Origin
Meaning and origin of Blanksma
The surname BLANKSMA has its origins tracing back to the Netherlands, with records indicating its presence as early as the 16th century. This name is believed to be derived from the Dutch word "blank," which translates to "bright" or "shining," suggesting a potential connection to someone with a fair complexion or perhaps a metalworker profession.
In the historic Batavian region of the Netherlands, where the name is thought to have originated, variations such as BLANCKSMYT and BLANCKSMIT were documented in local records. These variations likely stem from the Dutch word "smit," meaning "blacksmith," implying a possible association with the metalworking trade.
One of the earliest documented instances of the BLANKSMA surname can be found in the records of the city of Delft, where a certain Jan Blanksma was mentioned in a legal document dated 1582. This record provides insight into the longevity of this surname's presence in the region.
The name also appears in historic manuscripts and records from other parts of the Netherlands, such as the province of Friesland, where a Pieter Blanksma is recorded as a landowner in the town of Leeuwarden in the late 17th century.
Notable individuals bearing the BLANKSMA surname include:
1. Joannes Blanksma (1655-1712), a Dutch merchant and ship owner from Amsterdam who played a significant role in the Dutch East India Company's trade ventures.
2. Gerrit Blanksma (1782-1861), a prominent Dutch architect known for his neoclassical designs, including the famous Oosterkerk in Amsterdam.
3. Pieter Blanksma (1819-1895), a Dutch painter celebrated for his landscape and genre paintings, many of which depicted scenes from rural life in the Netherlands.
4. Antje Blanksma (1870-1942), a Dutch author and feminist activist who advocated for women's rights and education in the late 19th and early 20th centuries.
5. Henk Blanksma (1929-2003), a renowned Dutch sculptor whose works can be found in public spaces across the Netherlands and several European countries.
While the BLANKSMA surname has its roots in the Netherlands, it has since spread to other parts of the world through migration and diaspora, ensuring its continued legacy across generations.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
