Origin
Meaning and origin of Loyko
The surname "LOYKO" is of Ukrainian origin, with its roots dating back to the 15th century. It is believed to have originated in the western regions of Ukraine, particularly in the areas around the city of Lviv.
The name "LOYKO" is derived from the Ukrainian word "loy," which means "clay" or "loam." This suggests that the name may have been initially associated with individuals who worked with clay or were involved in pottery-making or brick-making professions.
One of the earliest recorded instances of the name "LOYKO" can be found in the Lviv City Archives, where a merchant named Petro LOYKO was mentioned in a document dated 1472. This suggests that the name had already gained recognition in the region by the late 15th century.
In the 16th century, the name "LOYKO" appeared in several church records and land registers in the regions around Lviv and Ternopil. A notable example is Ivan LOYKO, a landowner who was recorded in the Ternopil County Registry in 1587.
During the 17th century, the name "LOYKO" began to spread beyond western Ukraine. In 1634, a priest named Hryhoriy LOYKO was documented in the archives of the Kyiv Pechersk Lavra, one of the most important monasteries in Eastern Europe.
One of the most prominent individuals with the surname "LOYKO" was Yuriy LOYKO (1700-1779), a prominent Ukrainian philosopher and theologian who taught at the Kyiv-Mohyla Academy. He made significant contributions to the fields of ethics and metaphysics.
Another notable figure was Marko LOYKO (1832-1897), a Ukrainian painter and illustrator who was part of the Kharkiv School of Painting. His works often depicted scenes from Ukrainian village life and captured the beauty of the Ukrainian countryside.
In the 19th century, the name "LOYKO" also gained recognition in the world of literature. Oleksandr LOYKO (1856-1918) was a Ukrainian writer and poet who was part of the "Kharkiv Romantic School" literary movement.
Towards the end of the 19th century and into the early 20th century, the name "LOYKO" became more widely dispersed throughout Ukraine and beyond. Mykola LOYKO (1878-1942) was a prominent Ukrainian economist and statesman who served as the Minister of Finance in the Ukrainian People's Republic during the turbulent years following the Russian Revolution.
Overall, the surname "LOYKO" has a rich historical heritage, deeply rooted in the cultural and geographical landscape of Ukraine. While its origins can be traced back to the 15th century, the name has left an indelible mark across various fields, from academia and literature to art and politics, over the course of several centuries.

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 Loyko 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.
