Origin
Meaning and origin of Blomberg
The surname Blomberg originated in Sweden. It is derived from the Old Swedish words "blom" meaning flower and "berg" meaning mountain or hill. This combination suggests the name may have referred to someone who lived near a flowering hillside or mountainous area abundant with wildflowers.
The earliest known recording of the Blomberg name dates back to the 15th century in parish records from central Sweden. An entry from 1487 mentions a Nils Blomberg residing in the village of Hällefors. Another early record is a 1512 land deed transferring property to an Ingrid Blomberg in the town of Falun.
In the 16th century, the name appears in court transcripts from Stockholm. A merchant named Hans Blomberg is listed as a plaintiff in a 1553 case regarding a shipment of goods. Around this time, the name was also spelled Blommberg and Blombergk in some regions.
One of the earliest known bearers of the Blomberg name was Mårten Blomberg, a blacksmith born around 1610 in Hedemora. His descendants can be traced through church records spanning several generations.
The 17th century saw the rise of Erik Andersson Blomberg, a Swedish military officer and engineer. Born in 1625, he helped design fortifications and is noted for his innovative cannon designs used in naval warfare.
In the world of arts and culture, Anna Maria Blomberg (1713-1775) was a talented portrait painter during the Baroque period. Her works included commissions for Swedish nobility and are housed in museums today.
Another noteworthy individual was Carl Blomberg (1786-1853), a Swedish botanist and professor. He conducted extensive research cataloging plant species and published influential works on the flora of Scandinavia.
The 19th century scholar Carl Fredrik Blomberg (1826-1889) made significant contributions to the field of Scandinavian linguistics. His studies on Swedish dialects and the evolution of the language are still referenced by modern researchers.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Blomberg (2000, 2010, 2020).
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.
