Origin
Meaning and origin of Weglowski
The surname WEGLOWSKI is of Polish origin, tracing its roots back to the 14th century in the region of Masovia, located in central-eastern Poland. The name is derived from the Polish word "weglowski," which means "charcoal burner" or "coal miner." This suggests that the earliest bearers of this surname were likely involved in professions related to the production or mining of charcoal or coal.
The earliest recorded instance of the WEGLOWSKI surname can be found in the town records of Radzyn Podlaski, located in the Lublin Voivodeship of eastern Poland, dating back to 1412. The name is documented as "Węglowski," which was a more archaic spelling of the modern-day WEGLOWSKI.
In the 16th century, the WEGLOWSKI surname appears in various historical records and manuscripts from the Polish-Lithuanian Commonwealth. One notable mention is in the Metryka Koronna, a collection of royal decrees and documents from the Kingdom of Poland, where a certain Jan WEGLOWSKI is listed as a landowner in the town of Brańsk in 1562.
During the 17th century, the WEGLOWSKI name gained prominence in the region of Masovia, with several individuals bearing this surname appearing in local records and documents. One such individual was Tomasz WEGLOWSKI (1622-1687), a prominent merchant and landowner from the town of Czersk.
In the 19th century, the WEGLOWSKI surname became more widespread across various regions of Poland. A notable bearer of this name was Jan WEGLOWSKI (1832-1891), a Polish writer and poet who was born in the town of Żyrardów, near Warsaw.
Other historically significant individuals with the WEGLOWSKI surname include:
1. Stanisław WEGLOWSKI (1876-1942), a Polish Catholic priest and theologian who served as the rector of the University of Warsaw in the early 20th century.
2. Władysław WEGLOWSKI (1892-1972), a Polish military officer and diplomat who served as the ambassador of Poland to the United Kingdom during World War II.
3. Jerzy WEGLOWSKI (1908-1991), a Polish mathematician and professor at the University of Warsaw, known for his contributions to the field of functional analysis.
4. Henryk WEGLOWSKI (1917-2005), a Polish painter and graphic artist, renowned for his landscapes and still-life paintings.

Demographics
Ancestry and ethnicity for Weglowski
Among Census respondents with the surname Weglowski, the largest self-reported group is White at 96.1%.
The bar chart below shows how Weglowski bearers described their own race and ethnicity on the 2010 Census form. 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 Weglowski surname at the time of the 2010 Census, not any inherent property of the name itself.

Not necessarily. Weglowski appears here with 2010 Census data, while the latest surname file loaded on Name Census is 2020. When a surname drops below the Census publication threshold, older rows can still be kept for historical reference even if the name no longer appears in the newest file.
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
