Origin
The surname Testolin has its origins in Italy, specifically in the northern regions of the country. It is believed to have emerged during the late medieval period, around the 13th or 14th century. The name is derived from the Italian word "testa," meaning "head," and is thought to be an occupational surname referring to a person who worked as a maker or seller of helmets or headgear.
Some of the earliest recorded instances of the name can be found in historical documents and records from the regions of Veneto and Lombardy. For example, there is a mention of a Girolamo Testolin in a tax record from the city of Verona, dated 1387. Additionally, the name appears in a legal document from Milan in 1462, referring to a certain Pietro Testolin.
In the 15th century, there are references to a family of Testolins residing in the town of Conegliano, located in the province of Treviso. One notable member of this family was Giovanni Battista Testolin, a respected physician and scholar who lived from 1540 to 1612. He is known for his contributions to the field of medicine and his writings on various medical topics.
Another prominent figure bearing the Testolin surname was Giacomo Testolin, a skilled architect and engineer who lived in the 16th century. He was responsible for the design and construction of several notable buildings and structures in the city of Venice, including the Chiesa di San Moisè and the Palazzo Trevisan.
In the 17th century, the name Testolin can be found in records from the city of Padua, where a family of that name held a respected position within the local nobility. One member, Antonio Testolin (1628-1703), served as a magistrate and played an influential role in the city's governance.
Moving into the 18th century, there are records of a Testolin family residing in the town of Castelfranco Veneto, located in the province of Treviso. One notable member was Francesco Testolin (1748-1824), a successful merchant and landowner who was known for his philanthropic efforts and support of local educational institutions.
Throughout its history, the surname Testolin has also been associated with various place names and locations within the regions of northern Italy. For example, there is a small village called Testolini located in the province of Treviso, which may have derived its name from the presence of families bearing this surname in the area.
Demographics
Among Census respondents with the surname Testolin, the largest self-reported group is White at 91.7%. The next largest groups are Hispanic (4.6%) and Two or More Races (2.8%).
The bar chart below shows how Testolin bearers described their own race and ethnicity on the 2020 Census form. 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 Testolin surname at the time of the 2020 Census, not any inherent property of the name itself.
