Origin
Meaning and origin of Valdellon
The surname Valdellon is of Spanish origin and can be traced back to the medieval period. It derives from the Spanish words "valle" meaning valley and "león" meaning lion, suggesting that the name originated from a valley or region associated with lions or a lion-like symbol.
The earliest recorded instances of the Valdellon surname can be found in ancient Spanish manuscripts and records from the 13th and 14th centuries. These early references often mention individuals or families residing in or hailing from specific valleys or regions within Spain, particularly in the northern regions like Castile and Leon.
One notable historical figure bearing the Valdellon surname was Rodrigo Valdellon, a prominent Spanish military commander who served under King Alfonso XI of Castile in the 14th century. He played a crucial role in the Reconquista, the centuries-long campaign to reclaim the Iberian Peninsula from Moorish rule.
During the 15th century, the Valdellon name appeared in various municipal records and charters from the region of Aragon, indicating the presence of families or individuals with this surname in that area. One such record from 1487 mentions a Juan Valdellon, a local landowner and prominent citizen in the town of Teruel.
In the 16th century, the Valdellon surname gained further prominence with the birth of Diego Valdellon y Mendoza (1505-1572), a renowned Spanish jurist and scholar who served as a judge in the Royal Chancery of Granada. His legal writings and treatises on Spanish law were widely influential during that era.
Another noteworthy figure was María Valdellon (1620-1692), a celebrated Spanish painter and portraitist from Seville. Her works, which often depicted religious scenes and portraits of nobility, can be found in several museums and churches across Spain.
Throughout the centuries, the Valdellon surname has been associated with various place names and regions within Spain, such as Valdellon de Torío in the province of León, Valdellon de Arriba in the province of Palencia, and Valdellon de Abajo in the province of Burgos. These place names likely originated from the physical geography of the area or the presence of notable Valdellon families in those locations.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
