Origin
The surname Ragaglia has its origins in Italy, specifically in the northern regions of Piedmont and Lombardy. It is believed to have emerged during the 12th or 13th century, derived from the Italian word "ragaglia," which referred to a type of coarse woolen fabric used for making cloaks or capes.
One of the earliest recorded instances of the name Ragaglia can be found in a census record from the town of Cuneo, Piedmont, dated 1387. This document lists a certain Pietro Ragaglia, who was likely a weaver or merchant involved in the production or trade of this particular fabric.
In the 15th century, the name appeared in several legal documents and property records from the city of Milan, suggesting that the Ragaglia family had established a presence in this important center of commerce and industry. One notable individual from this period was Giovanni Battista Ragaglia, a wealthy silk merchant born in 1472, who played a significant role in shaping the city's thriving textile trade.
As the name spread throughout northern Italy, it adopted various spellings and regional variations, such as Ragaglio, Ragagli, and Ragagia. Some of these variations can be traced back to historical records from cities like Genoa, Turin, and Bergamo.
In the 16th century, a branch of the Ragaglia family migrated to the island of Sardinia, where they became influential landowners and vineyard proprietors. One of the most prominent figures from this era was Francesca Ragaglia (1525-1599), who was renowned for her philanthropic efforts and the establishment of a charitable foundation that supported underprivileged families in the region.
The 17th century saw the emergence of several notable scholars and intellectuals bearing the Ragaglia name, including the philosopher and theologian Antonio Ragaglia (1613-1678), whose works on metaphysics and epistemology were widely studied in academic circles across Europe.
Throughout the 18th and 19th centuries, the Ragaglia surname continued to be associated with various professions and trades, from artisans and craftsmen to merchants and entrepreneurs. One noteworthy individual from this period was Luigi Ragaglia (1789-1863), a renowned architect who designed several landmark buildings in the city of Turin, including the iconic Palazzo Carignano.
While the surname Ragaglia has its roots in northern Italy, it eventually spread to other regions and countries due to migration and diaspora. Today, individuals bearing this name can be found across Italy and in other parts of the world, carrying on the rich historical legacy and traditions associated with this distinctive Italian surname.
Demographics

The bar chart below shows how Ragaglia bearers described their own race and ethnicity on the 2020 Census form. 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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Ragaglia surname at the time of the 2020 Census, not any inherent property of the name itself.
