Origin
Meaning and origin of Gattozzi
The surname Gattozzi is of Italian origin, with roots dating back to the late medieval period in the region of Tuscany. It is believed to be derived from the Italian word "gatto," meaning "cat," suggesting an occupational or descriptive origin for the name.
One of the earliest known references to the Gattozzi name can be found in a 14th-century manuscript from the city of Florence, where a certain Giovanni Gattozzi was recorded as a merchant and landowner. This indicates that the name had already established itself among the urban elite of the time.
In the 15th century, the Gattozzi family gained prominence in the town of Certaldo, near Florence. Records from this era mention a Tommaso Gattozzi, who served as a respected magistrate and played a role in local governance.
The name Gattozzi is also linked to the historic town of Montepulciano, located in the Tuscan province of Siena. Here, the Gattozzi family had a long-standing presence, with some members holding significant positions within the local nobility and ecclesiastical hierarchy.
One notable figure bearing the Gattozzi name was Bernardo Gattozzi (1452-1517), a Renaissance scholar and humanist who hailed from Montepulciano. He was renowned for his contributions to the study of classical literature and his patronage of the arts.
Another prominent individual was Vincenzo Gattozzi (1589-1662), a Jesuit priest and theologian from Florence. He authored several influential works on religious subjects and served as a prominent figure within the Catholic Church during the 17th century.
In the 18th century, the Gattozzi family continued to hold a respected position in Tuscan society. Francesco Gattozzi (1720-1795), a nobleman from Montepulciano, was known for his philanthropic endeavors and support for local institutions.
While the Gattozzi surname has its roots firmly planted in the Tuscan region, over the centuries, it has spread to other parts of Italy and beyond, carried by individuals and families who migrated to new areas. Today, the name remains most prevalent in its historic homeland but can also be found among Italian communities around the world.

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.
