Origin
Meaning and origin of Liadis
The surname Liadis is of Greek origin, first appearing in historical records during the Byzantine era. It is believed to have originated from the Greek word "liados," which means "stone" or "rock." This suggests that the name may have been given to someone who lived near a rocky area or worked as a stonemason.
One of the earliest known references to the name Liadis can be found in a manuscript from the 12th century, which mentions a family of that name residing in the town of Thessaloniki. This town, located in modern-day Greece, was a prominent cultural and trade center during the Byzantine period.
In the 14th century, a record from the Venetian archives mentions a merchant named Alexios Liadis, who traded goods between Venice and Constantinople. This indicates that the Liadis family had established themselves as successful traders during that time.
During the Ottoman rule of Greece, the name Liadis continued to be used, although some variations in spelling emerged, such as Liadēs and Liadīs. In the 18th century, a Greek scholar and mathematician named Georgios Liadis (1718-1793) gained recognition for his work in astronomy and navigation.
Another notable figure with the surname Liadis was Konstantinos Liadis (1842-1916), a Greek politician and diplomat who served as the Prime Minister of Greece from 1910 to 1911. He played a significant role in the negotiations leading to the eventual liberation of Crete from Ottoman rule.
In the 20th century, the name Liadis remained relatively uncommon outside of Greece, but there are records of individuals bearing this surname in various parts of the world. For example, Nikolaos Liadis (1901-1978) was a Greek-American architect who designed several notable buildings in New York City, including the Greek Orthodox Archdiocese of America.
While the surname Liadis is not among the most widespread Greek names, it has a rich history that can be traced back to the Byzantine era. The name's connection to the Greek word for "stone" or "rock" has endured through centuries, reflecting the enduring legacy of this family name.

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

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
