Origin
Meaning and origin of Kiousis
The surname KIOUSIS is of Greek origin, tracing its roots back to the ancient region of Macedonia in northern Greece. It is believed to have emerged during the Byzantine era, possibly as early as the 9th or 10th century.
One theory suggests that the name KIOUSIS is derived from the Greek word "kiousi," which means "column" or "pillar." This could indicate that the family's ancestors were involved in construction or architecture, perhaps as builders or stonemasons. Alternatively, the name may have originated as a descriptive term referring to a person's physical stature or strength.
Historical records from the Byzantine period are scarce, making it challenging to pinpoint the earliest documented instances of the KIOUSIS surname. However, a few notable figures bearing this name have emerged over the centuries.
In the 15th century, a monk named Demetrios KIOUSIS was renowned for his calligraphy skills and his contributions to the preservation of ancient Greek manuscripts. His handwritten copies of classical texts played a crucial role in safeguarding the literary heritage of ancient Greece.
During the Ottoman rule over Greece, which lasted from the 15th to the 19th century, the KIOUSIS family maintained a presence in the region of Macedonia. Some members of the family were involved in the Greek War of Independence in the 1820s, fighting against Ottoman rule.
In the late 19th century, a prominent figure named Konstantinos KIOUSIS (1856-1932) gained recognition as a Greek educator and writer. He authored several books on Greek language and literature, and his work contributed to the preservation and promotion of Greek culture.
Another notable bearer of the KIOUSIS surname was Georgios KIOUSIS (1884-1962), a Greek politician and diplomat who served as the Ambassador of Greece to the United States in the 1940s. He played a crucial role in strengthening diplomatic relations between the two countries during the post-World War II era.
More recently, in the 20th century, the KIOUSIS family has maintained its presence in various parts of Greece, as well as in the Greek diaspora communities around the world. While the name may have evolved in spelling or pronunciation over time, its Greek roots and historical significance remain intact.

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