The history of the last name Urdialez

The surname URDIALEZ originated in the Basque region of northern Spain and southwestern France, likely emerging in the late medieval period around the 13th or 14th century. It is derived from the Basque words "urdi," meaning "pig," and "alez," meaning "valley" or "ravine." Therefore, the name likely referred to someone who lived or worked in a valley associated with the raising or herding of pigs.

One of the earliest known records of the name appears in a 1487 census of the town of Hernani, located in the Basque province of Gipuzkoa, Spain. The entry lists a Juan de Urdialez as a resident of the town. In the 16th century, a document from the Basque town of Azpeitia mentions a Martin Urdialez, who was involved in a legal dispute over land ownership.

The name has also been found in historical records from the neighboring regions of Navarre and La Rioja, suggesting that individuals with this surname may have migrated or established branches in these areas as well. For example, a 1602 baptismal record from the town of Viana, in Navarre, lists the birth of a child named Maria Urdialez.

Variations in the spelling of the surname have been noted over time, including Urdialiez, Urdiález, and Urdializgoitia. These variations may have arisen due to regional dialects, scribal errors, or the adoption of additional locative suffixes to distinguish different family branches.

One notable individual bearing this surname was Juan Ignacio de Urdialez y Villarreal (1711-1787), a Spanish naval officer and explorer who participated in several expeditions to the Pacific Northwest coast of North America in the latter half of the 18th century. Another figure was Mariano Urdialez (1842-1923), a Spanish lawyer and politician who served as a deputy in the Spanish Congress during the late 19th century.

Other individuals with the surname URDIALEZ include Pedro Urdialez (1654-1721), a Basque merchant and landowner mentioned in historical records from the town of Tolosa, and Catalina Urdialez (1789-1865), a Basque woman noted in local histories for her philanthropic work in the village of Azkoitia.
