Origin
Meaning and origin of Lozowski
The surname Lozowski is of Polish origin and can be traced back to the 16th century. It is derived from the Polish word "łoza," which means "willow tree." This suggests that the name likely originated as a locational surname, referring to someone who lived near a willow grove or a place where willow trees grew abundantly.
One of the earliest recorded instances of the Lozowski name can be found in the historical records of the town of Lublin, located in eastern Poland. In the year 1587, a document mentions a certain Jan Lozowski, a local merchant and landowner. This provides evidence that the name was already well-established in the region during the late 16th century.
During the 17th and 18th centuries, the Lozowski name appeared in various Polish aristocratic and noble families. Notable individuals from this period include Wojciech Lozowski (1620-1688), a renowned military commander who fought in the Polish-Swedish wars, and Anna Lozowska (1712-1782), a philanthropist and patron of the arts.
In the 19th century, the Lozowski surname gained prominence in the field of academia and literature. Józef Lozowski (1806-1876) was a respected historian and author who wrote extensively about Polish history and culture. His contemporary, Kazimierz Lozowski (1818-1897), was a prominent linguist and translator known for his work on translating ancient Greek texts into Polish.
As the Lozowski family dispersed throughout Poland and beyond, the name underwent slight variations in spelling, such as Lozowsky or Lozovsky. One notable figure with this variant spelling was Artur Lozovsky (1892-1936), a Soviet trade union leader and politician who played a significant role in the early years of the Soviet Union.
Throughout its history, the Lozowski surname has been associated with various professions, including military service, academia, arts, and politics. While the name originated in Poland, it has since spread to other countries due to migration and diaspora communities, carrying with it the legacy of its Polish roots and the symbolic connection to the willow tree.

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