Origin
Meaning and origin of Delarea
The surname DELAREA is believed to have originated in the region of Catalonia, Spain during the late 15th century. It is derived from the Spanish words "de la" meaning "of the" and "area" meaning "area" or "region". This suggests the name may have originated as a descriptive term for someone who lived in a particular area or region.
One of the earliest recorded instances of the DELAREA surname can be found in a document from the Archdiocese of Barcelona dated 1497, which mentions a Juan Delarea, a landowner in the village of Sitges. The name also appears in several other church records from the 16th and 17th centuries in various spellings such as "De la Rea", "De la Reya", and "Delarea".
In the late 16th century, the DELAREA surname began to spread beyond Catalonia as families migrated to other parts of Spain and its colonies in the Americas. One notable individual was Pedro Delarea, a Spanish explorer who accompanied Hernán Cortés on his expedition to conquer Mexico in 1519. He later settled in the region known as Nueva España (present-day Mexico) and was granted land by the Spanish Crown.
During the 17th and 18th centuries, the DELAREA surname can be found in various records and documents from different parts of Spain, including Andalusia, Valencia, and the Balearic Islands. One prominent figure was Juana Delarea, a wealthy landowner from Seville who donated a significant portion of her estate to the construction of a local church in 1673.
In the 19th century, individuals bearing the DELAREA surname began to migrate to other parts of the world, including Latin America and the United States. One notable figure was Miguel Delarea, a Cuban writer and poet born in Havana in 1825. He is best known for his collection of poems titled "Cantos de la Patria" (Songs of the Homeland), which celebrated Cuban culture and identity.
Another significant figure was José Delarea, a Spanish businessman and philanthropist who lived in Buenos Aires, Argentina in the late 19th century. He made his fortune in the cattle trade and used his wealth to establish several schools and hospitals in the region.

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.

Keep in mind that these are self-reported numbers.
