Origin
Meaning and origin of Tomasik
The surname Tomasik originated in Poland, with roots dating back to the medieval era. It is a diminutive form of the Polish given name Tomasz, which is derived from the biblical name Thomas, meaning "twin" in Aramaic. The suffix "-ik" is a common Polish diminutive ending, indicating a smaller or more affectionate version of the name.
The earliest known record of the Tomasik surname can be traced back to the 14th century in the historical region of Lesser Poland. It is believed that the name first emerged as a way to distinguish individuals within a community, particularly those who shared the same first name. Variations in spelling, such as Thomasik and Tomaschik, were also common during this period.
In the 16th century, the Tomasik surname appeared in various historical records and documents from the Polish-Lithuanian Commonwealth. One notable figure was Jan Tomasik, a scholar and writer who lived in the late 16th century and authored works on theology and philosophy.
During the 17th century, the surname gained further prominence in the region of Silesia, which was then part of the Polish-Lithuanian Commonwealth. Records from this time period mention several Tomasik families residing in cities such as Wrocław and Opole.
In the 19th century, the name Tomasik appeared in various Polish literary works and historical accounts. One notable individual was Józef Tomasik, a Polish writer and journalist born in 1835, who wrote extensively about the struggles of the Polish people during the partitions of Poland.
Another prominent figure bearing the Tomasik surname was Antoni Tomasik, a Polish military officer and resistance fighter who lived from 1895 to 1971. He played a significant role in the Polish Underground State during World War II and was awarded the Virtuti Militari, Poland's highest military decoration, for his bravery and service.
Throughout history, the Tomasik surname has also been associated with various place names and locations within Poland. For example, the village of Tomasikówka in the Subcarpathian Voivodeship is believed to have been named after one of the early Tomasik families who settled in the area.

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