Origin
The surname GREBENC is of Slovenian origin, originating in the late 16th or early 17th century. It is derived from the Slovenian word "greben," which means "ridge" or "crest," referring to a prominent geographical feature such as a mountain ridge or hilltop.
The name GREBENC likely originated in the Alpine regions of present-day Slovenia, where many families lived in villages and towns nestled among the rugged and picturesque mountain ranges. The addition of the suffix "-ec" or "-nc" to the root word "greben" suggests that the name may have initially referred to someone who lived near or on a ridge or hilltop.
One of the earliest recorded instances of the name GREBENC can be found in the parish records of the town of Škofja Loka, located in the Upper Carniola region of Slovenia, dating back to the early 1600s. These records mention individuals with the surname GREBENC, indicating that the name was already established in the area by that time.
In the late 17th century, the name GREBENC appears in the records of the Slovenian town of Radovljica, where a family of that name resided. This suggests that the name had spread to other parts of the region by then.
One notable bearer of the GREBENC surname was Janez Grebenc (1736-1801), a Slovenian painter and church fresco artist who was active in the late 18th century. His works can still be found adorning the walls and ceilings of several churches in the region.
Another individual of note was Matija Grebenc (1817-1892), a Slovenian author and educator who wrote several textbooks and educational materials for children in the Slovenian language. He played a significant role in promoting and preserving the Slovenian language and culture during a time when it faced suppression under foreign rule.
In the 19th century, the GREBENC surname also appears in the records of the town of Idrija, known for its historic mercury mining industry. A family by the name of GREBENC was involved in the mining operations in that area during that period.
Towards the end of the 19th century and into the early 20th century, individuals bearing the GREBENC surname can be found in various parts of Slovenia, as well as in neighboring regions of Austria and Italy, where Slovenian communities had settled.
One notable figure from this era was Anton Grebenc (1873-1962), a Slovenian lawyer and politician who served as a member of the Austrian Imperial Council and later as a member of the National Assembly of the Kingdom of Serbs, Croats, and Slovenes (later Yugoslavia).
Demographics
Among Census respondents with the surname Grebenc, the largest self-reported group is White at 95.6%. The next largest groups are Black (1.8%) and Asian/Pacific Islander (1.8%).
The bar chart below shows how Grebenc bearers described their own race and ethnicity on the 2020 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 Grebenc surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
