Origin
Meaning and origin of Lasica
The surname Lasica originates from the Slavic regions of Central Europe, specifically Poland and surrounding areas. It is believed to have derived from the Polish word "las," meaning forest or woods. This suggests that the name's earliest bearers may have lived near or worked in forested areas.
The name can be traced back to the 13th century, with records indicating its presence in medieval Poland. One of the earliest documented instances is found in a manuscript from the town of Krakow, dated around 1275, which mentions a landowner named Mikolaj Lasica.
During the Middle Ages, surnames were often derived from occupations, physical characteristics, or locations. The suffix "-ica" in Lasica likely denoted a connection to a specific place or region associated with forests or woodland areas.
In the 16th century, the Lasica name appeared in various historical records, such as tax rolls and land deeds. Notable individuals from this period include Jan Lasica (1510-1578), a prominent merchant and landowner in the city of Poznan, and Katarzyna Lasica (1535-1602), a noblewoman known for her philanthropic efforts in the region of Silesia.
As the centuries progressed, the Lasica surname spread across Poland and into neighboring countries, such as Lithuania and Ukraine, where it may have undergone slight variations in spelling or pronunciation.
In the 18th century, Franciszek Lasica (1725-1799) was a respected scholar and author who wrote extensively on Polish history and culture. Another notable figure was Ignacy Lasica (1780-1855), a military officer who fought in the Napoleonic Wars and later became a prominent landowner in the Krakow region.
The 19th century saw the rise of several influential individuals bearing the Lasica surname. Among them were Józef Lasica (1815-1878), a renowned architect who designed several churches and public buildings in Warsaw, and Natalia Lasica (1845-1920), a pioneering educator and advocate for women's rights in Poland.
Throughout its history, the Lasica surname has maintained a strong presence in various regions of Central and Eastern Europe, particularly in Poland, where it continues to be a relatively common family name.

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