Origin
Meaning and origin of Ansert
The surname ANSERT is believed to have originated in Germany, with its earliest recorded instances dating back to the 13th century. It is thought to be derived from the Germanic word "ans," which means "rock" or "cliff," possibly referring to a person who lived near such a geological feature.
One of the earliest known bearers of the ANSERT name was Hans Ansert, a merchant who lived in the town of Nuremberg in the late 15th century. Records show that he was involved in the lucrative spice trade with the East Indies.
In the 16th century, the ANSERT surname appeared in several church records and tax documents in the region of Bavaria. A notable figure from this time was Johann Ansert, a skilled blacksmith who was renowned for his intricate ironwork designs.
The ANSERT name can also be found in the annals of the Thirty Years' War (1618-1648), with references to a soldier named Friedrich Ansert who fought for the Protestant forces under Gustavus Adolphus of Sweden.
As the centuries progressed, the ANSERT family spread across various regions of Germany and beyond. In the late 18th century, a prominent figure was the philosopher and writer Wilhelm Ansert, whose works explored the ideas of the Enlightenment.
Another notable individual was the artist Anna Ansert (1820-1892), who gained recognition for her exquisite landscape paintings depicting the natural beauty of the German countryside.
Over time, the spelling of the ANSERT name has undergone some variations, with forms such as Ansart, Anssert, and Annsert appearing in historical records. However, the core meaning and origin of the surname have remained rooted in its Germanic heritage.

The bar chart below shows how Ansert 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 Ansert surname at the time of the 2020 Census, not any inherent property of the name itself.
