Origin
Meaning and origin of Deperi
The surname DEPERI has its roots in the Italian region of Tuscany, dating back to the 14th century. It is derived from the Latin word "de" meaning "from" and the Italian word "peri" meaning "pear trees," suggesting that the name may have originated from a place or area known for its abundance of pear orchards.
One of the earliest recorded instances of the DEPERI surname can be found in a land registry from the town of San Gimignano in Tuscany, dated 1376. This document mentions a certain Guido DEPERI as a landowner in the region. Additionally, the name appears in several other medieval documents from various Tuscan towns, such as Siena and Florence, indicating its widespread presence in the area during that time.
In the 15th century, a notable figure bearing the DEPERI surname was Bartolomeo DEPERI, a renowned sculptor and artist from Siena. He was commissioned to create several works of art for the city's cathedral and other prominent buildings, showcasing his remarkable talent and contributing to the rich artistic heritage of the region.
Moving forward to the 16th century, the DEPERI name gained further prominence with the birth of Giovanni DEPERI in 1524. Giovanni was a respected scholar and philosopher who made significant contributions to the intellectual discourse of his time. His writings on ethics and metaphysics were widely studied and debated in academic circles throughout Italy.
Another individual of note was Lucrezia DEPERI, born in 1587 in the city of Pisa. She was a celebrated poet and writer whose works explored themes of love, nature, and the human condition. Lucrezia's poetry was highly regarded during her lifetime and continues to be studied and appreciated by scholars of Italian literature.
In the 18th century, the DEPERI surname gained further prominence with the birth of Tommaso DEPERI in 1712 in Florence. Tommaso was a renowned architect who played a pivotal role in the design and construction of several prominent buildings in the city, including the Basilica di Santa Croce and the Palazzo Pitti. His innovative architectural styles and attention to detail left a lasting impact on the cityscape of Florence.
Throughout its history, the DEPERI surname has been associated with various professions, from artists and scholars to landowners and professionals. While its origins can be traced back to the pear orchards of Tuscany, the name has spread across Italy and beyond, carrying with it a rich cultural heritage and a testament to the diverse contributions of its bearers.

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.
