Origin
Meaning and origin of Dearagon
The surname DEARAGON originated in the Aragon region of Spain during the medieval period. It is derived from the Spanish phrase "de Aragon," which means "from Aragon." This suggests that the earliest bearers of this surname likely came from or had some connection to the historical kingdom of Aragon.
One of the earliest recorded instances of the DEARAGON surname can be found in the 14th century Catalan manuscript "Llibre de Fets" (Book of Deeds), which chronicles the life of King James I of Aragon. The manuscript mentions a knight named Pedro DEARAGON who fought alongside the king during the Reconquista.
In the 15th century, a nobleman named Juan DEARAGON is recorded as owning lands in the town of Calatayud, located in the province of Zaragoza, Aragon. This suggests that the DEARAGON family had established itself as part of the local nobility in the region.
During the 16th century, a renowned Spanish poet and playwright, Lope de Vega, wrote a play titled "El Marques de las Navas," which featured a character named Gonzalo DEARAGON. This literary reference further solidifies the surname's association with the region of Aragon.
In the 17th century, a famous Spanish painter, Diego Velázquez, painted a portrait of a man named Gaspar DEARAGON. The portrait is currently housed in the Prado Museum in Madrid, Spain.
Another notable bearer of the DEARAGON surname was a Spanish explorer named Pedro DEARAGON, who accompanied the famous conquistador Hernán Cortés on his expedition to Mexico in the early 16th century. Pedro DEARAGON is credited with being one of the first Europeans to set foot in what is now modern-day Mexico City.
While the DEARAGON surname has its roots in the Aragon region of Spain, it has since spread to other parts of the world through migration and intermarriage. However, its origins can be traced back to the medieval period in the historical kingdom of Aragon, where it was borne by nobility, artists, and explorers.

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.
