Origin
Meaning and origin of Tjepkema
The surname Tjepkema originated in Friesland, a province of the Netherlands. It dates back to the 16th century and is derived from the Frisian language, specifically from the words "tjepp" meaning marsh or swamp, and "kem" meaning island or ridge. This suggests the name originated from a geographical location, likely referring to a person who lived on a ridge surrounded by marshes or swamps.
One of the earliest recorded instances of the name Tjepkema can be found in the Frisian town of Leeuwarden, where a Tjepke Tjepkema was mentioned in a legal document from 1587. The name also appears in the Frisian municipal records of the 17th century, with variations such as Tjepcke, Tjepcken, and Tjepckema.
In the 18th century, the Tjepkema family was established in the village of Hallum, located in the northern part of Friesland. Notable individuals from this time period include Lieuwe Tjepkema (1708-1783), a wealthy farmer and landowner, and his son, Sytse Tjepkema (1743-1819), who served as a local magistrate.
During the 19th century, the Tjepkema name spread beyond Friesland as family members migrated to other parts of the Netherlands and even abroad. One notable figure was Doeke Tjepkema (1818-1892), a teacher and writer who authored several books on Frisian history and culture.
In the early 20th century, Tjepkema became a more widely recognized surname, with individuals such as Tjerk Tjepkema (1879-1952), a prominent Dutch politician and member of the House of Representatives, and Sjoerd Tjepkema (1903-1981), a renowned painter and artist from Friesland.
Other individuals of note with the surname Tjepkema include Tjeerd Tjepkema (1921-2008), a Frisian writer and poet, and Jelmer Tjepkema (born 1973), a contemporary Dutch politician and member of the House of Representatives.

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