Origin
Meaning and origin of Bisordi
The surname Bisordi has its origins in Italy, with records tracing back to the late 15th century. It is believed to have originated from the northern Italian region of Lombardy, particularly in the areas around the city of Milan. The name is derived from the Italian word "bisorda," which refers to a type of rough or coarse fabric.
In the early 16th century, the name Bisordi appears in several historical documents from the city of Milan. One notable mention is in a legal document dated 1512, which lists a merchant named Antonio Bisordi as a witness in a property dispute. This suggests that the name was already established and associated with trade and commerce during that time period.
One of the earliest recorded instances of the name Bisordi can be found in the "Libro d'Oro della Nobiltà Milanese" (Book of Gold of the Milanese Nobility), a historical record of noble families in Milan. The entry dates back to 1578 and mentions a family with the surname Bisordi, indicating their noble status within the city.
In the 17th century, the name Bisordi appears in various church records and baptismal registers from the regions surrounding Milan. One notable example is the birth record of Girolamo Bisordi, born in 1647 in the town of Monza, just north of Milan.
As the name spread throughout Italy, variations in spelling emerged, including Bisorda, Bisorde, and Bissord. These variations were often influenced by local dialects and pronunciation patterns.
Throughout history, several individuals with the surname Bisordi have achieved notable status. One such individual was Giacomo Bisordi, a renowned architect and sculptor who lived in the late 16th century. He is credited with designing several churches and public buildings in Milan and the surrounding areas.
Another notable figure was Giulia Bisordi, a celebrated opera singer from the 18th century. Born in 1705 in Milan, she performed in various cities across Europe and was praised for her exceptional vocal talents.
In the 19th century, Pietro Bisordi, born in 1821, was a prominent lawyer and politician in Milan. He served as a member of the city council and was actively involved in promoting social and legal reforms.
Toward the end of the 19th century, the name Bisordi gained recognition in the field of literature. Alfredo Bisordi, born in 1868 in Pavia, was a respected poet and author, known for his works celebrating the beauty of the Italian countryside.
In the 20th century, the Bisordi name continued to be associated with artistic and intellectual pursuits. Elena Bisordi, born in 1912 in Milan, was a highly acclaimed painter whose works were exhibited in galleries across Italy and Europe.
While the surname Bisordi has its roots in northern Italy, particularly in the Lombardy region, it has since spread to other parts of the country and beyond, with individuals carrying this name making their mark in various fields throughout history.

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.

Keep in mind that these are self-reported numbers.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
