Origin
Meaning and origin of Enzenauer
The surname ENZENAUER has its origins in Germany, with records dating back to the 16th century. It is believed to have originated in the region of Bavaria, possibly deriving from a town or village name. The earliest known spelling variations include Enzenauer, Enzenaur, and Enzenau.
One of the earliest recorded mentions of the ENZENAUER surname can be found in the church records of St. Peter's Cathedral in Regensburg, Bavaria, from the year 1583. The entry lists a Hans Enzenauer as a resident of the nearby village of Obertraubling.
In the 17th century, the name appears in tax records from the town of Nittendorf, near Regensburg, where a family by the name of ENZENAUER is listed as landowners and farmers. This suggests that the name may have originated from a small settlement or farmstead in that area.
The first recorded instance of the ENZENAUER surname outside of Bavaria can be found in the parish records of St. Michael's Church in Freiburg im Breisgau, in the year 1694. Here, a Johannes Enzenauer is listed as having married a local woman named Anna Maria Bauer.
One notable bearer of the ENZENAUER name was Johann Baptist Enzenauer, born in 1771 in the village of Schierling, Bavaria. He was a respected scholar and theologian, serving as a professor at the University of Landshut and later as the Bishop of Regensburg from 1827 until his death in 1838.
Another individual of historical significance was Maximilian Enzenauer, born in 1842 in the town of Straubing, Bavaria. He was a renowned architect and engineer, known for his work on several prominent buildings in Munich, including the Bavarian National Museum and the Theatinerkirche.
In the late 19th century, the ENZENAUER name began to appear in records from other parts of Germany, as well as in neighboring countries like Austria and Switzerland, likely due to migration and population movements during that time period.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
