Origin
Meaning and origin of Curulla
The surname CURULLA has its origins in Italy, traced back to the 13th century. It is believed to have derived from the Italian word "curulla," meaning a small hill or mound. The name was initially prevalent in the regions of Tuscany and Umbria, where it is thought to have originated from place names or descriptive surnames referring to people living near small hills or mounds.
One of the earliest recorded instances of the CURULLA surname can be found in a manuscript from the city of Siena, dated 1275. This document mentions a family with the surname CURULLA residing in the area. It is possible that the name may have been associated with a specific location or landmark featuring a small hill or mound.
During the 14th century, the CURULLA surname appeared in various records across central Italy, including the historic city of Florence. Notably, a merchant named Giovanni CURULLA (1320-1392) was documented as a successful trader in silk and spices, contributing to the economic prosperity of the region.
In the 15th century, the name CURULLA gained prominence in the Umbrian town of Spoleto, where a noble family bearing this surname played a significant role in local politics and governance. One of the most prominent members was Francesco CURULLA (1435-1503), who served as a magistrate and advisor to the ruling authorities.
As the centuries progressed, the CURULLA surname spread to other parts of Italy, with notable individuals emerging in different fields. In the 17th century, Antonio CURULLA (1602-1678) was a renowned artist from Naples, known for his intricate frescos and religious paintings adorning several churches in the region.
In the 19th century, the CURULLA surname found its place in the literary world with the birth of the poet and writer, Giulia CURULLA (1835-1905). Her works, which often explored themes of nature and human emotions, gained widespread acclaim during her lifetime.
Despite its Italian origins, the CURULLA surname has also been documented in other European countries, likely due to migration and intermarriage over the centuries. However, the historical roots and earliest recorded instances of this surname can be firmly traced back to the Italian peninsula, particularly in the regions of Tuscany and Umbria.

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.

Keep in mind that these are self-reported numbers.
