Origin
Meaning and origin of Antoniuk
The surname ANTONIUK is of Ukrainian origin, deriving from the personal name Antonii, a variation of the Roman name Antonius. This family name emerged during the medieval period in the regions that now comprise modern-day Ukraine.
The name Antonius can be traced back to ancient Rome, where it was borne by several prominent figures, including the Roman general and politician Marcus Antonius, who was a key figure in the Roman Republic's transition to the Roman Empire. The name is believed to derive from the Latin word "antoniatus," meaning "priceless" or "invaluable."
One of the earliest recorded instances of the surname ANTONIUK can be found in the Halych-Volhynian Chronicle, a 13th-century historical record documenting the events of the Galician-Volhynian Principality. This chronicle mentions an individual named Antoniuk, who served as a nobleman in the court of Prince Danylo Halytskyi.
During the 16th and 17th centuries, the ANTONIUK surname appeared in various administrative and legal documents across the Ukrainian lands, particularly in the regions of Galicia, Volhynia, and Podolia. Notable individuals bearing this name from this period include Hryhorii Antoniuk, a Cossack leader who participated in the Khmelnytsky Uprising against Polish rule in the mid-17th century.
In the 18th century, Yakiv Antoniuk, a prominent Ukrainian scholar and philosopher, gained recognition for his contributions to the fields of education and theology. He was born in 1708 in the town of Zhovkva (now in modern-day Ukraine) and spent much of his life teaching at various educational institutions in the region.
Another notable figure was Mykhailo Antoniuk, a Ukrainian artist and painter who lived in the late 19th and early 20th centuries. Born in 1856 in the village of Kruty (now part of Kyiv Oblast), Antoniuk was known for his landscape paintings depicting the beauty of the Ukrainian countryside.
Towards the end of the 19th century, Oleksandra Antoniuk, a Ukrainian writer and activist, gained prominence for her work advocating for women's rights and education. She was born in 1872 in the town of Kozelets (now in Chernihiv Oblast) and authored several novels and short stories that explored the challenges faced by women in Ukrainian society at the time.
Throughout its history, the surname ANTONIUK has maintained its strong roots in Ukraine, with many individuals bearing this name making significant contributions to various fields, including literature, art, politics, and military service.

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.

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