Origin
The surname Lerz originated in Germany, likely in the late 12th or early 13th century. It is believed to have derived from the Old German word "lerche," meaning "lark," which was a type of small songbird. This suggests that the name may have initially been given as a nickname to someone who was known for singing or having a melodious voice.
One of the earliest recorded instances of the name Lerz can be found in the historical records of the city of Cologne, where a certain Henricus Lerz was mentioned in a document dated 1295. This suggests that the name was already well-established in the region by that time.
In the 15th century, there are records of a family with the surname Lerz residing in the town of Rothenburg ob der Tauber, a well-preserved medieval town in Bavaria. The family was involved in the local textile trade, and their name appeared in various guild records and municipal documents of the time.
During the 16th century, the name Lerz began to spread beyond its original German heartland. In 1532, a man named Hans Lerz was recorded as a citizen of the city of Zurich, Switzerland, indicating that the name had crossed the border into neighboring regions.
One of the earliest notable individuals with the surname Lerz was Johann Lerz (1592-1670), a Protestant theologian and author from Nuremberg. He was a prolific writer and published several works on religious topics, including a commentary on the Book of Psalms.
In the 18th century, the name Lerz appears to have been relatively widespread across various German states and principalities. For example, records show that a family with the surname Lerz was living in the town of Marktbreit, located in the present-day state of Bavaria, during this period.
Another notable figure with the surname Lerz was Karl Lerz (1805-1888), a German author and journalist from the town of Ludwigsburg in Württemberg. He was a prolific writer and contributed to various publications, including the influential Augsburger Allgemeine Zeitung newspaper.
As the 19th century progressed, the name Lerz continued to be found across different parts of Germany and neighboring regions. For instance, a man named Franz Lerz (1825-1901) was born in the town of Mühlhausen in present-day Thuringia, and went on to become a successful businessman and industrialist.
Overall, while the surname Lerz is not among the most common in Germany, it has a long and well-documented history, with its origins traceable back to the medieval period. Throughout the centuries, individuals with this name have made contributions in various fields, including theology, literature, and business.
Demographics
Among Census respondents with the surname Lerz, the largest self-reported group is White at 98.2%. The next largest groups are Two or More Races (1.8%).
The bar chart below shows how Lerz 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 Lerz 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.
