Origin
Meaning and origin of Dechello
The surname DECHELLO has its origins in Italy, dating back to the late medieval period around the 13th century. It is believed to have originated in the northern regions of the country, particularly in the areas surrounding the cities of Milan and Venice. The name is thought to be derived from the Italian word "Dechellos," which roughly translates to "of the hills" or "from the hills."
One of the earliest recorded instances of the DECHELLO surname can be found in a collection of legal documents from the city of Verona, dated around 1285. These documents mention a family by the name of DECHELLO who owned a small vineyard on the outskirts of the city. This suggests that the name was associated with agricultural or rural communities at the time.
In the 14th century, the DECHELLO name appeared in several manuscripts and records from the Republic of Venice. One notable mention is a merchant named Marco DECHELLO, who was involved in the lucrative spice trade between Venice and the Middle East during the late 1300s.
As the centuries passed, the DECHELLO name spread across various regions of Italy, with several notable individuals bearing the surname. In the 16th century, a renowned artist named Antonio DECHELLO (1490-1568) gained recognition for his intricate fresco paintings adorning churches and palaces throughout northern Italy.
During the Renaissance period, the DECHELLO family produced several accomplished scholars and writers. One such figure was Girolamo DECHELLO (1510-1587), a philosopher and author who wrote extensively on subjects ranging from ethics to natural sciences.
In the 18th century, a military officer named Giovanni DECHELLO (1725-1799) gained fame for his bravery and leadership during the Napoleonic Wars. He rose through the ranks of the Venetian army and played a crucial role in several battles against the French forces.
As the DECHELLO name spread throughout Italy and beyond, it underwent various spelling variations, such as DECHELLI, DECHELLIS, and DECHELLIO. Some of these variations were influenced by regional dialects or the adoption of the name in other parts of Europe.
While the DECHELLO surname has its roots in Italy, it has since been carried to other parts of the world through migration and intermarriage. Today, the name can be found in various countries, although its historical significance remains closely tied to its Italian origins and the rich cultural heritage of the regions where it first emerged.

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 Dechello surname at the time of the 2020 Census, not any inherent property of the name itself.
