Origin
The surname OLINN originated in the Scandinavian regions of Northern Europe, with roots tracing back to the Old Norse language spoken by the Vikings and Norse settlers. It is believed to have emerged during the Medieval period, between the 5th and 15th centuries.
OLINN is thought to be derived from the Old Norse word "ólinn," which means "ancestral" or "ancient." This connection suggests that the name may have been initially used as a descriptive term to identify individuals with a long family lineage or those associated with ancient traditions and customs.
Early records mentioning the surname OLINN are scarce, as written records from that era were often incomplete or lost over time. However, some historical references can be found in ancient Norse sagas and chronicles, which documented the lives and deeds of notable individuals.
One of the earliest known bearers of the name OLINN was Halfdan Olinn, a Norwegian chieftain who lived in the 9th century. He is mentioned in the Heimskringla, a collection of Old Norse kings' sagas written by the Icelandic scholar Snorri Sturluson in the 13th century.
Another notable figure was Thorvald Olinn, a Viking explorer from Iceland who is believed to have accompanied Leif Erikson on his voyages to Vinland (present-day North America) around the year 1000 CE. His name is recorded in the Grænlendinga saga, a historical account of the Norse settlement in Greenland.
In the 12th century, a Norwegian nobleman named Ketill Olinn is mentioned in the Njál's saga, one of the most significant works of Icelandic literature. He was a prominent landowner and chieftain in the region of Trøndelag, Norway.
During the Middle Ages, the name OLINN also appeared in various place names and toponyms across Scandinavia. For example, the village of Olinnskogar ("Olinn's Woods") in Iceland was named after an early settler with the surname.
Another notable bearer of the OLINN surname was Björn Olinn, a 14th-century Icelandic scholar and lawspeaker (a prestigious position in the Icelandic Commonwealth). He played a crucial role in preserving and transmitting the Old Norse literary and legal traditions.
As the name spread across Europe through migration and trade, it underwent various spelling variations, such as Olinn, Olin, Ohlin, and Ohlinn. However, the core meaning and connection to ancient Nordic heritage remained intact.
Demographics
Among Census respondents with the surname Olinn, the largest self-reported group is White at 96.7%. The next largest groups are Hispanic (1.7%) and Two or More Races (1.7%).
The bar chart below shows how Olinn 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 Olinn 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.
