Origin
The surname BONCORE is believed to have originated in Italy during the Middle Ages. It is derived from the Italian words "buon" meaning "good" and "core" meaning "heart", suggesting that the name may have been given to someone with a kind or generous nature.
One of the earliest recorded instances of the name BONCORE can be found in a manuscript from the city of Siena, dated to the 13th century. This document mentions a merchant named Giovanni BONCORE, who was involved in the wool trade.
In the 14th century, a noble family by the name of BONCORE resided in the region of Tuscany. Records indicate that they owned land and vineyards in the area around the town of San Gimignano. One notable member of this family was Filippo BONCORE, who served as a city councilor in San Gimignano in the year 1375.
During the Renaissance period, the name BONCORE became associated with the arts. In the 16th century, a painter named Luca BONCORE was known for his frescoes in churches throughout Florence and the surrounding areas. His most famous work is a series of biblical scenes adorning the interior of the Basilica di Santa Croce.
In the 17th century, a writer and philosopher named Antonio BONCORE gained recognition for his treatises on ethics and morality. He was born in Naples in 1602 and spent much of his life teaching at universities in Italy and France.
Another notable figure with the surname BONCORE was Giulia BONCORE, a poet who lived in Venice during the 18th century. Her collection of sonnets and love poems, titled "Il Cuore Ardente" (The Burning Heart), was widely acclaimed and published in multiple editions throughout Europe.
While the name BONCORE has its roots in Italy, it has since spread to other parts of the world through immigration and diaspora communities. However, the rich history and origins of this surname can be traced back to the medieval and Renaissance periods in Italy, where it was associated with merchants, nobility, artists, and intellectuals.
Demographics
Among Census respondents with the surname Boncore, the largest self-reported group is White at 94.1%. The next largest groups are Hispanic (3.0%) and Two or More Races (2.4%).
The bar chart below shows how Boncore 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 Boncore surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
