Origin
Meaning and origin of Curup
The surname Curup is believed to have originated in the Iberian Peninsula, specifically in the region of Catalonia, Spain, during the medieval period. It is thought to derive from the Catalan word "currup," meaning "ravine" or "gully," suggesting that the name may have initially referred to someone who lived near such a geographical feature.
One of the earliest recorded instances of the name can be found in the Català-Valencià region of Spain, dating back to the 13th century. The name appears in various historical documents, including land records and tax registers, indicating that individuals bearing the surname were present in the area during that time.
In the 14th century, the name Curup was documented in the town of Lleida, where a certain Bernat Curup was listed as a landowner in the year 1347. This record provides insight into the presence of the surname in the region during that era.
During the 15th century, the name gained prominence in the region of Valencia, where a notable figure named Jaume Curup was a respected merchant and landowner. He was born in 1429 and played a significant role in the local economy and politics of the time.
In the 16th century, the Curup surname spread to other parts of Spain, as well as to the Spanish colonies in the Americas. One notable individual from this period was Hernán Curup, a Spanish conquistador who participated in the conquest of Peru alongside Francisco Pizarro. He was born in 1505 and played a crucial role in the subjugation of the Inca Empire.
Another significant figure was Margarida Curup, a Catalan noblewoman born in 1562. She was renowned for her philanthropic efforts and her support of the arts and literature in Barcelona during the Renaissance period.
In the 17th century, the Curup surname made its way to the New World, with several individuals bearing the name settling in various Spanish colonies. One such individual was Juan Curup, who was born in 1621 and became a prominent landowner and cattle rancher in the region of present-day Argentina.
Throughout the following centuries, the surname Curup continued to appear in various historical records across Spain and its former colonies, indicating the enduring presence of individuals bearing this name in various parts of the world.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. 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.
