Origin
Meaning and origin of Dibitetto
The surname DIBITETTO originated in Italy, with its roots tracing back to the medieval period. It is believed to have derived from the Italian phrase "di bittetto," which translates to "from Bittetto." Bittetto was a small village located in the southern region of Puglia, near the city of Bari.
One of the earliest recorded instances of the name can be found in the "Codice Diplomatico Barese," a collection of historical documents from the city of Bari, dating back to the 11th century. The name DIBITETTO appears in several documents, indicating its presence in the region during that time.
In the 13th century, a notable individual named Giacomo DIBITETTO was mentioned in the "Annali di Barletta," a chronicle of the town of Barletta, located near Bari. This reference suggests that the name had spread to neighboring areas within the region.
During the 15th century, the DIBITETTO name was associated with the noble family of the same name, who held landholdings in the town of Bittetto. Records from this period indicate that the family played a significant role in the local governance and economy.
In the 16th century, a renowned physician named Antonio DIBITETTO (1495-1572) gained recognition for his contributions to the field of medicine. He served as the personal physician to several prominent families in Naples and authored several medical treatises that were widely circulated during his lifetime.
Another prominent figure bearing the DIBITETTO surname was Vincenzo DIBITETTO (1620-1698), a Baroque architect who designed several notable churches and palaces in the cities of Naples and Bari. His works, such as the Church of San Francesco di Paola in Naples, are considered significant examples of the Baroque architectural style.
In the 18th century, the DIBITETTO name was associated with a family of landowners and merchants based in the town of Bittetto. Records from this period indicate that they played a crucial role in the local economy and held influential positions within the community.
As the centuries passed, the DIBITETTO surname gradually spread beyond its origins in southern Italy, with individuals bearing the name migrating to other regions and countries. However, the name's deep roots in the town of Bittetto and the surrounding areas of Puglia remain a significant part of its historical legacy.

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