distinguished by the courage shown in many military actions took part. Suffice it to cite a single example: Pedro Navarro, born in 1460, was a military engineer who specialized in the implementation of mines in the siege of fortresses. He actively participated in campaigns in Italy and was lieutenant of Cisneros in the African expedition that culminated in the conquest of Oran. In the war of the Holy League against the French, was taken prisoner at Ravenna (1512) and King Francis I of France, aware of the value and intelligence of Navarro suggested he enter his service, which was accepted. Thus, Peter Navarro is excelled in Milan and in making the battles of Marignano and Bicocca.
Around the same time, but dedicated to an activity quite different lived another Navarro, Juan, born in Marchena, in 1525, who became famous as a composer. He was Master of the Chapel in Avila, Salamanca, Ciudad Rodrigo and Palencia.
In the field of politics the Navarro surname has also been highlighted much: Juan Navarro Reverter, (1844-1924) Chancellor of the Exchequer for the Conservative Party of Canovas del Castillo, though he died later and was again Prime Minister, but now by the Liberal Party, which was passed by not accepting the leadership of the Conservative Party by Samuels. Rodrigo Carlos Navarro, also a politician, who collaborated with General O'Donnell during the Liberal Union and became part of the Revolutionary Council which was convened in Madrid after the Revolution of 1868. Member of Parliament, was then minister of development in the governments formed by Sagasta.
