Origin
Meaning and origin of Giustra
The surname Giustra originated in Italy, specifically in the region of Lombardy, during the medieval period. It is believed to be derived from the Italian word "giusto," meaning "just" or "righteous." This suggests that the name may have been initially bestowed upon someone who was known for their sense of fairness or moral uprightness.
The earliest recorded instances of the surname Giustra can be traced back to the 13th century. One notable example is found in the archives of the city of Milan, where a certain "Guglielmo Giustra" is mentioned in a document dated 1274. This suggests that the name was already well-established in the region at that time.
Throughout the centuries, the Giustra name has been associated with various notable individuals. In the 15th century, a Venetian merchant named Marco Giustra gained prominence for his successful trading ventures in the Mediterranean region. He was born in 1422 and died in 1489.
Another notable figure bearing the Giustra surname was Girolamo Giustra, a 16th-century Italian architect and sculptor who was active in the cities of Genoa and Milan. He was born in 1522 and is renowned for his work on several churches and public buildings in those cities.
In the 17th century, the Giustra family produced a distinguished member in the form of Filippo Giustra, a renowned jurist and legal scholar. He was born in 1634 and authored several influential treatises on Roman law, which were widely studied throughout Europe at the time.
Moving into the 18th century, we encounter Giovanni Battista Giustra, a celebrated Italian painter who specialized in portraiture and religious scenes. He was born in 1718 and his works can still be admired in various churches and galleries across Italy.
The name Giustra has also been associated with various place names and locations throughout Italy. For instance, there is a small village in the province of Bergamo called "Giustra," which likely derived its name from the surname itself or vice versa.
While the surname Giustra has its roots in Italy, it has since spread to other parts of the world due to migration and diaspora. However, the historical records and notable figures mentioned above provide a glimpse into the rich heritage and significance of this surname within the Italian cultural landscape.

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