Origin
The surname "Spilios" is of Greek origin, with its roots tracing back to the Byzantine era in the 9th-12th centuries AD. It is derived from the Greek word "spelios," which translates to "cave" or "grotto." This suggests that the name may have originated from individuals who lived in or near caves, or from a specific geographic location associated with caves.
One of the earliest recorded instances of the name "Spilios" can be found in a Greek manuscript from the 11th century, which mentions a certain "Theodosius Spilios" as a landowner in the region of Thessaly. This provides evidence of the surname's existence during the Byzantine period.
In the 14th century, a notable figure named "Manuel Spilios" was a prominent scholar and writer who contributed to the preservation of ancient Greek literature. He is believed to have been born around 1320 in Constantinople (modern-day Istanbul) and played a significant role in the intellectual circles of the Byzantine Empire.
During the Ottoman rule in Greece, which lasted from the 15th to the 19th century, the surname "Spilios" continued to be used. A notable example from this period is "Georgios Spilios," a merchant and shipowner who lived in the 18th century on the island of Chios. His business dealings and maritime activities contributed to the island's economic prosperity.
In the 19th century, "Alexandros Spilios" was a Greek revolutionary who fought against the Ottoman Empire during the Greek War of Independence (1821-1829). He was born in 1790 in the village of Megalochori, in the Peloponnese region, and played a crucial role in the liberation of his homeland.
Another notable figure from the same era was "Konstantinos Spilios," a Greek politician and diplomat who served as the Minister of Foreign Affairs for the Kingdom of Greece in the late 19th century. He was born in 1844 on the island of Hydra and played a significant role in shaping Greece's foreign policy during a critical period in the country's history.
These examples illustrate the long-standing presence of the surname "Spilios" in Greek history, spanning from the Byzantine era to the modern era, and its association with various notable individuals across different fields, including scholarship, trade, revolutionary movements, and politics.
Demographics
Among Census respondents with the surname Spilios, the largest self-reported group is White at 92.2%. The next largest groups are Hispanic (5.2%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Spilios 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 Spilios surname at the time of the 2020 Census, not any inherent property of the name itself.
