Origin
The surname Peraldo originated in Italy, specifically in the regions of Piedmont and Liguria, dating back to the medieval period. It is believed to have derived from the Italian word "peralta," which means "high or elevated place," suggesting that the name may have been associated with people living in elevated or hilly areas.
The earliest recorded instances of the surname Peraldo can be traced back to the 12th and 13th centuries in various historical documents and records from northern Italy. One notable mention is found in the cartulary of the Abbey of San Solutore in Turin, where a certain Guglielmo Peraldo is listed as a landowner in 1219.
In the 14th century, the Peraldo family was well-established in the city of Genoa, where they held significant political and economic influence. Historical records mention several members of the family, including Oberto Peraldo, a merchant and diplomat who served as an ambassador for the Republic of Genoa in the late 1300s.
During the Renaissance period, the surname Peraldo gained further prominence in the maritime republic of Genoa. Antonio Peraldo (1451-1528) was a renowned navigator and explorer who participated in various expeditions to the Americas and the Far East, contributing to the expansion of Genoese trade routes.
Another notable figure with the surname Peraldo was Girolamo Peraldo (1553-1623), a Genoese architect and engineer who designed several prominent buildings in his home city, including the Church of Gesù e Maria and the Palazzo Spinola.
In the 18th century, the Peraldo family established itself in the nearby region of Piedmont, where they became prominent landowners and nobles. Pietro Peraldo (1712-1785) was a respected jurist and legal scholar who served as a judge in the courts of Turin.
Throughout history, the surname Peraldo has been associated with various places and locations, reflecting the family's presence and influence in different regions of northern Italy. For instance, the village of Peraldo in the province of Cuneo, Piedmont, likely derived its name from the family's landholdings in the area.
Demographics
Among Census respondents with the surname Peraldo, the largest self-reported group is White at 79.4%. The next largest groups are Hispanic (16.7%) and Asian/Pacific Islander (2.0%).
The bar chart below shows how Peraldo 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 Peraldo surname at the time of the 2020 Census, not any inherent property of the name itself.
