Origin
Meaning and origin of Giumarra
The surname GIUMARRA has its origins in Italy, traced back to the 15th century. The name is derived from the Italian word "giumarro," meaning a type of hazelnut tree. It is believed to have originated in the regions of Calabria and Sicily, where hazelnut cultivation was prevalent.
In ancient records, the name can be found spelled in various ways, such as Giumarra, Giumarro, and Giumaro. One of the earliest recorded mentions of the name appears in the Sicilian archives from the late 1400s, where a landowner named Antonino Giumarra is listed as owning a hazelnut orchard.
The Giumarra family played a significant role in the agricultural and trade sectors of southern Italy during the Renaissance period. Historical documents mention a prominent merchant named Giuseppe Giumarra, born in 1522, who established trade routes for exporting hazelnuts and other agricultural products to other parts of Europe.
In the 17th century, a notable figure named Antonio Giumarra (1634-1702) was a renowned botanist and horticulturist from Calabria. He authored several influential works on plant cultivation, including "Treatise on Hazelnut Cultivation" published in 1675.
Another notable individual with the surname GIUMARRA was Vincenzo Giumarra (1788-1864), a Sicilian politician and landowner who played a crucial role in the Italian unification movement during the Risorgimento period.
During the 19th century, many Italians, including those with the surname GIUMARRA, immigrated to the United States and other parts of the world. One of the earliest recorded instances of the name in America was Sebastiano Giumarra, who arrived in New York from Sicily in 1875.
Throughout history, the surname GIUMARRA has been associated with agricultural traditions, particularly hazelnut cultivation, in the regions of southern Italy. Despite its relative rarity, the name has left a notable mark in various fields, from horticulture and trade to politics and immigration.

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.
