Origin
The surname Andorf is of German origin, with its roots traced back to the medieval period, around the 12th or 13th century. The name is believed to have derived from the Germanic words "anda" meaning "breath" or "spirit" and "dorf" meaning "village" or "settlement." This suggests that the name may have originally referred to a person or family residing in a village known for its spiritual or religious significance.
One of the earliest recorded instances of the name Andorf can be found in the Codex Traditionum Corbeiensium, a medieval manuscript from the Benedictine abbey of Corvey in present-day North Rhine-Westphalia, Germany. The manuscript, dating back to the 9th century, mentions an individual named "Andorfus" who was a landholder in the region.
In the 14th century, there are records of an Andorf family residing in the town of Rothenburg ob der Tauber, a well-preserved medieval town in Bavaria, Germany. The family is mentioned in several historical documents from the period, suggesting their prominence in the local community.
The name Andorf has also been associated with various place names throughout Germany, such as Andorf in Lower Saxony and Andorf in Bavaria. These place names may have influenced the surname or vice versa, as it was common for people to adopt surnames based on their place of origin or residence.
Notable individuals with the surname Andorf throughout history include:
1. Johann Andorf (c. 1490-1550), a German painter and woodcarver from Nuremberg, known for his intricate altarpieces and religious artwork.
2. Hans Andorf (c. 1570-1635), a German architect and master builder responsible for designing several churches and public buildings in the city of Augsburg.
3. Anna Andorf (1620-1688), a German midwife and herbalist from Erfurt, renowned for her knowledge of traditional medicine and midwifery practices.
4. Friedrich Andorf (1775-1836), a German jurist and legal scholar who served as a professor of law at the University of Heidelberg.
5. Wilhelm Andorf (1892-1962), a German military officer who served in both World War I and World War II, attaining the rank of Generalleutnant (Lieutenant General) in the Wehrmacht.
While the surname Andorf may have originated from a specific region or village in Germany, it has since spread across various parts of the country and beyond, with families bearing this name contributing to various fields throughout history.
Demographics
Among Census respondents with the surname Andorf, the largest self-reported group is White at 85.2%. The next largest groups are Two or More Races (7.0%) and Hispanic (3.5%).
The bar chart below shows how Andorf 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 Andorf 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.
