Origin
Meaning and origin of Gianaris
The surname Gianaris originated in Greece, specifically in the regions of Athens and the surrounding Attica region. It is believed to have emerged during the Byzantine period, between the 4th and 15th centuries AD. The name is derived from the Greek personal name "Giannis," a variant of the name "Ioannis," which is the Greek form of the name John.
One of the earliest recorded references to the Gianaris surname can be found in the archives of the Monastery of Daphni, located near Athens. These records date back to the 14th century and mention individuals with the surname Gianaris as residents of the nearby village of Haidari.
During the Ottoman rule of Greece, which lasted from the 15th to the 19th century, the Gianaris surname was common among Greek families living in the Attica region. Several historical documents from this period, such as tax records and property deeds, contain references to individuals bearing the Gianaris name.
In the 19th century, as the Greek War of Independence unfolded, several Gianaris family members were noted for their participation in the struggle against Ottoman rule. One notable figure was Georgios Gianaris (1798-1867), a military officer who fought in several battles and later served as a member of the Greek Parliament.
Another prominent individual with the Gianaris surname was Konstantinos Gianaris (1854-1921), a lawyer and politician who served as the Mayor of Athens from 1899 to 1905. During his tenure, he oversaw significant infrastructure projects and worked to modernize the city.
In the 20th century, the Gianaris surname continued to be well-represented in various fields. Ioannis Gianaris (1901-1985) was a renowned Greek linguist and philologist, known for his contributions to the study of the Greek language and its dialects.
Stefanos Gianaris (1924-2007) was a successful Greek businessman and philanthropist, who founded several companies and supported various charitable organizations in Greece and abroad.
Over time, the Gianaris surname has spread beyond Greece, with individuals bearing this name found in various parts of the world, including the United States, Australia, and several European countries. However, the name's origins can be traced back to the Greek regions of Athens and Attica, where it has a long and rich history.

The bar chart below shows how Gianaris 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 Gianaris surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
