Origin
The surname Belardinelli originates from Italy, with its earliest records dating back to the 12th century. It is believed to have originated in the region of Emilia-Romagna, particularly in the city of Bologna. The name is derived from the Italian word "belardo," which means "beautiful" or "handsome," combined with the diminutive suffix "-elli," suggesting it was initially used as a nickname or a descriptive name for an individual with attractive features.
In the 13th century, the name Belardinelli appeared in several historical documents, including the Codice Diplomatico Bolognese, a collection of medieval manuscripts from Bologna. One of the earliest recorded instances of the name was in 1235, when a certain Guido Belardinelli was mentioned as a witness in a legal document.
During the Renaissance period, the Belardinelli family gained prominence in Bologna, with several members holding influential positions in the city's government and cultural circles. Notably, Giacomo Belardinelli (1490-1560) was a renowned humanist scholar and poet who served as a professor at the University of Bologna.
Another notable figure was Giovanni Belardinelli (1572-1637), a talented painter from Bologna who specialized in religious artwork. His works can be found in various churches and museums across Italy, including the Basilica of San Petronio in Bologna.
In the 18th century, the Belardinelli name appeared in the historic records of the Papal States, particularly in the region of Marche. Francesco Belardinelli (1715-1790) was a prominent lawyer and legal scholar from Macerata, known for his contributions to the field of canon law.
As the surname spread throughout Italy, it also gave rise to variations such as Belardini and Belardino. One notable bearer of the latter variant was Girolamo Belardino (1592-1655), a Jesuit priest and missionary who played a significant role in the evangelization efforts in South America.
Over the centuries, the Belardinelli family has produced numerous individuals who have left their mark in various fields, from academia and the arts to law and religion. While the name may have evolved in spelling and pronunciation across different regions, its origins remain firmly rooted in the rich cultural heritage of Italy.
Demographics
Among Census respondents with the surname Belardinelli, the largest self-reported group is White at 86.2%. The next largest groups are Hispanic (9.5%) and Two or More Races (3.4%).
The bar chart below shows how Belardinelli 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 Belardinelli surname at the time of the 2020 Census, not any inherent property of the name itself.
