Origin
Meaning and origin of Kubilis
The surname KUBILIS is of Lithuanian origin, and it can be traced back to the 16th century in the region of Samogitia, which is now part of western Lithuania. The name is thought to be derived from the Lithuanian word "kubilys," which means "a tub" or "a barrel." This suggests that the name may have originally referred to someone who made or sold tubs or barrels.
One of the earliest recorded instances of the name KUBILIS can be found in the records of the Samogitian Diocese, where a certain Jokūbas KUBILIS was mentioned in a document dated 1587. This document pertained to a land dispute between the KUBILIS family and another local family.
In the 17th century, the KUBILIS name appeared in the records of the town of Raseiniai, which was a major center of trade and craftsmanship in Samogitia at the time. Several members of the KUBILIS family were listed as coopers or barrel-makers, which further reinforces the connection between the name and the word "kubilys."
One notable figure in the history of the KUBILIS name is Jonas KUBILIS (1755-1832), a Lithuanian writer and translator who was born in the village of Skaudvilė. He is known for his translations of various religious texts into the Lithuanian language, which played a significant role in the preservation and promotion of Lithuanian literature during a time when the country was under foreign rule.
Another prominent individual bearing the KUBILIS surname was Andrius KUBILIS (1810-1885), a Lithuanian farmer and landowner who lived in the town of Varniai. He is remembered for his efforts in promoting agricultural education and modernization in his region, as well as his support for the Lithuanian national movement.
In the 20th century, Antanas KUBILIS (1902-1986) was a Lithuanian politician and diplomat who served as the Prime Minister of the Lithuanian government-in-exile during the Soviet occupation of Lithuania. He played a crucial role in keeping the idea of an independent Lithuania alive during the difficult decades of Soviet rule.
Marija KUBILIENĖ (1898-1978) was a renowned Lithuanian writer and poet who wrote under the pen name "Žemaitė." She is considered one of the most important figures in Lithuanian literature, known for her vivid depictions of rural life and the struggles of ordinary people.
Lastly, Alfonsas KUBILIS (1920-2009) was a Lithuanian-American engineer and inventor who held numerous patents in the field of mechanical engineering. He made significant contributions to the development of various industrial machinery and equipment, and his work earned him recognition both in Lithuania and in the United States.

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